Got called yesterday from a customer in a panic yesterday.
The bathroom upstairs had sprung a (bad) leak. I'm not a plumber but was called to help in a panic ie switch water off, isolate leak etc meantime.
Anyway the water was following its normal course along the downstairs ceiling and out the light fitting.
The light was still on so I switched the MCB off at the board.
A little while after isolating the leak and stopping the flow of water I removed the light from the ceiling. The light has a 'bowl' type design with the rim of the "bowl" sitting flush with the ceiling and the connections inside the "bowl".
The connector blocks (L,N,E) were sitting in 1" of water.
Shouldn't the MCB have tripped itself as soon as water connected with the terminals?
