Had an electric shower installed two days ago. Before the shower was plumbed in the electrician came and wired the shower unit. 10mm cable with a Contactum shower RCD and a new 45amp cartridge fuse on my very old Wylex unit.
Anyway, I plumbed in the water to the shower today and went to test the shower. As soon as I switched the shower on the RCD tripped. Now the shower will trip the RCD the moment it is turned on (and btw, this is only turning the cold water on, not even the heat element!).
HELP!!
When the electrician left he turned the shower on (with no water) and the light was on, the RCD did not trip.
This is what has changed since he left:
1) Water plumbed in.
2) 45amp fuse pulled (as was borrowed from neighbour) and new 45amp fuse replaced.
3) I used expandable polyfiller foam in a very large hole the electrician drilled for the 10mm cable. Probably not a good idea.
Nothing else has changed!!
Before I phone the electrician up and moan, does anyone have an idea of what could have happened?
Thanks,
Simon.
