20 Amp Circuit Breakers

20 amp breakers are used on 12 AWG copper circuits (NEC 240.4(D)). Kitchen countertop, bathroom and laundry outlets all need 20 amp circuits (NEC 210.11(C)).

We stock about 335 20 amp breakers from Eaton, Square D, Siemens, GE, Leviton, Murray and ABB.

Match your panel first. A breaker only fits the panel brand and line it is made for: Square D QO (QO120) or Homeline (HOM120), Eaton BR (BR120) or CH (CHF120), Siemens (Q120) or GE (THQL1120). Check the label inside your panel door, or send us a photo and we will match it.

Kitchen, bathroom and outdoor circuits usually need GFCI protection; most living areas need arc fault or dual function breakers.
