30 Amp Circuit Breakers

30 amp breakers are used on 10 AWG copper circuits (NEC 240.4(D)). The most common are 2-pole 240V breakers for electric dryers and water heaters.

We stock about 155 30 amp breakers from Eaton, Square D, Siemens, GE, Murray, Leviton and ABB.

Match your panel first. A breaker only fits the panel brand and line it is made for: Square D QO (QO230) or Homeline (HOM230), Eaton BR (BR230) or CH (CHF230), Siemens (Q230) or GE (THQL2130). Check the label inside your panel door, or send us a photo and we will match it.
