Panel & Breaker Basics

Match breakers to the panel brand and series — a Square D QO breaker does not belong in a Homeline panel, and no tandem belongs in a full panel. Main lug versus main breaker depends on service versus subpanel use; subpanels need isolated neutrals, with grounds bonded at the first disconnect only. For generator interlocks and transfer switches, confirm the panel model number before ordering — one letter difference changes the kit.

Pro Tips

  • Breakers must match panel brand and series — QO is not Homeline
  • 200A main-breaker panels for new services and solar-ready busbars
  • Transfer switch or interlock — never backfeed a panel
