Product FAQs
7 answersWhich panelboards are compatible with the THHQB22020 circuit breaker?
The THHQB22020 is a bolt-on Q-Line breaker designed for use in GE and ABB A-Series panelboards, AQ lighting panels, and ReliaGear panelboards.
What is the difference between GE THHQB and THQB circuit breakers?
The primary difference is the interrupting capacity. THHQB breakers are high-interrupting models rated at 22kAIC, whereas standard THQB breakers are rated at 10kAIC. Both series share the exact same physical dimensions and bolt-on mounting style.
What wire sizes are accepted by the lugs on the THHQB22020?
The load side box lugs on this 20-amp breaker accommodate 14 AWG to 8 AWG copper wire, or 12 AWG to 8 AWG aluminum wire.
How much panel space does the THHQB22020 require?
As a standard Q-Line breaker, it measures 1 inch wide per pole. Because this is a 2-pole breaker, it requires 2 inches of total width on the panelboard bus.
Why might my THHQB22020 breaker arrive with ABB branding instead of General Electric?
ABB acquired GE Industrial Solutions in 2018. Depending on the manufacturing date, Q-Line breakers like the THHQB22020 may be branded as either GE or ABB. They are identical in form, fit, and function.
Is the THHQB22020 suitable for HVAC equipment?
Yes, this breaker is HACR rated, making it suitable for protecting heating, air conditioning, and refrigeration equipment circuits that require a 20-amp, 2-pole breaker.
Can the THHQB22020 be reverse fed?
Yes, GE Q-Line thermal-magnetic circuit breakers are suitable for reverse feed applications.
