After an outage, everything is starting at once – motor loads, in particular, tend to draw a very large current at startup – if a circuit has several motor loads which do not usually start at the same time, it may not trip in normal service, but if all the motor loads start at the same time, it may trip.
What will cause a breaker to trip again after it is reset?
As with hard shorts, a ground fault causes an instant reduction in resistance and an immediate increase in electrical flow. This causes the internal mechanism of the circuit breaker to heat up and trip. As with hard shorts, if a ground fault is present, the circuit breaker may trip again immediately after you reset it.
Should I be worried if my breaker keeps tripping?
Don’t ignore a circuit breaker that keeps tripping. This is a sign that one of your circuits is getting overloaded on a regular basis. Your circuits are only able to handle up to a certain level of voltage. Beyond this voltage, you run the risk of starting an electrical fire.
How many times can you reset a tripped circuit breaker?
Now, if you happened to plug in several appliances to that circuit AND you know the draw of the total of those appliances is greater then 15 Amps, then, and only then should you reduce the load on that circuit (unplug things), reset the breaker – only once.
