Product FAQs
6 answersWhich load centers are compatible with the THQDL21125 breaker?
This breaker is specifically designed for installation in GE PowerMark Gold and GE PowerMark Plus load centers. Check your panel's wiring diagram to confirm support for THQDL frame types.
Can the THQDL21125 be used as a main breaker?
Yes. With its 125A capacity and feed-thru connection design, the THQDL21125 is frequently utilized as a main breaker or a large feeder in compatible GE residential and light commercial panels.
Is the THQDL frame interchangeable with standard THQL branch breakers?
No. While both belong to the GE Q-Line family, THQDL breakers are designed for 125A to 200A applications and utilize a feed-thru connection. They require specific main breaker or sub-feed mounting positions and will not fit into standard branch slots intended for lower-amperage THQL breakers.
What is the accepted wire gauge for the THQDL21125 lugs?
The factory-installed lugs accept 1/0 AWG to 250 kcmil copper or aluminum conductors. Ensure proper torque is applied during installation as specified on the breaker label.
What applications require the 22kAIC rating of the THQDL21125?
The 22kAIC at 240V interrupting rating is often required for service entrance equipment or panels located close to a utility transformer, where available fault currents exceed the standard 10kAIC limit of typical residential breakers.
How does the LI trip function operate on this breaker?
The thermal-magnetic trip unit features fixed Long-Time (L) and Instantaneous (I) functions. The thermal element responds to sustained overloads by heating up and tripping the breaker, while the magnetic element trips instantly in the event of a high-current short circuit.
