Truth and reconciliation with Thomas Nagy! This kid gets it! The paperwork, bidding jobs, bits and pieces, billable hours, He's on it! Liked this video.
I was with you on the 20 amp upstairs (at 6:06) ring until recently. Board change at a nice 4-bed house with a decent installation. Called back for the RCBO tripping. Wife and two daughters using hairdryers at the same time. Do these things really need to be over 2Kw each! Good to see you back on form. Content and quality unmatched in nice lil' sub-20 minute packages. Sod the the "it's an easy money spinner" brigade. Some of us have followed you since college and now out there, inspired by what you showed us.
Naomi’s laugh is as infectious as Alesha Dixon’s on BGT. She’s a nice addition to the channel. Keep it up!
Innuendo?
No alesha Dixon's is not infectious it's annoying. Naomi's is infectious.
The Ferrell kits are ace, best thing I’ve brought in a long time, works fine down here in the south coast for now. Keep up the good work Tom
Proper job mate screw what people say you can walk away from there knowing you did everything right and everything is safe
Thom here where I am (Texas) I have been real busy and I have small company as far as pricing work I have a motto and that is Skilled labor ain’t cheap and cheap labor ain’t skilled
That's a good motto.
Union Motto 😉
LOL your face at the end when she said , Need more length. Another great video mate.
IT Service here, between everybody having had to build their home office, and the businesses taking the off-time to take a closer look at their office IT, I have never been busier in the middle of the year.
Good video as usual Tom, totally agree with you about doing cert on site, home time is your time. Nice to see the little sauce pot at the end, having a laugh at work is priceless.
You should side those ferrules on without twisting the strands something I was told by an automation spark working in car plants, good video though Tom always learning new tricks
Caterpillar state not to twist the wires too. They also say not to butt the insulation on the wire all the way up to the crimp on non-insulated terminals because if the wire moves it can lever the conductors from the crimp (that's on engine, off highway kit mind, so probably not applicable to a fixed inatallation)
FYI
Breakers on the din rail on the back door. I used to do that until I realized that when it's raining it isn't doing the breakers any good. Moved them into the van, onto the front of a racking shell. Much better, trust me!!
That’s what the rain seal around the back door is for.
@@Zombie_Longwinger don't think he means when the door is closed 😂
Most people keep their doors closed on their van, irregardless of the weather.
Been using ferrules for over twenty years & I'd never go back! Watch out relying on the colours as there are three different colour schemes - French, Weidmuller & German/DIN 46228.
Doing your certs on the go is just the "right" way to do it, it may make the onsite work marginally longer, but saves time in the long run because you're not writing the numbers down twice!

Always on a learning curve from a pro.
keeping the circuit low, couldn't agree more. I'm also a believer of every room has it's own circuit, coming from a software developer background, modularisation keeps everything simple, scalable and easy to check
Have been using ferrules in cabinet building for years. Had an electricien tell me that, according to regulations, it wasn't allowed (something about making better contact because of larger surface area bladibladibal...) Good to see taht you (and others) are starting to use them now on stranded wire.
Always love seeing the van storage ideas in your videos!!
Top Tip! Record result ONSITE! Why would you not? Another good job Mr N!
PMSL, Naomi is a LEGEND already!
The bootlaces crimp better (and go on easier) without twisting the cores I’ve found. Used them pretty much every day for the last 14 years in control panels.
I weird control panels for nearly 3 years and it taught me so much! how contactors work, relays, drawings... loads of things great thing for all sparks to have experience in
It's actually bad to twist the strands because it makes the contact surface smaller.
That's why in Germany it's not allowed to twist the strands.
@@scwfan08 It's true that excessive twisting is not recommended, but the wire is already twisted and a light twist to maintain that and make the strands go into the connector is OK.
@@scwfan08 yeah I got told not to twist strands either, if you just pull them base to tip it should straighten them out and slide them on without any whiskers
I use some of the ones without plastic 'funnels' also (handy in plugs). Those do require twisting slightly, but yeah the ones with plastic funnels don't need twisting. As I'm getting older tho they do require reading glasses LOL
after being made redundant i'm glad to be back at work. was climbing the walls whilst on furlough for the company to magically go into administration 2 weeks ago. working on commercial site in Glasgow city centre as well
Just had a mooch in the BBB and found the following two that seem relevant regarding the need to use ferrules.
