Product FAQs
8 answers
What is the difference between the QO115CAFI and the QO115VHCAFI?
The QO115VHCAFI has a higher interrupting rating of 22kAIC, indicated by the VH in the catalog number. The standard QO115CAFI has a 10kAIC rating.
What is the difference between the QO115VHCAFI and the QO115VHPCAFI?
The QO115VHCAFI features a pigtail neutral wire that connects to the panel's neutral bar. The QO115VHPCAFI is a Plug-on Neutral (PoN) breaker that connects directly to the neutral bar without a pigtail.
Can I install this QO breaker in a Homeline load center?
No. Square D QO circuit breakers have a 3/4-inch width per pole and are not interchangeable with Homeline breakers, which require a 1-inch space per pole.
Which panels are compatible with the QO115VHCAFI?
This breaker is designed for plug-on installation in Square D QO load centers and NQ panelboards.
What type of protection does a Combination Arc Fault (CAFI) breaker provide?
A CAFI breaker protects against both parallel and series arcing faults in branch circuit wiring, helping to prevent electrical fires, in addition to standard overload and short-circuit protection.
How is the neutral connection made on the QO115VHCAFI?
This breaker includes a pigtail neutral wire that must be manually routed and terminated at the neutral bar in the load center or panelboard.
What wire sizes are accepted by the terminals on this breaker?
The pressure plate terminals accept 14 AWG to 8 AWG copper wire, or 12 AWG to 8 AWG aluminum wire.
What does the 22kAIC rating mean for this breaker?
The 22kAIC (kilo-Amperes Interrupting Capacity) rating indicates the maximum fault current the breaker can safely interrupt without sustaining damage. This is higher than the 10kAIC rating found on standard residential breakers.
