Product FAQs

6 answers
What electrical panels are compatible with the THHQL1120GFT?

This Q-Line breaker is designed for use in GE PowerMark Gold load centers, GE A-Series panelboards, and ABB ReliaHome load centers that accept 1-inch THQL frame plug-in breakers.

What is the difference between the THQL1120GFT and the THHQL1120GFT?

The difference is the short circuit interrupting rating. The THQL1120GFT is rated for 10kAIC, while the THHQL1120GFT has a higher interrupting rating of 22kAIC. Both are 20-amp, single-pole GFCI breakers with self-test capabilities.

What does the GFT suffix mean on this GE circuit breaker?

The GFT indicates that it is a Ground Fault Circuit Interrupter (GFCI) equipped with a self-test feature. This internal mechanism periodically tests the ground fault protection to ensure the breaker is functioning correctly and will trip in the event of a fault.

Does the THHQL1120GFT use a pigtail or a plug-on neutral connection?

This specific model features a pigtail neutral connection. The coiled white wire must be connected directly to the neutral bus bar in your panel. If your panel requires a plug-on neutral connection, you will need the THHQL1120PGFT instead.

How much space does the THHQL1120GFT require in a load center?

As a standard 1-pole Q-Line breaker, it requires one full 1-inch space in the panel.

Is the THHQL1120GFT HACR rated?

Yes, this breaker is UL listed for HACR (Heating, Air Conditioning, and Refrigeration) applications, making it suitable for protecting dedicated HVAC circuits.
