A frequently tripping breaker usually means the circuit is overloaded, there is a short circuit, or a breaker is failing.

Yes, and most significant electrical work in Janesville requires a permit from the City of Janesville Building Division. Your licensed electrician should pull the permit on your behalf — be cautious of contractors who suggest skipping permits to save money.
