Product FAQs
5 answersWhich panelboards are compatible with the GHB2100 circuit breaker?
The GHB2100 is designed for use in Eaton and Cutler-Hammer Series C panelboards, as well as Pow-R-Line 2 (PRL2) and Pow-R-Line 3 (PRL3) panelboards. It requires the appropriate twin or single connector kits (such as KPRL series hardware) specific to your panelboard model for installation.
What does the 480Y/277VAC voltage rating on the GHB2100 signify?
This slash rating indicates the breaker is intended strictly for use on solidly grounded Wye systems where the line-to-neutral voltage is 277V and the line-to-line voltage is 480V. It is not approved for use on 480V ungrounded or corner-grounded Delta systems.
What are the terminal torque specifications for the GHB2100 lugs?
Torque requirements for Eaton G-frame breakers vary based on the wire gauge. Standard torque is 20 in-lbs for 10 AWG wire, 40 in-lbs for 8 AWG, and 45 in-lbs for 6 AWG up to 1/0 AWG conductors. Always verify the exact torque values printed on the breaker nameplate prior to termination.
Can the GHB2100 be reverse fed?
Yes, Eaton G-frame molded case circuit breakers, including the GHB2100, are suitable for reverse feed applications.
Is there a difference between the Eaton GHB2100 and the Cutler-Hammer GHB2100?
No, there is no technical difference. Eaton acquired Cutler-Hammer and continues to manufacture these G-frame breakers to the exact same specifications. The breaker you receive may feature either brand name, but the UL listings, physical dimensions, and trip units are identical.

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.
