Case History: I have two houses in the Phillippine Islands. When I am hunting for the circuit breaker that turns off an outlet, I find that one-of-four breakers can be tripped to interrupt the circuit (as long as the three other breakers are open). If I throw the first breaker, the light goes out, but if I turn it on and throw circuit two, the light goes out (same with three and four). This occurs in both houses and it is really throwing me off for an explaination.
