Brilliant fantastic work
Lovely
Great
Nice knowledge about variety of reds
Very important to understand RCD and also time delays one
Thank you
Very good video.
Very informative.
Thanks
Nice informative video John. Good stuff
@sergiofernandez3725 Cheers mate 👊
There ARE some 3871s i believe that were 6/16/32 etc. My favourite plug in breakers are the crabtree starbreaker you couldn't find any of, the boards are SO safe to work on, NO exposed busbar whatsoever
Edit, you just covered that, and green was 45A in BS1361 fuses, and the breakers for wylex, there was an orange as well... 40A (also a pale green, B10!)
Not a electrician but I still found this interesting 😂
Agree with the small van - I have a Peugeot Part er and it’s too small - should have got a vivaro or an expert. Keep up the videos - I really want to see you succeed at this, you deserve it
@mikegmarshall Cheers mate, really appreciate it 👊
Question for you John... VIR tails.... (the braided kind) from henley block (which is where the incomer usually would be) to meter , it's a block of flats so probably a BNO rather than DNO responsibility, C3 or C2? they seem to be in good condition, not breaking down... but woefully undersized and faded.... The incomer to the flat is actually those singles in a piece of 20mm conduit!
Another fun fact, those wylex RCDs will trip on a dc continuity test! We tried to do an R1+R2 on the output side of one (for convenience) and the spike of 200mA dc would pop the rcd!
And you're totally right .... I code AC and 4293 RCDs as C3 now, so still satisfactory as it was compliant at the time of installation :)
It boils my p*ss when sparks do an unsatisfactory on things like plastic CUs... it's a C3 ONLY unless there's other problems like not tripping on time, or at all (looks sideways at BG)
Bonus fun fact, MEM rcbos can't be tested at the terminals, as the terminal is BEFORE the sense coil/element, the actual line conductor 'hole' is the sense coil! Trips people up all the time if they try RCBO time tests at the breaker terminals.
Excellent 👍 Should do one about CU’s per Reg Edition ❤
@zjzozn I regret throwing out all the old consumer unit's now! I deffo wanna get a little collection started to do a few videos about them. I'll have to start hording again! 😂
Hello John, hope you're well. Enoch
Lovely big dual direction RCD......
It’s made by Keter - McAllister one is good as well
The square D breaker with the blade connector can be modified to screw connector by removing the top insulating part and removing blade.
@@johnflower8648 I didn't know that. Thanks mate 👊
thumbnails got ya again 🤣 stab-lok looks a similar idea to Crabtree Starbreaker, not sure which came first. Quite like those, no messing about, plug it in and off you go. Am a Trainee working mostly on council stuff, hence using the older brands.
@avocet89 Mate, I think they're doing it on purpose 👀 I'm not sure which came first but the Stab-Lok seems really secure.
Yea old council stock is a great way to learn mate. There's great work and......not so great work but a great variety which is what you want to become a great sparks 👊
@@John_Faultless should be able to choose or upload your own thumbnails, RUclips Studio if that shows for you when logged in? Council stock can be varied, can be a nice old couple in a spotless home one day, and a crack den the next. 🤣when I took this job in 2021 it was on occupied rewires, while that's a bit samey week in week out, it taught me how a house is/should be wired . Now I'm working on voids (much preferred) , upgrades, the occasional responsive work... a good variety.
7:42 the Wylex MCB conversion thingy says '2000' (obvs 2kA) with a '2' in a square below it.
19:15 the Hager MCB says '10000' (obvs 10kA) with a '3' in a square below that too.
What do the numbers in the squares mean? Enquiring minds. . . and possibly some stoned ones need to know.
And yes you're right re: the C50s, the colour code did indeed tell you the breaking capacity. From a brief google, white is 3kA and yellow is 4.5kA
Also they might have a code sticker on them M3 is 3KA etc
Mmm... Note to self... Don't comment before watching the video 😞
@@_eusty nah it's fun to chat along, at least for me :)
@@_eusty Ah sorry, i thought you were having a go at me lmao... as a greybeard (if i let it grow) i do forget that for new apprentices a lot of this is ancient history rather than 'i installed that last year, oh wait 35 yrs ago',. and really appreciate what John is doing here
@@TheChipmunk2008 I'm no younster either!
I agree that even though I knew what John said and used most of the MCB's he had (although never seen any Federal ones) it was a really interesting video 😁
Great video. Do you recommend double pole RCBO’s on TT installations?
@@lukeaxon5404 I would recommend them for all installations. I use them as standard on my installations. For the sake of a few £ I would say they're worth it.
What make is that work bench?
Made by Keter
@@mikegmarshall thank you.
They need qr code on mcbs etc and takes you to spec that us on the side
@BillsCountrysideAdventures 100% mate. My eyes aren't what they used to be 😂 I need all the help I can get!
@@BillsCountrysideAdventures The Schneider Acti9 ones have just that 😁
