Description
Built for heavy-duty industrial environments, this 20A G-frame breaker monitors circuits for 30mA ground fault leakage. This equipment-level threshold protects expensive motors and machinery without the frequent interruptions common to 5mA personnel GFCI units. Installation is streamlined for OEM control panels and Eaton Series C enclosures via its unit-mount design.Specifications

Product FAQs
7 answersWhat enclosures or panels is the GHCGFEP1020 compatible with?
This breaker is designed for use in Eaton Series C enclosures and OEM panels. It can also be mounted on a standard 35mm DIN rail using a separate adapter kit.
What is the DIN rail adapter part number for this 1-pole GHC breaker?
To mount this 1-pole breaker on a standard 35mm DIN rail, you will need Eaton adapter kit part number 1225C79G01.
What is the ground fault trip sensitivity for the GHCGFEP1020?
This is a Ground Fault Equipment Protection (GFEP) breaker with a 30 mA trip sensitivity. It is designed to protect equipment from damaging line-to-ground faults rather than for personnel protection.
Can this breaker be used in DC applications?
Yes, the GHCGFEP1020 is rated for 125VDC with an interrupting capacity of 14kAIC, in addition to its standard 277VAC rating.
What is the purpose of the pigtail neutral on this breaker?
The pigtail wire must be connected to the panel neutral bar to power the internal ground fault sensing circuitry.
What wire sizes are accepted by the lugs on this 20A breaker?
The terminals on this breaker accept wire ranging from 14 AWG to 10 AWG.
Is this breaker suitable for personnel protection in wet locations?
No. This is a 30 mA GFEP breaker intended for equipment protection, such as heat trace cables. It does not provide the 5 mA Class A GFCI protection required for personnel safety in wet areas.
