What is the formula used to determine the correct amperage circuit breaker? I am rewiring an older home, and, having done some electrical work in the past, know that the right amperage circuit breaker can be calculated; I just don't know the formula. Can anyone help?

14awg=15amp breaker (used only for lighting)
12awg=20amp breaker

In general, use 15amp for lights and most general duty (tv, stereo,vacuum cleaner) circuits. If you will plug in an appliance (freezer, refridgerator, space heater, microwave, etc) go with a 20amp breaker and 12/2 wire.

Anything else such as an electric dryer, etc then call in a pro.

Use 14awg-15 amp breaker for lights only.

While the amperage/use guidelines suggested have been correct, the bottom line should be the wire that connects to the breaker. Even if the circuit is used for heavier duty applications, you shouldn't put a 20 amp breaker in if the wire is 14 ga.
