Questions & Answers

Will this product work properly in a 12 volt DC APPLICATION? I have a DC battery Bank and I'd like protect a 20A dc pump

DC application
Asked by: Gtg
I would not suggest using this for a DC application, DC has VERY different electrical properties. Most AC circuit breakers rely on the zero-crossing voltage of the AC sine wave to be able to successfully break a circuit without an arc over, DC voltage does not have this property and thus has much larger arcs, this would not likely hold up to that arcing over time. You would be best off buying an appropriate DC circuit breaker or fuse to protect your pump and battery bank.

Will these work with an old panel?

Asked by: rf540
If it's a QO type, Square D panel, yes it should work, my panel dates from the late 1970's and it fits just fine.

Hello. I am not sure the 20 amp single-pole circuit breaker is 'QO' or 'Homeline' on the Square D panel because it isn't listed on the label. Are the 'QO 20 Amp Single-Pole Circuit Breaker' and 'Homeline 20 Amp Single-Pole Circuit Breaker' interchangeable? If yes, which one is better? Thank you.
Asked by: Josephine
Hello, Homeline and QO circuit breakers are not interchangeable. The QO breaker has the exclusive red visi trip window. You may find a part number on the door of your load center. It will state HOM or QO. Regards, Customer Care Center
