Was selling my cement mixer yesterday, and when selling, tried to show it to the buyer working in the shed. when plugged in and switched on, it just tripped the RCD. I reset it and it happened again. Finally when connected to the house supply via extension lead i was able to show him it working.
Why did the RCD trip. It wasn't damp or anything yesterday evening?
I now want to put a washing machine in the shed. Will this cause the RCD to trip?
Thanks for any assistance.
