Hi Everyone
Had to replace an old Re-wirable fuse board last week in a small industrial unit, replaced with a split load board, originally had the compressor wired into the RCD protected side and everytime the compressor started it tripped out the RCD.
I have since moved it to the other non rcd protected side & it works fine. The compressor is protected by a 32A MCB has two motors which start with a time delay (I.E. one motor starts & runs and then the other) to prevent overload. I measured the start current to be 38A and the current when running is 23A.
I know the compressor does not need RCD protection, Just wondered why the RCD trips?
Thank you
