This is an initial verification so you can’t omit insulation resistance testing between the live conductors, you do the test before any vulnerable equipment is connected.
When IR testing, I was always told to make sure the CPC was connected to the earth bar in case there's any insulation failures where the live conductor is in contact with something grounded that isn't the CPC for the circuit (particularly relevant with metal containment systems etc)...
That’s correct all CPC’s, bonding conductors and the earthing conductor should be connected when carrying out an insulation resistance test.

Nice job Nick apart from the faraday cage already mentioned, is there anything in the regs about mounting extraneous equipment inside the fuse board? (just asking)
Mounting an RF device inside a metal box.... you have invented it's own personal Faraday cage Nick! Be interesting if that drops out in the future when more RF noise is introduced in an operating environment. Would be worth drilling a small hole and routing the antenna outside the consumer unit mate
Good shout mate thanks 👍
Yes I was about to comment the same...I'm a radio engineer and radio waves won't propagate through metal..nor through water...😁
Yep I've had it with Quinetic stuff, grid switch modules sharing a metal backbox/grid with normal (earthed) mains stuff... range was cut to less than 3 metres!
I was thinking the same. Faraday cage
Well more in an outdoor situation perhaps where there's lots of vegetation that gets wet when it rains or damp stone walls
Grid switches should carryy an earth stud on the grid for fly lead to back box
love watching your video's Nick aswell as dave and jordans, in an ideal world i'd love to come and work with you as i feel i'd learn so much, keep up the great work. crap 16th edition ex spark to thick to pass his 18th.
Whats the R1 + R2 link like? Iv never used one, personally i couldnt see it as solid a connection for your reading, compared to using a wago or connector
Good video nick , Why not use click plug and base system on the conduit through boxes ? it makes for easy replacement of light fittings and testing 👍🏾
haven't seen them before mate (im a house basher remember)
@@NBundyElectrical Never seen Hager Klik! 😮😮😮
Customer was cost cutting as usual wants it all for the cheapest price lid and stuffer is a cheaper way unfortunately
What are the regulations in regards to mounting board materials for both 230v and 415v fuseboards/consumer units?
Lighting looks spot on. Nice conduit (not condooit 😆)
Is it ALUUUminum condooit............
Rcd test at the board, much easier.
Imagine having 30 rcbos you can test them all in 2 mins, and with just 2 leads.
Update on sleeve it?
Ever forgotten to take your magnetic link off before powering up the board?
LOL, we have an R1+R2 plug for radials on EICRs... I learned never to carry it at the same time as a socket tester. :D
No earth to the yoke of that grid switch mate.
Banjo or serated washer is normal practice
You have to ir test between L/N on a new job
Ah ...nick has remembered the amazing Mr. Faraday.....so all that studying wasn't in vain..🎉
You can`t do an R1+R2 using the conduit due to the parrallel paths you need to do an R2 long wander lead to everything on the circuit and record the highest reading
There is only one circuit in galvanised tube
I was meaning that as the conduit is the cpc and not a cable the R1 + R2 reading will be a false reading as the conduit is bigger and could branch off to metal trunkings so giving a lower reading so only an R2 should be taken, testing at all exposed conductive parts on the circuit and recording the highest reading.@@brightsparkmid
It goes from one side of the wall to another and attached to a stud wall, yes if attached to other stuff would be a different story. This was a simple circuit to be honest
Are you warming to the new megger ?
Its in the mi not to put the recever in a metal box
Same Nick …i wish i had a Dad
Mitch is so insensitive isn’t he
@@NBundyElectricalyup
He is …….i wish I could tell my Dad that I teach Apprentices now at a Technology College instead of being on the tools…….
Hi Nick Is this a channel for electricians only , I’m asking because I’m not one but find it really interesting to watch, but you might as well have been speaking Chinese as I don’t know what all these IR tests and stuff are about.
IR stands for insulation resistance, basically you know if you touch live to neutral or cpc you get a short circuit resulting in a nice bang and a bright flash, well because of this the live cable needs to be insulated from the neutral or cpc
IR testing is just testing the soundness of the insulation along the entirety of the circuit. You send 500 volts dc down 1 cable and make sure nothing comes back on the other. Its measured in Megohms or Millions of Ohms, 0.5 Megohms is the lowest allowable in the regulations but the higher number the better, >999 like Ted had means the value is higher than 999 Million Ohms
RCD's and RCBO's work by monitoring the outgoing Current (Amps) on the live and the incoming current on the Neutral, it should be the same. If there is a higher difference than 0.03 of an Amp the device will trip. So if your Neutral and Earth were touching you wouldnt get the nice bang and flash like if the live was touching, but all your current from the neutral would be going down the earth cable instead, making the higher than 0.03 imbalance tripping the RCD constantly
Thank you
Its a BUS BAR ........ NOT A BUZZZZZZZZZZZ BAR.
Na I like buzzzzz better 🫶
The bar is a bus delivery system for the power. That's why it's name is 'bus bar'. Same name used in everything from PC mother boards upto mains grid switchgear.
But it makes a buzzing sound when theres loads of power going through it
👍 first one here
But last in the list 🤣
