Hello forum. Couldn't find the virtual pub so I thought I'd dive right in.
I have a problem with the RCD tripping when the circuit is off. I discovered it earlier today while replacing a single socket with a double. Circuit was confirmed off with a plug in socket tester. Pulled the wires together to pull through the old back box and 'pop' the RCD tripped
. I was able to repeat this on demand.
I had a similar problem a short while back which I put down to a faulty tester (an old Steinal). Putting it across live and earth or live and neutral tripped the RCD on both rings. However doing the same with my multimeter had no effect. It just read 230 something volts. At the time I presumed the tester had had it
I've had no issues with the electrics since moving in last year and the plug in neon socket tester suggests all sockets are correctly wired.
The house is about 12 years old. CU is the original Wylex with 2 rings, immersion heater and outside lights protected by a 80A / 30mA RCD.
What is the likely cause of the RCD tripping? Is it something I can trace and fix myself (I have a circuit tester, a multimeter and a fair amount of common sense)? If not, what should I be asking an electrician to ensure they have the skills and tools to fix?
