Incorrect Circuit Breaker Size Can Lead to a Fire Hazard A #12 gauge aluminum wire is rated for no more than 15 amps, otherwise you risk overheating the electrical wire which may cause a fire hazard. The replacement 20 amp circuit breaker should be turned OFF and a new 15 amp circuit breaker should be installed.
Do you need special breakers for aluminum wire?
Make sure that the breaker is labeled “AFCI” (arc fault circuit interrupter), which is made specifically for applications with aluminum wiring and can sense and prevent electrical arcing from starting fires.
Can I use a 15 amp breaker instead of 20?
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.
What size aluminum wire should be used with a 20 amp breaker?
The perfect wire gauge of a 20 amp breaker is the #12 AWG wire.
Why are some breakers 15 and some 20?
The wires from a household electric circuit can carry up to 20 amps and in most settings, there are a few 15 amp recipients that connect to a 20 amp circuit breaker. The reason behind that is to allow several devices to plug in to the same 20 amp circuit, without overloading the system.

What happens if you put a 15 amp outlet on a 20 amp circuit?
In most home installations, several 15-amp receptacles connect to a 20-amp circuit breaker. This allows multiple devices to connect to a single 20-amp circuit as long as the total circuit load does not exceed 20 amps. If the load exceeds 20 amps for a long duration, the circuit breaker will open the circuit.
When should I use 15 amp or 20 amp?
Appliances, such as microwaves, often have 20-amp plugs and must be plugged into a 20-amp outlet. Electrical plugs designated as 20-amp will not fit into 15-amp outlets. A 15-amp circuit is usually served by 14-gauge wire and is protected by a 15-amp circuit breaker or fuse.
Can I use a 15 amp switch on a 20 amp circuit?
You can, in fact, use a 15-amp switch on a 20-amp breaker lighting circuit since the 20-amp rating means that the circuit can handle anything up to 20 amps, so anything lower is alright to use.
What is the difference between 15 and 20 amp breaker?
A 15 amp circuit normally includes 14-gauge wires, while 20 amp circuits use 12-gauge or 10-gauge wires.
How many outlets can be on a 15 amp circuit?
8 outlets
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.
