A circuit breaker trips because there was an overload on the line. A tripped breaker may indi- cate that you have too many AC devices working off the same line or that you have faulty building wiring. If the breaker is not tripped, but the lamp doesn’t light when plugged into the outlet, replace the outlet or have an electrician check the line.
