Product FAQs
6 answersWhat panels are compatible with the QO115EPD circuit breaker?
This plug-on breaker is designed exclusively for use in Square D QO load centers and NQ panelboards. It is not compatible with Homeline load centers or panels from other manufacturers.
What is the ground fault trip threshold for the QO115EPD?
This Equipment Protection Device (EPD) features a 30mA ground fault trip threshold. It is designed to protect equipment from low-level faults and is not intended for 5mA Class A personnel protection.
Does the QO115EPD require a neutral connection to function properly?
Yes, this breaker includes a pigtail neutral wire that must be connected directly to the neutral bus bar in the panel for the ground fault sensing circuitry to operate correctly.
What types of applications typically require a 30mA GFEP breaker?
Equipment protection devices (EPD) are commonly used for heat trace cables, snow melting equipment, and dedicated machinery where a standard 5mA GFCI might experience nuisance tripping.
Is there a bolt-on equivalent for the QO115EPD?
Yes, if you are installing in a panelboard that requires bolt-on connections, you will need the QOB115EPD instead of this plug-on QO version.
Can the QO115EPD be used to meet NEC requirements for bathroom or kitchen receptacle circuits?
No. Receptacles in bathrooms and kitchens require 5mA Class A personnel protection. This EPD breaker has a 30mA trip threshold and is strictly rated for equipment protection.
