The first article in this series on electrical wiring acts as the table of contents for the series.
Wires of different sizes (called gauges) are capable of carrying different amounts of current, which is measured in amps.
It is critical the circuit breaker that protects any circuit be of the right amps rating for the size of the wire.
If the breaker is rater for more current than the wire, you have a dangerous situation. See below.
Per the national electrical code, the rules in the United States and Canada is:
|Wire Size||Wire Rating (Amps)||Breaker Rating (Amps)||Common Use|
|#14||15 Amps||15 Amps||Lighting Circuits|
|#12||20 Amps||20 Amps||Outlet Circuits, Dedicated Microwave Circuits|
|#10||30 Amps||30 Amps||Heavier duty electrical appliance (oven, dryer, etc)|
|#8||45 Amps||40 Amps||Sub-panel feed line, Specialty equipment with a big motor|
|#6||65 Amps||60 Amps||Main service feed – older home|
|#3||105 Amps||100 Amps||Main service feed – newer home|
Most circuits in your home are 15 amp (lighting circuits) and 20 amp (outlet circuits), but no matter what, it is again CRITICAL that breaker rating be appropriate for the wire rating.
If the breaker rating is too low, the breaker will trip before the wire capacity is close to being reached.
If the breaker rating is too high, the wire can get too hot and potentially start a fire!!!
