Great product

 Would Recommend

This circuit breaker was purchased for the purpose of installing by an EV charger in my garage. Combined with 6 gauge wiring, and an electrical box and plate cover, It’s doing its job perfectly - my car charges at the fastest speeds possible without going to a supercharger!

Great product

 Would Recommend

This breaker was purchased to replace a breaker that had burned out, maybe due to a surge, although not sure. It has been installed for a week now and works as expected.

The plastic breaker handle broken completely off

Received the breaker with the plastic breaker handle broken completely off. This is a critical part of the breaker, making it unusable right out of the box. Very disappointing, especially for a premium Square D QO breaker.
