Providing high-capacity circuit defense, the Square D HOM250EPD is a 50A, 2-pole equipment protection device. It is calibrated with a 30mA Class B ground-fault threshold, ensuring reliable operation for heavy-duty applications requiring higher leakage tolerances. Manufactured exclusively for Square D Homeline load centers, it utilizes a plug-on mounting system and accepts 8-2 AWG conductors. Rated 10kAIC at 120/240VAC, the HACR-rated unit includes a factory-installed pigtail neutral.
HACR Rated, Common Trip, Visual Trip Indicator, RoHS Compliant
Product FAQs
6 answers
Can I install the HOM250EPD in a Square D QO load center?
No. The HOM250EPD is designed exclusively for Square D Homeline load centers. QO load centers require QO series breakers, which have a different mounting design and a 3/4-inch width per pole compared to the 1-inch width of Homeline breakers.
What is the ground fault trip threshold for the HOM250EPD?
This Equipment Protection Device (EPD) features a 30mA Class B ground fault trip threshold. It is designed to protect equipment from damaging line-to-ground faults rather than providing the 5mA Class A protection required for personnel safety.
Does the HOM250EPD require a neutral connection to function properly?
Yes. This breaker includes a factory-installed pigtail neutral wire that must be connected to the neutral bus bar in the load center for the ground fault protection circuitry to operate correctly.
What types of applications typically require a 50A EPD circuit breaker?
A 50A Equipment Protection Device is commonly used for heavy-duty applications that require a higher ground fault leakage tolerance, such as heat trace cables, snow melting equipment, and large well pumps.
Is the HOM250EPD suitable for HVAC equipment?
Yes. The HOM250EPD is HACR rated, meaning it is approved for use with heating, air conditioning, and refrigeration equipment that requires a 50A circuit with equipment-level ground fault protection.
How do I verify the ground fault protection is working on the HOM250EPD?
You should test the ground fault protection monthly using the built-in test button. Pressing the button simulates a fault, and the breaker must trip immediately to confirm the internal safety circuitry is fully operational.
