Product FAQs
7 answersHow much panel space does the THQL1150 require?
The THQL1150 is a standard full size breaker that requires one 1-inch space in a compatible load center.
Are GE THQL breakers compatible with ABB ReliaHome load centers?
Yes, GE THQL Q-Line breakers are fully compatible with both legacy GE PowerMark Gold load centers and the newer ABB ReliaHome series panels.
What are the recommended lug torque specifications for the THQL1150?
The box lugs on the THQL1150 should be torqued to 40 in-lb for 8 AWG wire, 45 in-lb for 6 to 4 AWG wire, and 50 in-lb for 3 AWG wire.
Is the THQL1150 circuit breaker HACR rated?
Yes, like all modern UL 489 listed GE Q-Line breakers, the THQL1150 is HACR rated for use with heating, air conditioning, and refrigeration equipment.
Is there a difference between GE THQL and ABB THQL breakers?
No, GE Industrial Solutions was acquired by ABB. The THQL1150 is the exact same Q-Line breaker, though newer stock may feature ABB branding instead of the legacy GE logo.
Can I substitute a THQP breaker for the THQL1150?
THQP breakers are half-inch width variants and only fit in specific GE load centers with specialized bus stabs. The THQL1150 is a standard 1-inch width breaker. They are not universally interchangeable, so you must verify your panel accepts full size THQL breakers.
How does the THQL1150 indicate a tripped condition?
The breaker features a three-position handle. When a fault is detected, the handle moves to a center tripped position between ON and OFF, making it easy to identify which circuit requires attention.
