How to Evaluate Overloaded Circuits Do you have a branch circuit breaker that trips open intermittently? Do you have an Edison Base fuse that blows out intermittently? Then the chances are good that you have an overloaded branch circuit. There are a couple of ways you can determine if an over load exists on any given circuit. One way is to connect a recording clamp-on Watt meter or Ampere meter to the circuit in question and read the load present when the breaker trips open or the fuse blows. Recording meters are expensive and not something that most DIY electricians will want to invest in. An alternative method is to calculate the total load connected to the circuit.

What to Do when a Circuit Breaker Trips Intermittently If you have a circuit breaker that continues to trip open intermittently, you may have a defective breaker in the panel, an overloaded circuit, or an intermittent short-circuit. Jerry Walch published this 163 months ago   +14 votes
