Hello and what a great forum!!
A few years ago we undertook a complete renovation of our 2 up 2 down semi and also added an extension, doubling the footprint and the bedrooms and as per 'Grand designs' et al my wife announced she was pregnant just as we started the project!!
We hired local trademen and by and large were pleased with the results until it came to the electrician fitting the shower a few weeks after moving back in. we had acomplete rewire and provision for the shower was already in place from 1st fix, a cold water feed from below and real chunky cable from above (scuse my terminology )
The shower was fitted by the electricians underling (it was a Gainsborough 9.5 sc) and all seemed ok until i found a small piece of plastic in the bath (the shower is situated at one end of the bath)
On closer inspection i could see wire between the backplate of the shower unit and the tiles and so gave him a call and he came round and re-arranged things inside, tipped his hat and bade farewell.
Upon use the shower started to trip the rcd after about 5 mins use. He declined to answer any further contacts so we have been putting up with quick showers for a couple of years until it gave up the ghost last week!
I thought if i buy the same or equivalent shower it should be a straight swap so yesterday took delivery of a Gainsborough 9.5 se and was chuffed all the entry points and fixing points were the same. Turned off power, water and removed cover to expose the insides. 1st thing I noticed was a small plastic label instructing the amount of outer insulation to be removed from the power cable and this had been totally ignored, mit was stripped back about 200mm back into the wall. the tiles had been removed and a holed gouged out of the brickwork behind barely covered by the shower cover. to cut a long story short I have managed to fit the replacement correctly with the right amount of insulation stripped off but I can see down the back between the back plate and the tiles and it still trips the rcd after about 5 mins.
The shower is about a 12m cable run from the consumer unit and the cable is extremely thick and each of the live and neutreal has about 7 x1.5mm solid cores to it, the ground may be slighly less at 1mm x 7 cores. the only info on the fuse is Hager MTN 132 B32.
Any advice will be thankfully and gratefully recieved
