RCD trip time

[freddo]

the test button simulates earth leakage by putting a resistance across L and E

Not since the days of VOELCBs! The test button uses a resistor to link the incoming L to the outgoing N to create an imbalance.

i stand corrected.

Still nice to know the timing and how to test them need be. Yes testing is frowned upon on US forums.

Testing is not frowned upon in the US were just not required to do all the testing that UK has to do. But we have inspectors that come and check our work
