Product FAQs
5 answersWhat panelboards are compatible with the THHQB22100 circuit breaker?
The THHQB22100 is a bolt-on circuit breaker designed for use in GE A-Series and ReliaGear commercial panelboards. It is not compatible with standard residential Q-Line load centers, which require plug-on breakers like the THQL series.
What is the difference between the THHQB22100 and the THQB22100?
Both are 2-pole, 100A bolt-on circuit breakers with identical physical dimensions, but they have different short-circuit interrupting ratings. The THHQB22100 has a higher 22kAIC rating, while the standard THQB22100 is rated for 10kAIC.
What are the lug torque specifications for the THHQB22100?
For the box lugs on this 100A breaker, the recommended tightening torque depends on the wire size. Use 45 in-lb for 6 to 4 AWG wire, and 50 in-lb for 3 to 1/0 AWG wire. Always verify exact torque requirements on the breaker label before installation.
Can I use aluminum wire with the THHQB22100?
Yes, the box lugs on this breaker are rated for both copper and aluminum conductors. It accepts 6 to 1/0 AWG copper wire or 4 to 1/0 AWG aluminum wire.
Does the THHQB22100 provide GFCI or AFCI protection?
No. This is a standard thermal-magnetic circuit breaker providing overload and short-circuit protection. It does not include Ground Fault Circuit Interrupter (GFCI) or Arc Fault Circuit Interrupter (AFCI) functionality.
