Product FAQs
6 answersWhat level of ground fault protection does the B220GFHH provide?
This breaker provides Class A 5mA ground fault protection. It is designed for personnel safety, de-energizing the circuit when a ground fault is detected.
What does the "HH" suffix in the B220GFHH catalog number indicate?
The "HH" designates an extra-high interrupting rating of 65kAIC at 120/240V. This is significantly higher than the standard 10kAIC (B220GF) or 22kAIC (B220GFH) versions of this breaker.
Which Siemens panelboards are compatible with the B220GFHH?
This HBL-frame bolt-on breaker is designed for use in Siemens P1, P2, P3, P4, and P5 commercial panelboards.
Can the B220GFHH be installed in a standard residential load center?
No, this is a bolt-on breaker designed specifically for commercial Siemens panelboards (P1 through P5). It will not fit in standard plug-on residential load centers.
How is the neutral connection handled during installation of the B220GFHH?
This breaker is equipped with a pigtail neutral wire. During installation, the pigtail must be routed and connected directly to the panelboard's neutral bar for the ground fault circuitry to function correctly.
Does the B220GFHH provide arc fault (AFCI) protection?
No, this model is a dedicated Ground Fault Circuit Interrupter (GFCI) for personnel protection. It does not include combination AFCI protection.
