Residential Circuit Breakers




Thermal Magnetic Circuit Breakers

 

Choose 1" THQL circuit breakers or ½'’ per pole Tandem and Quad circuit breakers. Both are superior products and because the compact size Tandems and Quads make the most of available panel space, you can install smaller load centers to save money and space in both new installations and service upgrades.
