At my tennis club there is a circuit breaker which has a reset button, whech, apparently, needs to be "pumped" in order to reset it. I've never heard of this before, and I wondered if anybody could shed some light on the subject.
FYI, it is connected to about 6 socket outlets in the kitchen, nothing out of the ordinary.
