Product FAQs
7 answersWhich electrical panels are approved for use with this breaker?
This plug-on breaker is UL listed for installation in Square D QO load centers, as well as NQ and legacy NQOD panelboards.
Will the QO115CP fit into a Square D Homeline load center?
No. QO series breakers have a 3/4-inch width per pole and a specific mounting clip. They are not interchangeable with Homeline breakers, which require a 1-inch width per pole.
What does the CP suffix indicate on the QO115CP catalog number?
The CP stands for Consumer Packaging or Commercial Packaging. The breaker itself is a standard QO115 miniature circuit breaker, but it is shipped in a retail blister pack rather than bulk contractor packaging.
What type of wire connections does the QO115CP support?
The breaker features pressure plate terminals designed to accept 14 AWG to 8 AWG copper or aluminum conductors. Ensure proper torque is applied during installation as specified on the breaker label.
How does the Visi-Trip indicator function on this breaker?
When the breaker trips due to an overcurrent or short circuit, the handle snaps to a midpoint position and a bright red indicator flag appears. This allows for rapid identification of the tripped circuit inside a crowded panel.
Can the QO115CP be used in direct current applications?
Yes. While primarily used for 120/240VAC systems with a 10kAIC rating, this breaker is also rated for 48VDC systems with a 5kAIC interrupting capacity.
Is this 15-amp breaker suitable for HVAC equipment and lighting control?
Yes. The QO115CP is HACR rated for use with heating, air conditioning, and refrigeration equipment. It is also Switching Duty (SWD) rated, making it suitable for regular switching of 120V fluorescent lighting loads.
