Came across this the other day, was asked by a friend to have a look at a shower which was tripping.
they had a new replacement shower fitted recently the plumber disconnected the old shower and reconnected the new one.
I found neutral and earth cross connected at the shower unit. So no tests can of been done before reconnecting the cable to the new shower.
It was also a 8.7-9.3kw shower feed with a 6mm cable the cable was run in the loft so was only rated at about 34 amps on 40amp breaker.
Why can’t plumbers stick to plumbing and not fiddle with electrics!!!
