Product FAQs
6 answersWhat panelboards are compatible with the THHQB1115AF circuit breaker?
The THHQB1115AF is a bolt-on miniature circuit breaker designed specifically for use in GE A-Series and ReliaGear lighting panelboards.
What is the difference between the THQB1115AF and the THHQB1115AF?
The primary difference is the interrupting rating. The standard THQB1115AF is rated for 10kAIC at 120/240VAC, while the THHQB1115AF features a higher interrupting capacity of 22kAIC for commercial applications requiring a higher fault current rating.
Does the THHQB1115AF provide combination or branch/feeder arc fault protection?
The THHQB1115AF provides Branch/Feeder arc fault protection. In the GE Q-Line nomenclature, models ending in the AF suffix are branch/feeder AFCIs, whereas models ending in AF2 indicate Combination Type AFCIs.
What are the lug torque specifications for wiring the THHQB1115AF?
For the accepted wire sizes, the recommended lug tightening torque is 35 in-lb for 14-10 AWG wire and 40 in-lb for 8 AWG wire.
How is the neutral connection handled on the THHQB1115AF?
This breaker features a pigtail neutral connection. The coiled pigtail wire must be routed and secured directly to the neutral bus bar of the panelboard to ensure the arc fault circuitry functions correctly.
Can the THHQB1115AF be used with aluminum wiring?
Yes, the box lugs accept 12-8 AWG aluminum conductors or 14-8 AWG copper conductors. When terminating aluminum wire, ensure you apply the correct torque and use an appropriate oxide inhibitor compound.
