    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!)

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

    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!

    • @John_Faultless
      @John_Faultless  2 місяці тому +1

      @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.

      @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......

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!

    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.

    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.
