Product FAQs

6 answers
Can I install the THHQL1120GF in a standard GE PowerMark Gold load center?

Yes, this plug-in breaker is fully compatible with GE PowerMark Gold Load Centers, as well as GE A-Series Panelboards and ABB ReliaHome Load Centers.

What is the difference between the THHQL1120GF and the THQL1120GF?

The THHQL1120GF features a higher interrupting rating of 22kAIC, which is indicated by the HH in the catalog number. The standard THQL1120GF is rated for 10kAIC. The 22kAIC THHQL version can safely replace the 10kAIC version in compatible panels.

How is the neutral connected for this GFCI breaker?

The THHQL1120GF uses a pigtail neutral wire. This wire must be routed and terminated directly to the neutral bus bar in the panel to power the internal ground fault sensing circuitry.

Does this breaker require a specialized plug-on neutral panel?

No. Because it utilizes a standard pigtail neutral wire, it can be installed in older or standard compatible load centers that lack plug-on neutral bus bars.

What class of ground fault protection does the THHQL1120GF provide?

It provides Class A GFCI protection, which trips at a 5mA threshold. This level of protection is designed for personnel safety in locations such as bathrooms, kitchens, and outdoor receptacles.

Does the THHQL1120GF provide combination arc fault (AFCI) protection?

No, this is a dedicated ground fault circuit interrupter (GFCI) with standard thermal magnetic overcurrent protection. It does not include AFCI detection.
