What panels are compatible with the THQL2140GF breaker?

This breaker is designed for use in GE PowerMark Gold load centers, GE A-Series panelboards, and ABB ReliaHome load centers.

Are ABB and GE THQL circuit breakers interchangeable?

Yes. ABB acquired GE Industrial Solutions, so THQL breakers branded under either ABB or General Electric belong to the same product line and are fully interchangeable.

How much panel space does this 2-pole breaker require?

The THQL series features a standard 1-inch per pole design. As a 2-pole breaker, it requires two adjacent 1-inch spaces, taking up a total of 2 inches of bus space in the panel.

What level of ground fault protection does the THQL2140GF provide?

This breaker provides Class A 5mA ground fault protection, which is designed for personnel safety in wet or damp locations to meet NEC requirements.

How is the neutral connection made on this GFCI breaker?

The THQL2140GF features a pigtail neutral wire that must be connected directly to the neutral bus bar in the panel to enable proper ground fault detection.

What wire sizes are accepted by the box lugs on this 40A breaker?

The terminal lugs accept 8 AWG to 3 AWG copper or aluminum conductors.
