Description
Providing a 30mA ground fault threshold, this 20-amp breaker focuses on equipment-level protection for dedicated circuits. It prevents damage to sensitive gear without nuisance tripping at the lower 5mA personnel limit. Designed as a modern upgrade, this unit replaces the legacy GFEP120 model. It installs into standard Eaton Type BR load centers using a secure plug-on connection and a pigtail neutral wire. The short-body design saves gutter space while maintaining a 10kAIC rating.Specifications

Product FAQs
6 answersWhat type of panel is required for the BRN120EP?
This breaker installs into standard Eaton Type BR load centers. It requires a single 1-inch space and utilizes a standard plug-on connection.
Does this breaker require a panel with a plug-on neutral bar?
No. The BRN120EP features a pigtail neutral wire, allowing it to be installed in both legacy and modern Type BR load centers regardless of whether they have a plug-on neutral chassis.
What is the trip threshold for the ground fault protection on this breaker?
The BRN120EP operates with a 30mA ground fault threshold. This equipment-level protection prevents damage to sensitive gear, such as heat trace cables, without the nuisance tripping associated with 5mA personnel protection breakers.
What legacy Cutler-Hammer breaker does the BRN120EP replace?
The BRN120EP serves as the direct replacement for the discontinued Eaton / Cutler-Hammer GFEP120 circuit breaker.
How is the ground fault circuit completed during installation?
The breaker features a pigtail neutral wire that must be routed and terminated directly at the panel's neutral bus bar. The load neutral wire is then terminated on the breaker itself to enable the ground fault sensing circuitry.
Is the BRN120EP suitable for personnel protection on general-purpose receptacles?
No. This breaker provides 30mA Ground Fault Equipment Protection (GFEP). It does not provide the 5mA Class A personnel protection (GFCI) required by the NEC for locations like bathrooms, kitchens, or outdoor outlets.
