Product FAQs

6 answers
Can I install the Eaton GHB1050 in a standard residential load center?

No. The GHB1050 is a bolt-on molded case circuit breaker designed specifically for commercial Eaton Pow-R-Line C and Series C panelboards. It is not compatible with standard plug-on residential load centers.

Is the GHB1050 circuit breaker HACR rated?

Yes, all Eaton G-frame circuit breakers, including the GHB1050, are HACR rated for use with heating, air conditioning, and refrigeration equipment.

Can the Eaton GHB1050 be reverse fed?

Yes, Eaton G-frame molded case circuit breakers are suitable for reverse feed applications.

Is the 50A GHB1050 rated for switching duty (SWD)?

No. In the Eaton GHB series, only the 15A and 20A single-pole breakers carry the SWD rating for switching fluorescent lighting loads.

What are the terminal torque specifications for the GHB1050?

The required lug torque depends on the wire gauge. For 14 to 10 AWG wire, torque to 20 in-lb. For 8 AWG, use 40 in-lb. For 6 AWG through 1/0 AWG, torque to 45 in-lb.

Will the Eaton GHB1050 replace an older Westinghouse GHB1050?

Yes. Eaton acquired the Westinghouse distribution equipment line. The Eaton GHB1050 is the direct replacement for legacy Westinghouse and Cutler-Hammer breakers sharing the same catalog number.

    Used model

    Breaker ohm tested out fine and currently working on load test with a longer term battery charger. So far so good. Packaged very well no visible damages during shipping. Even received a follow up call from customer that I missed.

    Good Product, but Disappointed With the Service

    Good product, but I was disappointed with the service. I accidentally placed two separate orders and ended up paying freight on both. I had requested that they combine the orders, and had that been done with the freight waived, it would have saved me money.

    Other than that, everything was good. I’m just disappointed that no one communicated this to me.
