Product FAQs
7 answersCan I install the HOM140 in a Square D QO load center?
No. Homeline (HOM) breakers feature a 1-inch format and are only compatible with Square D Homeline load centers and CSED devices. They will not fit onto the bus bars of a QO panel.
Is the HOM140 UL listed for use in competitor panels?
No. The HOM140 is UL listed exclusively for use in Square D Homeline load centers. Installing it in panels from other manufacturers violates the UL listing and compromises safety.
What is the terminal torque specification for the HOM140?
The box lug terminals on the HOM140 should be torqued to 40.7 lb-in (4.6 N.m) when using 8 to 2 AWG copper or aluminum wire.
How many panel spaces does the HOM140 require?
As a standard 1-pole Homeline breaker, the HOM140 requires one full 1-inch space in the load center.
What is the difference between the HOM140 and HOM140CP?
There is no functional or physical difference between the two. The HOM140CP is simply a packaging variant (often retail blister pack or bulk barcoded) of the standard HOM140 circuit breaker.
Is the HOM140 suitable for HVAC applications?
Yes, the HOM140 is HACR rated, making it approved for use with heating, air conditioning, and refrigeration equipment that requires a 40A, 120V supply.
What are typical applications for a 40A 1-pole breaker?
A 40A 1-pole breaker provides 120V power and is typically used for dedicated high-draw 120V circuits, such as specialized lighting loads, specific RV receptacles, or heavy-duty 120V equipment.
