Hi,
I've been called to a job today where the customer had recieved a bad shock touching some metalwork.
I've been and checked it out and found a couple of faults, but am stumped on one. I found the live had shorted to the backbox, and blown up the socket. They had got another "electrician" out who replaced the socket but had left it with the live and earth terminals the wrong way round. This was the reason he got a bad shock when he touched his caravan which was plugged into mains.
I've rectified these faults, but am getting some funny readings when i now test the socket. When I try a Zs test on the socket it wont let me perform the test, it says >50v, it also says V1 and 3 phase rotation is ok. This is a puzzle as its a single phase. I've checked the voltages which are ok between live and neutral / live and cpc. Neutral and Earth though produces 17v. I tested the other sockets in the kitchen which gave me good reading, and this socket was on the same circuit. I could'nt get access to test the CU as it was buried.
What should I be looking for when I go back. Any tips as I'm abit unsure what might be causing this fault.
Cheers
