Hi, just wondering if any sparkies or plumbers/shower fitters can offer me some advice?
Had my Mira Escape shower for a few years and all has been fine, but a couple of nights ago whilst I was in the shower, it tripped out and I noticed a burning smell.
I opened the shower unit up and sure enough the neutral cable has melted badly:
I checked the other end which runs into the pole switch and all is fine there with no sign of damage:
Is there anything in particular that could have caused this?
The cable runs from a 50amp rcd in the circuit board - into the pole switch - then into the shower. There aren't any signs of water seeping into the unit.
The other thing that is confusing me is that when the shower is tripping out, it's not tripping the 50amp rcd that it's connected too. Instead its tripping a different one out which has a 'test' button on it.
This other rcd with the test button is supplying power somehow? If I switch this rcd off, then pull the pole switch there is no power and vice versa, if I turn the 50amp shower rcd off and leave the test one on, there is no power on the pole switch? Both have to be on.
Hope I've explained myself ok, and hopefully get a bit of advice. I'm a chippy so know a little about electrics, but not that much. Got a few sparkies in work that could take a look, but that won't be until next week and with this scorching weather, it's killing us not having the shower :cry: :cry:
