Hi guys
I have a 10a RCB on my consumer board feeding my garage.
In the garage (from the 10a feed) I have a socket spur RCB which feeds armoured cable to a submersible pump that should turn on to pump out water from the bottom of my garden.
Quite frequently now, the RCB on the consumer board (in the house) is tripping, due to the pump and not the RCB on the socket spur which the pump is connected to....!!
I've turned off the pump to test it is the pump that's tripping the RCB and it looks like that's the cause of the problem as the RCB doesn't trip when the pump is connected to the feed.
How can that be?
I would have thought the socket RCB would trip before the consumer board RCB "up current" of it...?
Any thoughts?
Cheers
