Product FAQs
6 answersWhich panelboards are compatible with the THQB2170 circuit breaker?
The THQB2170 is designed exclusively for use in GE A-Series panelboards, specifically AQ lighting and distribution panels. It utilizes a bolt-on connection and will not fit in standard residential load centers that require plug-in breakers.
What is the difference between the GE THQB2170 and the THHQB2170?
Both are 70A, 2-pole, bolt-on circuit breakers for GE A-Series panels. The difference is their interrupting capacity. The THQB2170 has a 10kAIC rating, while the THHQB2170 features a higher 22kAIC rating.
Can I substitute a THQL breaker for a THQB breaker?
No. While both are part of the GE Q-Line family, THQB breakers feature a bolt-on mounting style for commercial A-Series panelboards. THQL breakers are plug-in devices designed for standard residential load centers and cannot be bolted to the panel bus.
What are the box lug torque specifications for the THQB2170?
The recommended lug tightening torque depends on the wire gauge. Torque 6 AWG to 4 AWG wire to 45 in-lb, and 3 AWG to 1/0 AWG wire to 50 in-lb.
How much panel space does the THQB2170 require?
As a 2-pole Q-Line breaker, the THQB2170 requires two 1-inch spaces, occupying a total of 2 inches of width on the panel bus.
Does the THQB2170 provide ground fault or arc fault protection?
No. The THQB2170 is a standard thermal-magnetic circuit breaker providing long-time and instantaneous (LI) trip functions for overload and short-circuit protection. It does not include GFCI or AFCI capabilities.
