Product FAQs
10 answersWhat panelboards are compatible with the GHB1080 circuit breaker?
The GHB1080 is designed for use in Eaton Pow-R-Line C panelboards and standard Series C panelboards. It features a bolt-on mounting configuration that attaches directly to the panelboard bus.
What are the recommended torque specifications for the load lugs on the GHB1080?
For the factory-installed lugs accepting #10 to 1/0 AWG wire, the required torque depends on the wire size: 20 lb-in for #10 AWG, 40 lb-in for #8 AWG, and 45 lb-in for #6 to 1/0 AWG. Always verify with the breaker nameplate before terminating.
Can I use the Eaton GHB1080 to replace an older Westinghouse or Cutler-Hammer GHB1080?
Yes. Eaton acquired both Cutler-Hammer and the distribution equipment division of Westinghouse. The current Eaton GHB1080 is the direct, exact replacement for legacy Westinghouse and Cutler-Hammer breakers with the same catalog number.
Is the GHB1080 rated for use in direct current (DC) systems?
Yes, this breaker is rated for 125VDC applications and provides a 14kA interrupting capacity (AIC) at that voltage.
Does the GHB1080 provide ground fault (GFCI) or equipment protection (EPD)?
No. This is a standard thermal-magnetic breaker equipped with fixed long-time and instantaneous (LI) trip functions for overload and short-circuit protection. It does not include ground fault circuitry.
Does the GHB1080 mount to a standard 35mm DIN rail?
No. The GHB1080 is a G-frame bolt-on circuit breaker designed specifically to bolt directly to the busbar of compatible Eaton commercial panelboards. It is not DIN rail mountable.
Can the GHB1080 be reverse fed?
Yes, Eaton G-frame circuit breakers, including the GHB1080, are suitable for reverse feed applications.
Are the lugs on the GHB1080 rated for aluminum wire?
Yes, the standard pressure lugs provided with this breaker are dual-rated for both copper and aluminum conductors within the #10 to 1/0 AWG range.
Is the GHB1080 HACR rated for HVAC applications?
Yes, Eaton G-frame breakers like the GHB1080 carry an HACR rating, making them suitable for use with heating, air conditioning, and refrigeration equipment.
Can the GHB1080 be used as a switch for fluorescent lighting?
No. Only the 15A and 20A single-pole GHB breakers carry the SWD (Switching Duty) rating for fluorescent lighting applications. The 80A GHB1080 is not SWD rated.

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.

- MWMARK W.Verified BuyerReviewingEaton / Cutler-Hammer GHB1020 - 20A 1 Pole Molded Case Circuit BreakerRated 3 out of 5 stars7/21/26Good 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.
