Guide

Before you buy a breaker

  1. 1

    Match the panel

    Find the brand and series on the label inside the panel door. Homeline and QO are both Square D, and they do not interchange.

  2. 2

    Match the wire

    The breaker protects the wire. For copper: 14 AWG on 15 A, 12 AWG on 20 A, 10 AWG on 30 A.

  3. 3

    Protection

    Standard, AFCI (arc fault), GFCI (ground fault) or dual function. Your local code says which circuits need which.

  4. 4

    Tandem and quad

    Two circuits in one space, only in the slots the panel label allows.