526.9.1 states "in order to avoid inappropriate seperation or spreading
of individual wires of multi wire, fine wire or very fine wire
conductors, suitable terminals shall be used or the conductor ends
should be suitably treated."
526.9.2 states "soldering (tinning) of the whole conductor end of multi
wire, fine wire and very fine wire conductors is not permitted if screw
terminals are used. "
it's nice to see you work sir in my country there are no jobs or workers and yet the crisis has started i don't work at all
You should put the din rail inside, so they don't get wet when you have the door open, just an idea . I think Tom/dave doing a runner again did you a huge favour, compered to your new apprentice, he was as boring AF. 😂 She is a breath of fresh air!
We do the cert on site (on laptop) but ALSO write the readings down in a desktop diary we keep in the van. The NICEIC site sometimes shites itself halfway thru a cert, and in any case, you can then look back to the readings if you get a question :)
With regard to domestic work, we're finding it's coming back up in level (south coast). Got a couple of rewires coming up that had been put off due to lockdown.
And good tip about the DIN rail on the van.. we've just started doing that, colleague bought 3M of din rail (cheap as chips, not worth messing with ones removed from boards LOL)
In order to keep customers going during board changes, we have a 30A main fuse that we put in the holder, and we fit a temp board on 6.0mm from the meter terminals. The temp board has 3x twin sockets on a B20 and a 6A for temp lights if needed, (oversleeved the cores and made off the terminals so they don't show bare copper). Not strictly to regs, but keeps the customer happy and it's only for a couple of hours, while supervised
I do Data Cabling, CCTV and Access Control. Was working in Canterbury last week, had to drive to the site, unload every possible tool I might need from the van and then park my van in the closest car park - some 10 minute walk away. The of course the reverse of that when it comes to going home. Can’t believe how long it takes and what it adds to the job. That and the £40 parking cost for a couple of days.
Its truly mad. That's the bit people dont see and how much time it adds to a job
From my perspective, I do mostly domestic over in Essex. Majority of homeowners now honestly don’t seem to care anymore, I try to be as compliant as possible when I’m on site but I can’t help thinking a lot people are frankly bored with it all. I work alone and I’m as busy now as I was before it all kicked off !
Those ferrules are ace treated my self to a kit!. There all fun and games untill you knock the box open with the lid open!
i did that with my terminal crimps ...... i was not a happy boy to say the least.
My old apprentice did that on a job once. Made him put every single one back in the right place.......needless to say, he never did it again 😁
Then its boo bag time 😂
@@andljoy me too 😊
You want the box with a rotating lid so only one size of ferrules fall out each time you tip it over :)
That power bank seems like a really good idea.
Especially in your job.
Probably been said before but we dont use ferrules in NZ for 230v. The general consensus is that they have pinch points which can cause heating. Same with power distribution. Looks great though when you remove the cover.
bang on about the retro fitting and making it neat sometimes its near impossible, Marine side we have used bootlaces for years.
Work has been weird here i am at the northern isles in scotland and we have been hit hard frims going to the wall, hotels closing for good and a airport closing up, could not work until there was pemission from the gov and could only do domestic work this last week, but the work is here but far less than it was, i have a few contract for maintance which will see me good but it is concerning to see that there is nobody really trying to help those in need goverment wise. Great content again
At least in the US you are required to use the ferrule crimper that is specified by the ferrule manufacturer for UL compliance. Ferrules are often required for finely stranded wire [i.e. Class K] if the terminals are not rated for it. Can't remember the BS 7671 regs on them. We just use them everywhere because it also makes it easier if you have to pull a wire out the strands are not all mangled, saves so much time for the next guy.
I was literally just thinking "haven't heard from Tom in a while!" now for the video, hope you're keeping safe!
my preciva and ferrules arrived today, nice bit of kit
I find the concept of using ferrules is predominantly better using Tri-Rated cable especially if working in singles or panel building also very neat with the compatibility and wear tear very good ? The only downside when they are adjacent it can be a squeeze dependant on terminal room ie relay bases and small component fixtures 👍
I find keeping my test results in my megger box is helpful Tom. Might help when you don't have your laptop to take results. At least then they can stay safe and you know we're they are.
Im a plumber but do my own wiring on programmers stats and 2 ports etc and the ferrules are a god send been using them for several years.
Work has been slow until two weeks ago but now coming in quick and fast.
Good to see you’re using your Edmundson Electrical notepad Tom!
I love that pack of ferrules. I've been using mine for a few weeks now.
