Product FAQs

8 answers
Can I use the GHC2030 in place of a GHB2030?

No. While they share the same G-frame electrical ratings and trip curves, their mounting styles differ. The GHB2030 is a bolt-on breaker for Eaton panelboards, whereas the GHC2030 is a cable-in/cable-out (feed-thru) unit designed for base, OEM panel, or DIN rail mounting.

Can the GHC2030 be mounted on a standard DIN rail?

Yes, it can be mounted to a DIN rail by using the Eaton G-frame adapter kit. For this 2-pole breaker, you will need adapter part number 1225C79G01.

What is the recommended terminal torque for the GHC2030?

Torque specifications depend on the wire size being used. Tighten to 20 lb-in for 14-10 AWG, 40 lb-in for 8 AWG, 45 lb-in for 6-4 AWG, and 50 lb-in for 3-1/0 AWG conductors.

Is it safe to use the GHC2030 on a 480V delta system?

No. The GHC2030 has a 480Y/277VAC slash rating. It is strictly designed for solid-grounded wye systems where the voltage to ground does not exceed 277V. It must not be applied to 480V ungrounded or corner-grounded delta systems.

How does system voltage affect the interrupting capacity of the GHC2030?

The interrupting rating (AIC) varies based on the operating voltage. It delivers a maximum of 65kAIC at 240VAC, but this drops to 14kAIC when used on 480Y/277VAC or 125/250VDC systems.

Are the lugs on the GHC2030 rated for aluminum wire?

Yes, the standard factory lugs are dual-rated for Copper (Cu) and Aluminum (Al) wire, accommodating wire gauges from 10 AWG up to 1/0 AWG.

What enclosures and panels are compatible with this breaker?

The GHC2030 is designed for unit mounting in Eaton Series C enclosures or custom OEM control panels. Because of its feed-thru design, it is frequently used as a main or sub-breaker in standalone machinery panels rather than traditional lighting panelboards.

Is the trip unit on the GHC2030 adjustable?

No. This breaker features a thermal magnetic trip unit with fixed long-time (L) and instantaneous (I) settings. The thermal elements are calibrated for standard 40 degrees Celsius environments and cannot be adjusted in the field.
