Product FAQs
7 answersWhat panelboards are compatible with the THHQB2170 circuit breaker?
The THHQB2170 is a bolt-on Q-Line breaker designed specifically for use in GE A-Series panelboards and GE AQ lighting panels.
Can the THHQB2170 be installed in a standard GE residential load center?
No. The THHQB2170 is a bolt-on breaker designed for commercial panelboards. Standard GE residential load centers require plug-in Q-Line breakers, such as the THQL series.
What is the difference between GE THHQB and THQB circuit breakers?
The H in THHQB indicates a higher interrupting capacity. The THHQB2170 is rated at 22kAIC at 240V, whereas the standard THQB equivalent is rated at 10kAIC. Both share the same 1-inch per pole bolt-on physical footprint.
Can I use the THHQB2170 to replace a THQB2170?
Yes. The THHQB2170 has the exact same physical dimensions and bolt-on mounting configuration as the THQB2170, but offers a higher 22kAIC interrupting rating, making it a safe and direct upgrade.
What wire sizes and materials are accepted by the THHQB2170 terminals?
The box lugs on this breaker accept 6 AWG to 1/0 AWG copper (Cu) conductors, and 4 AWG to 1/0 AWG aluminum (Al) conductors.
Does the THHQB2170 require a specific mounting hardware kit?
No additional mounting kits are required. As a bolt-on breaker, it fastens directly to the busbar connections inside compatible GE A-Series and AQ lighting panels.
How does the thermal-magnetic trip unit function on the THHQB2170?
The fixed LI (Long-Time, Instantaneous) trip unit uses a bimetallic strip for thermal overload protection and an electromagnetic assembly to trip instantaneously during short-circuit events.
