Hi
I have just been changing some sockets in my conservatory.
My consumer unit has two banks on it. This circuit was on a secondary bank (i.e. not the one with the main switch) and is protected by an RCD.
I had the individual circuit turned off via it's breaker, but left the rest of the bank on. Confirmed no voltage on the circuit from the live/neutral and stated to work on it, however when I was trimming the wire back, the RCD on the secondary bank tripped. The primary bank remained live.
I thought this was odd but continued to work on the circuit, but I then got a mild shock when I touched the wires.
I tested the wires again using the circuit tester and this time checked the earth wire. The live and neutral were still reading 0 volts, however the earth was reading 33 volts.
I turned the main bank off at the main switch and checked again - this time zero volts on the earth.
I fitted the new sockets and turned both circuits back on. Everything seems to be working fine and the new sockets work - but i'm a little worried that this isn't normal.
I did have the consumer unit relocated and replaced last year, but everything tested fine as far as I know and there has been no further work on the electrics since then.
All of the wires are bundled closely together into the consumer unit. Could the reading on the earth be down to an induced current. Is it something I need to be worried about?
Thanks
