Product FAQs
5 answersWhat load centers are compatible with the THHQL1120PDF?
This breaker is designed exclusively for GE PowerMark Gold Plug-on Neutral and ABB ReliaHome Plug-on Neutral load centers. It cannot be used in standard panels because it lacks a neutral pigtail wire and requires a built-in plug-on neutral bus.
What does the PDF suffix in the catalog number indicate?
In GE and ABB Q-Line nomenclature, the PDF suffix stands for Plug-on Dual Function. This indicates the breaker features a plug-on neutral connection and provides both AFCI and GFCI protection.
What is the difference between the THQL1120PDF and THHQL1120PDF?
The difference is the short circuit interrupting rating. The THQL1120PDF is rated for 10kAIC, while the THHQL1120PDF has a higher interrupting capacity of 22kAIC.
How does the plug-on neutral design change the installation process?
The plug-on neutral connection eliminates the need to route and terminate a separate neutral pigtail wire to the panel bus bar. The breaker connects directly to the neutral bus when seated, which saves gutter space and reduces wiring time.
What type of protection does a dual function breaker provide?
Dual function breakers combine Arc Fault Circuit Interrupter (AFCI) and Ground Fault Circuit Interrupter (GFCI) technology in a single device. This provides protection against electrical fires caused by arcing faults and shock hazards caused by ground faults.
