Product FAQs
8 answersWhich load centers are compatible with the THQL1120GFEP2 breaker?
This 1-inch plug-in breaker is designed for use in GE PowerMark Gold and ABB ReliaHome load centers that accept THQL series breakers.
What is the ground fault trip threshold for this breaker?
The THQL1120GFEP2 features a 30mA ground fault equipment protection trip threshold. It is designed to protect machinery and equipment from damage rather than providing 5mA personnel protection.
Does this breaker require a pigtail connection for the neutral?
Yes, this model includes a factory-installed pigtail wire that must be connected to the panel neutral bar to enable accurate ground fault monitoring.
Is the ABB THQL1120GFEP2 the same as the GE THQL1120GFEP2?
Yes. ABB acquired GE Industrial Solutions, so breakers previously branded as General Electric are now manufactured by ABB under the exact same THQL catalog numbers.
Can I use this 30mA GFEP breaker for bathroom or kitchen receptacles?
No. The National Electrical Code requires 5mA Class A GFCI protection for personnel in areas like bathrooms, kitchens, and pools. This 30mA breaker is strictly for equipment protection to prevent nuisance tripping on dedicated machinery.
How much panel space does the THQL1120GFEP2 require?
As a standard THQL series breaker, it requires one full 1-inch space in the load center.
Can I install this breaker in a panel that specifies THQP breakers?
THQL breakers are 1-inch wide, whereas THQP breakers are half-inch wide. You can install a THQL breaker in a THQP-compatible GE panel only if the panel has standard 1-inch spaces available and the internal labeling explicitly permits THQL types.
What does the GFEP designation mean on this circuit breaker?
GFEP stands for Ground Fault Equipment Protection. It indicates the breaker is engineered to detect electrical current leakage and shut off power to protect sensitive electronics, heat tracing, or machinery from damage.
