Product FAQs
5 answersWhat panelboards are compatible with the Siemens B220GF?
The B220GF is a bolt-on circuit breaker designed specifically for installation in commercial Siemens P1, P2, P3, P4, and P5 panelboards. Because of its bolt-on mounting style, it cannot be used in standard residential plug-on load centers.
How is the neutral connection handled on the B220GF?
This breaker utilizes a pigtail neutral connection. During installation, the attached factory white pigtail wire must be securely routed and connected to the panelboard's neutral bus bar to ensure the internal ground-fault detection circuitry receives reference power.
What level of ground-fault protection does the B220GF provide?
The B220GF provides Class A ground-fault protection. It is engineered to trip when it detects a ground-fault current of 5mA, ensuring personnel safety in wet or damp environments as required by the NEC.
Can the B220GF replace older Siemens BF220 or BLF220 breakers?
Yes. The B220GF is part of the modern Siemens BLFB family and serves as a direct replacement for legacy Type BLF and BF 20-amp, 2-pole bolt-on GFCI breakers, including catalog numbers BF220 and BLF220.
Is the Siemens B220GF designed for equipment protection or personnel protection?
As a Class A GFCI device with a 5mA trip threshold, the B220GF is designed strictly for personnel safety against electric shock. This differs from Ground Fault Equipment Protection (GFEP) breakers, which typically feature a higher 30mA trip threshold and are not classified as Class A.

I ordered breakers from this company. They were fast and prompt on the initial order. I ended up returning part of the order as I did not need those breakers. To say the very least I am not satisfied with the return process. They do not respond to emails and will not return a phone call. I'm still waiting on the partial refund for these items as their restocking fee is ridiculously high. Please make sure you are buying what you need from this company as the return process is painful ,frustrating and costly.
