Eaton GHC1030 – Frequently Asked Questions

1) Will a GHC1030 fit the space in my panelboard?
The breaker measures 1 in width, 2.63 in depth and 4.88 in height, so it takes a single 1-inch pole space. It is a G-frame molded case breaker, meaning the enclosure or panelboard interior has to be built to accept G-frame devices, not a residential load center bus.
2) Can I use a single-pole GHC on a 480V two-pole circuit?
No. This is a single-pole device rated 277 Vac, so it protects one ungrounded conductor referenced to neutral. A 480V line-to-line load needs a two-pole or three-pole breaker rated for 480 Vac. Using this one across two phases is outside its voltage rating.
3) Can the trip setting on the Eaton GHC circuit breaker be adjusted?
No. The GHC uses fixed thermal and fixed magnetic trip elements, both factory set. There is no adjustable instantaneous dial and no interchangeable trip unit, so the 30 amp rating is what you get. If the job requires field-adjustable protection, specify an adjustable-trip or electronic-trip breaker instead.
4) Does the GHC1030 come as a complete breaker or do I need to order a trip unit separately?
It ships as a complete breaker, factory assembled with its trip elements in place. Nothing else has to be ordered to make it a functioning device. Mounting hardware, connectors or accessories specific to your panelboard are separate items.
5) Is the Eaton Series C GHC breaker UL Listed for commercial work?
UL Listed, which is what inspectors and institutional specs typically call for on commercial and industrial panelboard overcurrent protection. It is part of Eaton's Series C platform, breaker type GHC.
6) Can the GHC1030 be used on a DC circuit?
Yes, up to 125 Vdc as a single-pole device. Its AC ratings are 277 Vac at 50/60 Hz with 14 kAIC interrupting capacity; the published interrupting figure is tied to the 277 Vac rating.
