Each breaker size requires a different wire size based on the breaker’s ampacity.How to Calculate What Breaker & Wire SiTo calculate circuit breaker and wire size: Write down an approximation of the total load you will connect to the circuit breaker. Get a circuit breaker rated for 5% of this load. Make sure the wire it will be paired with has a higher ampacity than the circuit breaker's rating.Breaker Size CalculatorThe wire size will be determined by the breaker size and the amp load of the circuit. Wire is sized by gauge, or the diameter of the wire. In electrical wiring it is referred to as AWG (American Wire Gauge). The gauge of the wire determines how much electricity is capable of traveling through the wire.What Size Wire Do I Need For Breaker? (FeedbackPeople also askWhat size wire will fit in a 100 amp breaker?The rule of thumb for 100 amp service is that you go with a wire size gauge 1. 5 amp requires a wire size 2/0. For 150 amp, the right wire size is 3/0. For 200 amp service, you will want a wire size 250 kcmil.
