You were pulling excessive amperage through the leg without the breaker tripping to protect the circuit from the overload, resulting in overheating of the overloaded leg.

What causes a main breaker to get hot?

In addition to excessive current flow, circuit breaker overheating can be the result of poor quality electrical connections. Poor electrical connections increase the resistance to the flow of electrical current, resulting in the generation of heat.

How do you know if a circuit breaker needs to be replaced?



You will need to replace a circuit breaker if it is hot to touch, has a burning smell or you can see visual damage such as black or burned material or frayed wires. Quality circuit breakers should last a long time. The circuit breaker device doesn’t necessarily cause every electrical problem or short circuit.

How many times can a breaker trip before it should be replaced?

While some circuit breakers can last longer, arc fault (AFCI) and ground fault (GFCI) type breakers have a shorter 10- to 15-year life because the internal sensors wear out quicker than the breaker itself. Circuit breakers should be replaced every 15 to 20 years or as issues arise.

Can you replace a 15 amp breaker with a 20 amp breaker?

If your wiring is of the correct gauge, you can change a 15-Amp circuit breaker to a 20-Amp breaker. A 15-Amp circuit uses a 14-gauge wire. A 20-Amp circuit breaker uses a 12-gauge wire. If the copper wire is 12 AWG, you can replace the 15A breaker with a 20A breaker.

When should I replace my main breaker?



Breakers should be replaced on average every 25-30 years. Additionally, they can come by to take a look. If your circuit breaker is old but not too old, you can pay for their visit without having to pay around $2,500 for the replacement.
