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!)
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
@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! 😂
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!
@TheChipmunk2008 It's a tough one mate. The I stall has been fine for 50+ years then you come along and say 'na, it needs upgrading'. It will probably be fine, if I'm coming across this issue, odds are the rest of those types of issue are present aswell. So I'd probably C2 for the undersized older tail aswell as all the other stuff wrong with the install leaning towards a rewire or at least a DB/bonding upgrade.
@@John_Faultless We ended up passing it after notifying SSEN, turns out it was theirs, not a BNO.... the conduits were straight runs from the basement so they ran new concentrics through!
@TheChipmunk2008 This is where the problem lies. Our rules are in place so that landlord can still rent their property despite it being unsafe as all we can code is a X for anything before the meter. This rule benefits the slumlord and the failing DNO. Not the poor sod living there......
@@John_Faultless Yes we're lucky down here as SSEN are quite responsive to faults. Apparently, same company in scotland is not, they're woefully understaffed and will leave people with dangerous situations for months. My friend has even had to change tails as the metering company refuse to touch em even tho they're now their responsibility!
@@_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 😁

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 👊

and in my feed this week is a video from Bright Spark Electrical where he's had a Starbreaker main switch not making full contact on the plug-in busbar and start burning itself up... never seen any issues with the Starbreakers I've swapped out, but I guess anything is possible ua-cam.com/video/UCm9oEn25HA/v-deo.htmlsi=cJEfq97Kw2osh_L5
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.
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.
@HeathenGeek The number below is the energy class. 3 being the best. Class 3 let's through 1.5 joules/seconds. So even with a high pfc, there's a good chance these modern mcb will trip with a high pfc.
Thank you John 🙂🇮🇪☘️
Nice informative video John. Good stuff
@sergiofernandez3725 Cheers mate 👊
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

The square D breaker with the blade connector can be modified to screw connector by removing the top insulating part and removing blade.

Hello John, hope you're well. Enoch
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 😞
