Product FAQs
8 answersWhat electrical panels are compatible with the Eaton CHQ215?
The CHQ215 is UL-classified specifically for installation in Square D QO load centers. It will not fit standard Eaton panels.
Can I use the CHQ215 in a Square D Homeline panel?
No. Square D QO and Homeline panels utilize completely different busbar designs. The CHQ series is only classified for QO load centers.
Which Square D circuit breaker does the Eaton CHQ215 replace?
The CHQ215 serves as a direct, UL-classified replacement for the Square D QO215 two-pole circuit breaker.
How much panel space does the CHQ215 require?
As a two-pole breaker with a 3/4-inch width per pole, it requires two adjacent 3/4-inch spaces, taking up 1.5 inches of total space on the busbar.
Does the CHQ215 feature a common trip mechanism?
Yes, it includes an internal common trip mechanism that ensures both poles open simultaneously if an overload or short circuit is detected on either leg.
Is it code compliant to use an Eaton breaker in a Square D panel?
Yes, the Eaton CHQ series is extensively tested and UL-classified as a direct replacement for Square D QO breakers, making it fully compliant with National Electrical Code requirements for these specific panels.
Can I terminate two wires under a single lug on the CHQ215?
Yes, the box lugs are rated to accept either a single 14-8 AWG wire or two 14-10 AWG wires. This dual-wire capability applies to both copper and aluminum conductors.
What do the long-time and instantaneous trip functions do?
The long-time function provides a delayed trip to protect against sustained overloads, while the instantaneous function immediately opens the circuit during a severe short circuit.
