Can I mix 12 and 14-gauge wire?
More specifically, can you connect 14-gauge wire to 12-gauge wire? While this is possible, it is not recommended in order to prevent overloading. For example, if the amp capacity of your breaker is 20 amps, you should only use 12-gauge wire, and if it’s 15 amps, the entire circuit should be 14-gauge.

How many outlets can be on a 15 amp circuit?
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.
