Product FAQs
6 answersWhat panelboards are compatible with the EGH3050FFG?
This EG-frame breaker is designed for use in Eaton Series G panelboards, Pow-R-Line panelboards, switchboards, and motor control centers. Because it is a unit-mount breaker, it bolts directly to the chassis or mounting pan rather than plugging onto a busbar.
Are the factory lugs on the EGH3050FFG rated for aluminum wire?
Yes, the standard line and load lugs included with this breaker accept both copper and aluminum conductors ranging from 14 AWG to 1/0 AWG. Ensure proper application of joint compound when terminating aluminum wiring to prevent oxidation.
What do the letters FFG indicate in the EGH3050FFG catalog number?
In the Eaton Series G nomenclature, the first F indicates a fixed thermal trip, the second F indicates a fixed magnetic trip, and the G signifies that the breaker comes factory-equipped with standard line and load side lug terminals.
Can the EGH3050FFG replace an EGB3050FFG or EGS3050FFG breaker?
Yes. The EGH3050FFG shares the exact same physical dimensions and EG-frame footprint as the EGB3050FFG and EGS3050FFG. The EGH simply offers a higher interrupting capacity of 65kA at 480V, making it a safe and direct upgrade for systems requiring a higher fault current rating.
Does the EGH3050FFG come with panelboard mounting hardware?
No, this unit-mount breaker includes line and load lugs but does not include the specific mounting brackets or bus connectors required for your panelboard. You will need the appropriate hardware kit designed for your specific Eaton Pow-R-Line panelboard or switchboard chassis.
Can I adjust the trip settings on the EGH3050FFG?
No, this specific breaker features a non-interchangeable thermal-magnetic trip unit with fixed long-time and fixed instantaneous trip settings. If your application requires adjustable trip curves, you will need a breaker equipped with an electronic trip unit.
