I have two RCD's in the main switchboard.
They rarely trip and I am confident that there are no wiring or leakage issues, however, one does trip when we experience abnormal power spikes.
I have a standby generator that will kick in automatically when there is a distinct power outage after more than 2-3 seconds and in those circumstances, the RCD is fine.
The most recent event was this week. My house/office was drawing 5-6 Amps only, no major appliances were running, only my office PCs, servers and other equipment mostly all on UPS. A quick 'double cut' outage and surge tripped the RCD again.
I'm trying to avoid this happening because the standby generator (which is there to keep the office running 24/7) becomes useless if the switchboard RCD has popped and there is no-one nearby to manually reset it.
Does anyone know of solutions to this issue or maybe other options for mains power buffering or filtering?
