Hello, I just wondered if somebody could help me with a question I have please ?
My garage is powered by 15M of 3-core swa cable of 10mm csa via a metal box where the cable changes to 10mm t+e to enter the house cu and terminates onto a 32A mcb.
The cu in the garage is a metal unit and the swa goes staight into that.
The sockets are fed by a 16A mcb and the lights by a 6A mcb. There is a 63A rcd in the garage cu.
The main house feed is tn-s from an aged lead cable.
All this info is on a sheet of paper nicely included in the house cu - very thoughtful I guess !
Anyway, I want to add a water supply to the garage (just a cold supply) from the house and seeing as I have loads of 22mm copper pipe laying around, I was going to use that, buried deeply in my garden to protect from frost.
Simple so I thought until a friend of mine who is training to be an electrician said that I will have to get an electrician in to earth the pipework and put a spike into the ground near the garage for this earth.
Wouldn't the pipework already be earthed, seeing as it is soldered into the house pipework ?
Is this something an electrician definitely has to do or is it something a diy junkie like myself can do ?
Can anybody guess at a reasonable cost for this ?
I forgot to add that the house is about 65 years old if that makes any difference.
Thankyou.
