    Would you expect an electric shower to draw amps in this way?

    I just went to replace a 45A pullcord for someone as it had stopped working. It's only been in a year so I assume it must have been a loose connection during installation as a couple of the connections, particularly neutrals, were very loose in the switch but fine at the board and in the shower...

    Which is better BS1361 or BS88?

    Was wondering why was BS1361 replaced by BS88 even though BS1361 tends to have a larger breaking capacity according to the on-site guide if I'm reading it right, however, I maybe wrong. For example BS1361 breaking capacity can be 16.5kA to 33kA depending on what type you get, where BS88 is 16kA...

    How many total amps is this??

    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...
