Product FAQs
7 answersWhat is the direct 10kAIC replacement for the TQL32020?
If your application requires a 10kA interrupting capacity, you can upgrade to the THQL32020. The THQL32020 is the modern equivalent that shares the same physical dimensions and plug-on mounting but offers a higher short-circuit rating.
Which panelboards are compatible with the TQL32020 circuit breaker?
This plug-on breaker is designed for use in older GE PowerMark Gold load centers, GE A-Series panelboards, and GE lighting panels that accept 1-inch per pole Q-Line breakers.
What wire sizes and materials are accepted by the box lugs on this breaker?
The box lug terminals accept 14 to 8 AWG copper wire or 12 to 8 AWG aluminum wire.
What does the LI trip function code mean for this breaker?
The LI code indicates a thermal-magnetic trip unit. The thermal element provides long-time (L) protection against overloads, while the magnetic element provides instantaneous (I) protection against short circuits.
Can I use a THQP half-inch breaker in place of this TQL breaker?
No. The TQL32020 is a full-size breaker requiring 1 inch of space per pole, totaling 3 inches of panel space. THQP breakers are half-inch width and only fit in specific panel slots designed for tandem configurations.
What is the interrupting capacity of the TQL32020?
The TQL32020 is rated for a 5kA interrupting capacity at 120/240V AC. If your panel or local code requires a 10kA rating, you must cross-reference and install the THQL32020 substitute.
Is there a 65kAIC version of this 20A 3-pole breaker?
Yes. For industrial or commercial applications requiring maximum short-circuit protection, the TXQL32020 offers a 65kA interrupting capacity while maintaining the same plug-on Q-Line form factor.