I can relate to your comments on pricing. I'm always wondering am I overpricing or under pricing but there will always be someone who will do it cheaper. At the end of the day I'm like you, I price for a good professional job that I can walk away from and sleep soundly at night knowing everything is safe. I don't fit cheap tat!!
I'm a spark in Germany and work is going on as usual if not more. I don't feel any difference apart from the new annoying virus rules. Keep your head up and stay safe, greetings from Germany.
Hi Tom
the Ferrule crimps are such a professional finish and the only safe way to shorten a manufacturer's neutral tail, I'm also a big fan of filling your certificates as your testing no mistakes should then be made, works never been busier for me anyway, I know theres loads of guys out there not in the same position.
Are you and playing innuendo bingo every time you work together??
Keep up the excellent work Tom 👍👍
Good video! Unfortunately in Hungary we don't use RCBOs, if you go to the store and say I want an RCBO the look like strangely :D
Also we use RCD-s with MCB-s. Separately for the bathroom, general lighting, sockets.
Your spot on with the cowboys fudging the eicr. I take at least 4 hours, if not a whole day depending on size and quality of property. I've heard that those companies are basically giving a quick visual inspection then taking Zs values and the odd rcd test. I like to be a bit more thorough. Workwise, I've been laid off and now looking for work. I'm in Scotland and there's not much going up my neck of the woods
What make of cherry picker are you looking at buying? Boot lace ferrules make a tidy job 👍
Always use ferrules on stranded cables if they're going into a screw terminal. The strands spread out too much and you can't guarantee a full connection otherwise. On the big stuff, 25mm conductors we used to bind the stranded ends with a single strand of copper.
The new Schneider Acti 9 DBs are brilliant for rcbo installs, as they don't have flyleads, so they look much neater.
Electricians are keeping busy where I am, in Middle Tennessee, in spite of COVID and the recession. There is a lot of new construction and expansion, 2nd quarter saw an all-time record for permits. So I guess we're lucky.
When testing Continuity on ring final circuits I disconnect the other rings in the dis-board incase you have a mix up if ring legs. obvs you'd discover that once re-energised as you'd have an imbalance in the rcd.
I made a video about that Ferrule Kit vs the Knipex £120 one. Nice!
As you've got the Knipex one Jordan, do you use that rather than the cheaper one?
Have you given the one you don't use to Chris?
@6:27 you got that the wrong way round, the efficiency is going up i.e. they are getting MORE efficient.
Going to be installing 18 way RCBO board soon. will try the ferrules !
Plenty of work here in Somerset but working 2 weeks on 2 weeks off at the mo, Please remember we are in a pandemic and going into lots of different homes and work places. Im not sure what precortions Thomas is taking off camera but i dont see him taking any ( his decision ). Love the vids and the good work he carries out but if people dont want us in there homes we're going to be out of business.
Please all trades men/ women respect your customers safe zones ( there homes ) otherwise we may be in trouble. Our customers are paying us good money to make there homes safer, Mask up and clean hands, its simple really.
About the testing/certification. Why the faff about doing it on site?
If you do it right away, you're done when leaving the costumer. and you can fully focus on the next task
Going the extra mile as usual! Love the ferrules.. a nice touch mate. I enjoy watching your organisation, makes me keep my ass in gear haha! Too easy to become lazy these days
Do you subtract time it takes to set-up camera gear, lighting, find your mic and replace the gopro batteries from your bill or do you give clients a fixed discount when you film?
hey a few vids back you had a hand little saw and said it relaces 20 volt etc what make and were to buy if you remember please
⚡️Sparks to the Stars 🌟
Tom the regulation you were looking for is 526.9.1
I'm surprised you're not using rechargeable batteries mate , i bought an energizer quick charger and I use the batteries every single day for my lights etc , they charge so fast you can use your light all day long just by swapping batteries and charging them right away , saves the environment and money at the same time 👍
Just starting on my own in January... Just picking up work now. Southern England.
Are you new to the trade? Or just new to working for yourself?
With crimp terminals, you are not supposed to twist the wire strands too much. A very slight twist so they go in the terminal is fine. But nothing more. The idea of the crimp is to make an airtight seal onto the wires. This is more effective if there is no twisting of the wire strands.
At work for me at the momen, the company i do work for (self employed contracted by the same company- basically employed) we are extremely busy at the moment. We do lots of work for various property agents , meaning there are a bucket load of eicr’s for us to do and also jobs coming in that people have been waiting to do or needed before/ during lockdown, which they want done now.
