Product FAQs
7 answersCan I install the QO115 in a Square D Homeline load center?
No. Square D QO breakers feature a 3/4-inch width per pole, while Homeline panels require 1-inch format breakers. You must use Homeline breakers for Homeline load centers.
Is this breaker compatible with older NQOD panelboards?
Yes. The QO115 is backward compatible with legacy NQO and NQOD panelboards, in addition to current NQ panelboards and standard QO load centers.
Is the QO115 HACR and SWD rated?
Yes. This breaker is HACR rated for use with heating, air conditioning, and refrigeration equipment. It is also SWD (Switching Duty) rated, meaning it can safely be used on a regular basis to switch 120V fluorescent lighting loads on and off.
How do I know if the QO115 has tripped?
This breaker features the Square D Visi-Trip indicator. When an overload or short circuit causes the breaker to trip, the handle shifts to a midpoint position and a highly visible red flag appears in the indicator window.
What is the difference between the QO115 and QO115CP?
There is no functional difference. The CP suffix stands for commercial packaging, meaning the breaker is shipped in a retail blister pack. The circuit breaker inside the package is an identical QO115.
What is the bolt-on equivalent for the QO115?
If your panelboard requires a bolt-on connection instead of a plug-on connection, the direct equivalent model is the QOB115.
Is there a tandem version of this breaker to save panel space?
Yes. If your load center bus bar is designed to accept tandem breakers, you can use the QO1515. It provides two independent 15A single-pole circuits while only occupying one standard 3/4-inch space.
