Should I use 15 or 20-amp breakers?
My smaller breaker keeps tripping!” The answer: It’s possible, but not advisable without an electrician evaluating the situation. You should never just upgrade from a 15-amp breaker to a 20-amp one just because the current one is tripping. Otherwise, you may burn your house down via electrical fire.
Is a double 20-amp breaker 40 amps?
Nope. It means that two 20 A breakers are ganged together to protect a circuit using two hot wires. Tripping either one at 20 A will trip both to prevent a safety situation where live voltage can be found in the device after one breaker tripped.
How many circuits can be on a 15 amp breaker?
Technically, you can have as many outlets on a 15 amp circuit breaker as you want. However, a good rule of thumb is 1 outlet per 1.5 amps, up to 80% of the capacity of the circuit breaker. Therefore, we would suggest a maximum of 8 outlets for a 15 amp circuit.
