Your cart is empty.The Square D by Schneider Electric QO Qwik-Gard 40 Amp Two-Pole GFCI Circuit Breaker is intended for protection of entire branch circuits where damp-location shock hazards may exist, providing overload and short-circuit protection of your electrical system. The ANSI-certified and UL-listed unit is rated for 120/240 VAC and 10,000 AIR. All QO circuit breakers are equipped with the exclusive Visi-Trip indicator. When a QO Visi-Trip circuit breaker trips, the handle snaps to a midpoint position between "OFF" and "ON" and a highly visible, red indicator easily identifies the tripped breaker. This enables you to easily distinguish which breaker has tripped in a load center that may contain up to 42 different circuit breakers. QO circuit breakers have features no other manufacturer can offer. They come in many different sizes and can meet the needs of virtually every function in your home or business. These types of quality, industry exclusive products keep the Square D brand ahead of the competition and are builders' and electrical contractors' first choice in electrical protection.

I got this as a replacement for a 25yo electric range breaker in order to add GFCI. Initially it kept tripping instantly when turning on. I did learn that these GFCI breakers only work with 4-wire outlets and cords, which luckily I had. However when the cord was installed into the range the instructions on the back of the range were not followed and the ground was still bonded to the neutral. Once I removed the bond for ground/neutral per range instructions the breaker worked fine.

I don't know why my local shop couldn't order this for me, but they said they couldn't—so this availability online was critical to finishing my project. It's the right breaker for running my steam generator for indoor spa, installed perfectly.

I’m a licensed electrician and built my house. When doing the garage I added a EV 40amp charging plug. I used 6 guage at 15ft from panel. So if you plan on doing the same as me use 6-8 guage wire, 40 amp receptacle and the gfci 40 amp breaker. Per NEC code garage plug need to be GFCI for EV chargers. I don’t have a ev car yet but I can hook a welder if needed also.

The only issue that you may have with this breaker is that you will need to install it at the top of the breaker panel. The attached ground wire is short. In order to reach the grounding bar at the top of your panel, you will need to put this breaker at the top in order to reach the bar with the short wire. That ground wire is #8 cable. Pretty still and fat. I don't think you would want to splice something onto it to reach the grounding bar in your box.

Bought these for a job I needed to complete. Cheaper then anywhere else I could find and an exact replacement for what I needed.
