Product FAQs
8 answersWhat is the difference between GE THQP and THQL circuit breakers?
THQL breakers are standard 1-inch wide plug-in breakers, while THQP breakers are 1/2-inch wide slim or half-size breakers designed to save space. The THQP150 requires a load center specifically designed to accept half-inch breakers.
Can I install the THQP150 in any GE load center?
No. While it fits many GE Q-Line and PowerMark Gold load centers, your specific panel must be designed to accept half-inch THQP breakers. Check the wiring diagram on your panel door to confirm THQP compatibility and approved slot locations.
How does the THQP150 mount into the panel?
The THQP150 uses a plug-in connection. Because it is a 1/2-inch breaker, it mounts onto specialized bus stabs in compatible GE load centers, allowing two THQP breakers to fit in the space of one standard 1-inch THQL breaker.
What wire sizes are compatible with the box lugs on the THQP150?
The box lugs on this 50A breaker accept 8 AWG to 4 AWG copper or aluminum wire.
Can the THQP150 be used as a replacement for UBITB150 breakers?
Yes, the GE THQP150 is a direct cross-reference substitute for UBITB150 circuit breakers in compatible load centers.
Does the THQP150 feature a trip-free mechanism?
Yes, it features a trip-free mechanism, meaning the breaker will trip internally even if the handle is held in the ON position during an overload or short circuit.
Is the THQP150 HACR rated?
Yes, this breaker is HACR rated, making it suitable for use with heating, air conditioning, and refrigeration equipment that requires this specific rating.
Can the THQP150 be reverse fed?
Yes, this thermal magnetic breaker supports reverse feed wiring, allowing it to be used in applications where power is fed from the load side.
