Product FAQs
6 answersWhat load centers are compatible with the THQL2120PGFT?
This breaker is designed exclusively for GE PowerMark Gold Plug-on Neutral Load Centers and ABB ReliaHome Load Centers. It cannot be installed in older panels that lack a plug-on neutral bar.
How does the plug-on neutral connection work on this breaker?
The plug-on neutral design eliminates the need for a traditional pigtail wire. The breaker connects directly to the neutral bar in compatible load centers, saving gutter space and speeding up installation.
What level of ground fault protection does the THQL2120PGFT provide?
It provides Class A, 5mA ground fault protection. This is designed to protect personnel from electrical shock in wet or damp locations like bathrooms, kitchens, and outdoor receptacles. It also includes a built-in self-test feature.
Why might my THQL2120PGFT arrive with ABB branding instead of GE?
ABB acquired GE Industrial Solutions in 2018. Depending on the manufacturing date, this breaker may feature either ABB or GE branding. The product is identical in form, fit, and function regardless of the label.
Can I use the THQL2120PGFT to replace a THQL2120GFT?
You can only use the THQL2120PGFT as a replacement if your existing panel is a plug-on neutral load center. The THQL2120GFT uses a traditional pigtail wire, while the PGFT version requires a direct connection to a plug-on neutral bar.
Does this breaker provide both overcurrent and ground fault protection?
Yes, it features thermal magnetic trip technology for standard overload and short-circuit protection, combined with 5mA ground fault detection in a single unit.
