Does Lowes sell Square D?

Yes, Lowes does sell Square D products, although Home Depot is the primary big box retailer for Square D Homeline. At Lowes stores and on Lowes.com, you can find a range of Square D Homeline electrical products including main breaker load centers, main lug panels, Homeline circuit breakers in single-pole, double-pole, GFCI, and AFCI types, as well as accessories like ground bars, filler plates, and panel covers. Lowes typically stocks common residential sizes like 100 amp and 200 amp Homeline panels with 20 to 40 spaces that are suitable for most home panel replacements or upgrades. The availability of the premium Square D QO series at Lowes is more limited in physical stores, as QO is primarily sold through electrical supply houses and Home Depot, but you can often order QO panels and breakers online through Lowes.com for home delivery or store pickup. Lowes also carries Square D safety switches, disconnects, and other Schneider Electric products. If you need a specific Square D QO panel, a commercial NQ or NF panel board, or a large selection of QO breakers, you may find better stock at an electrical distributor like Graybar, City Electric Supply, or at Home Depot. For most common residential needs, Lowes is a viable source for Square D.