Have to agree... ferrule kits are ace. As an extremely low user I couldn't justify a full kit so bought all the sizes I needed in small quantities off Ebay along with some ratchet crimp pliers for less than £30 quid. Keep them in the packets they came in plus the pliers in a click lok box.
Yep back feeds 🙄 I was replacing light fittings on a block of flats once and half way through noticed a spark. Guess what the whole board was off but there was a back feed from a secondary board on the lift room. From there on off isn’t off until the meter says so.
@6:24 How can a kettle get more efficient? It's a resistance heater. They're 100% efficient at converting electricity to heat. Most of that goes into the water. Even a better insulated kettle still uses the same power, just for less time.
I say more efficient; actually they just downrate them. The same as hoovers are now restricted to 1600W. I dont think they have done it to kettles yet but they will with time. My bad; poor terminology.
thomas nagy it seems mad to do it with kettles as that would only make them less efficient as they’ll require a longer boil time there more energy lost to the surroundings. At least with vacuum cleaners you can designed more efficient motors and piping to allow better suction per watt thermal losses and make them quieter
Tom, check out the Weidmuller PZ6 Roto ferrule crimper. Great for doing control panels, quick n easy to use and does an excellent crimp.
@ Thomas Nagy,
Been using boot-lace ferrules since about 1990 in control cabinets and switchboards, I don't know why anyone wouldn't use them, like you say, they make the whole thing neater and they negate having things like short-circuits happening, one thing a lot of people don't realise is that they are obtainable in sizes up to 50 mm² and you could probably get larger ones if you needed them.
The 4-jaw crimp tool is a necessity, we had a lot of failed crimps with the 2-jaw ratchet crimp tool over here in New Zealand
Oddly enough, I'd like your opinion if I may, what are your thoughts on these "new" screw-less clamp terminals that are starting to appear with a few devices, like industrial switches and the like.
I tried some and they clamp quite solidly, I was originally stand-offish about using them, but I'm converted, especially with ferruled conductors.
Work-wise, I'm flat-out, since the lock-down here, I have a back-log of about 2-3 months work and I'm looking to take on a 2nd apprentice or try and find a qualified electrician.
Cheers,
Mike T.
Before I do a board change, I inform the client, (be they home owners or landlords) that I will first conduct an eicr. The reason is very simple and I explain it like this. When you have a plain wooden door, you would primer it first before you put the final coat on? Well it the same with this only, you need to know where the underlying problems are before you replace the board for new. Makes my job much easier and if you do have issues directly from doing an eicr, you can clear them with the customer first before you end up looking like an eegit!!
Best way, Shear! I'm finding like Tom I'm getting approached for budget "landlord" EICRs.. It is hard to know what's best for pricing, if you end up having to change the board...if you did the "sample test" method for the EICR, you open up a can of worms on the board change. Chiefly, because Johnny DIY has left an inaccessible connection in a wall somewhere. Happy hunting!
Strugling to find an apprenticeship to be honest nothing out there on the sites hopefully they come around shortly if not back to college to complete the level 3
What magnet are you using on your iPhone case. Perfect for meter/board areas.
Always a good day when your vids come out :D
So Tom, how do electric heaters like kettles or space heaters get more efficient when already 99%+ of the electricity gets converted into heat?
8:46 You can hide the search that's taking up a quarter of you taskbar. Right click on an empty part of the taskbar and go to search, you can hide it completely or turn it into a small icon.
There are some good ones that you can tow behind the van
Yiu can get Ferrells in different sizes, any color you like.
The problem I have is I don't know what size to get. There super cheap and you can buy in bulk. Cheers
Yeh, nah, I wouldn't be twisting the wires going into the bootlace ferrules. I also strongly recommend using a Knipex 12 62 180 wire stripper which helps set the length perfectly for the ferrules every time
100% agree with you about landlord's not being interested weather the installation is safe they just want a report with satisfactory on it. I get numerous calls about doing EICR for £100 all in, the sad thing is someone will done it and fudge the results or LIM everything.
Hi Tom, ferrules are great use them for doing bms
There needs to be some prosecutions for the crappy Eicr and the scams(schemes) need to remove some peoples certification.
Great video thanks for sharing. Just wonder how long it will be before, god forbid, a tenant is injured with a bodgit and scarper eicr.
