Product FAQs
7 answersWhich panelboards are compatible with the GHB2080 circuit breaker?
The GHB2080 is designed for use in Eaton Pow-R-Line C, Series C, and legacy Westinghouse PRL2 panelboards. It features a bolt-on mounting style specific to the bus structure of these distribution systems.
Can I use the GHB2080 on an ungrounded 480V Delta system?
No. The 480Y/277VAC rating indicates this breaker is strictly for use on solidly grounded Wye systems where the line-to-neutral voltage is 277V. It lacks the full 480V rating required for ungrounded or corner-grounded Delta systems.
Is the GHB2080 suitable for reverse-feed applications?
Yes. Eaton Series C G-frame circuit breakers, including the GHB2080, do not have line or load restrictions and are suitable for reverse-feed installations.
Can this Eaton breaker replace an older Westinghouse GHB2080?
Yes. Eaton acquired the Westinghouse distribution equipment line. Eaton, Cutler-Hammer, and Westinghouse GHB breakers share the exact same physical dimensions and electrical characteristics, making them direct replacements.
What are the lug torque specifications for the GHB2080?
Torque values depend on the installed wire size. For Eaton G-frame breakers, standard torque is 20 in-lbs for 14 to 10 AWG, 40 in-lbs for 8 AWG, and 45 in-lbs for 6 to 1/0 AWG. Always verify against the breaker nameplate prior to installation.
Is the GHB2080 HACR rated?
Yes, Eaton G-frame molded case circuit breakers are HACR rated, meaning they are approved for use with heating, air conditioning, and refrigeration equipment.
Does the 2-pole GHB2080 feature an internal common trip?
Yes. Like all multi-pole Eaton G-frame breakers, it features an internal common trip mechanism. If an overcurrent or short circuit occurs on one pole, both poles will trip simultaneously to safely disconnect the entire circuit.

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.
