    My 50 amp breaker at the bottom just tripped I’m trying to figure out why. Is there too many amps being pulled in the house? I don’t use that top Left 50 amp breaker. the 50 amp is wired with 6/2 wire to a sub panel that pulls 8000 watts. It’s definitely oversized. The project called for 40...

    Single Module Double Pole RCBO over 40 amps?

    With for example the Wylex NXHL1B Single Module DP range of RCBO's there is (at last) a sensible solution to RCD protection for all circuits individually, but only up to 40 amps. Is there a manufacturer doing 50 amp single module double pole rcbo's e.g for thirsty 10 kw or 11 kw large cookers...

    Max amps from UK socket

    I have been told I can use a 30Amp welder from a normal UK socket. But I have seen numerous posts that say 13amp is max from single socket and 20AMP is max from double socket: I must be missing a trick. Some internet postings below. "Double sockets are rated for 20A draw, over this long term...
