  • why would my electric furnace have 2 breaker switches

    I actually see two potential issues here. When you say two breaker switches, do you mean two separate single-unit breaker switches? Or do you count a double-slot two-pole switch with a handle tie between the two switches as one unit and call it one switch? Either way, it is either rather unusual or simply wrong setup.