The same amount of time it’ll take for a tenant to get injured because of a bodgit and scarper landlord who’s been doing his own stuff to keep costs down for year’s. The only difference is the landlord will have a get out clause because of the “eicr”
Hi Tom, So far as coping goes I haven't stopped work as we are contracted with southern water so we are classed as key workers. I have managed to use the time to also finish my NVQ and have now qualified as a spark. now I just haft to go forth into the world and get more experience as I still feel I don't know enough. How long after you qualified did it take for you to feel like you knew what you were doing?
Years. I think its just a long process that you never end.
I still come across stuff that makes me stop and think now. everyone does i guess.
You'll make a bunch of errors to start, just learn from them and keep going.
@@thomasnagy cheers mate
This is a bit off topic but do you do asbestos checks when doing rewires?
to sound like Julian Ilett test the output of the powerbank to make sure it put out 50Hz with a clean sinus wave because letting any client connect any expensive or important non resistive load to it.
the off sider sounds like a keeper
Nicely done
I want to train as an electrician after my studies, all this stuff u do Thomas is very intimidating yet so so interesting, anywhere I can learn electrican basics before I start my course so I can have a huge headstart???
Do a college course or just go for an apprenticeship, if you do a college course first then you’re more likely to get an apprenticeship because it shows you really do have an interest and want to do it
Glad to see you now use a Megger....
If they can connect a blue wire inside of that RCBO, surely they must be able to put a screw terminal there instead? I don't understand why all those breakers have a wire pre attached.
Hi Please could someone point me in the right direction for the model of ferrule crimpers and crimps used in the video, Many thanks in advance
Working in the events/entertainment industry life is currently a furlough based one. On the note of not actually knowing what life will be like on the otherside of this and the fact I'm paying extreme prices for a two bedroom flat in Reading, I'm really smashing through as much as I can to get an electricians apprenticeship. Its great to see a Electronic and Electrical Engineering degree means nothing to companies without an added 18th Edition. 😂😂
Here in Eastern Canada im super busy but not with residential work. Mostly Commercial renovations
Great vid again mate 👍🏻🏴
I’ve been working flat out for my firm since COVID kicked in bar having two days off at the start when nobody knew what was going on.
Council work died until about June, so I was mainly doing 3 phase board changes and eicrs for office blocks. Had a few rewires too
Now I’m back doing council repair and maintenance since June. I’d rather be on the commercial side again but it pays the bills i guess
Here in Brazil , it's a difficult situation. But I go to clients everyday, but because there are no airplanes... All is done by car ( most of the trips, 1000-3000 km) that's the hard part and with all the necessary precautions..
There is a regulation mate, can’t tell you the number and I’m not getting up to get the blue bible ! But it says something along the lines of stranded wire that is at risk to damage under termination must be terminated using a crimped end to protect the cable 👍🏻
The company I work for specializes in commercial and bio-med electrical. I work in the Service department. I was working 5 days a week up tell 4 weeks ago when I fell off my roof and bruised my pelvic bone and broke a rib. I'll be going back to 5 days a week in two weeks if my doctor signs off.
It will be interesting to see how the EICR gets positioned in the rental sector. It could work out well for landlords in respect of DIY horrors or tenants not meddling. On the other hand, it might end up like an energy performance cert, which means not a great deal, but gives tenants an opportunity to act up if they're served notice and don't have a copy.
Hey Thomas do you mainly specialize in low voltage ?
That is some size ring circuit. Assuming its 2.5mm line and neutral then that works out to 145 meter ring which is above the max 100 meter. But either way it was already installed so who cares but just thought I would point it out. Love you vids!
I got the same kit, same crimp and everything , i even use them when i wire a plug , its so cool..... am i sad ?
Also little nit pick i know but a kettle is a restive load , it cannot get any more efficient :P
I caught that too. And while small appliances tend to use less power now that tends to be as much because of upper limits (set by the dreaded EU) as improvements in efficiency
Kettle boils faster with Avon water.
Upstairs rings are where everyone plugs in their 3kW fan heaters on those frosty mornings while they get dressed isn't it? oh perhaps it's just me.
Only up north, when the gas pipe freezes lol! I agree with you, however. It's why we have 13A plugs, and expected loads on domestic rings are calculated for 3kw heaters (for those that don't know..)
In London, even in the spring, the concrete maintains an ambient temperature akin to a BBQ pit roast on Mercury! It gets hot! Still would feel robbed sticking a ring on a B32 though...
