Product FAQs
8 answersWhat panelboards are compatible with the B220EGHH?
This bolt-on breaker is designed exclusively for installation in Siemens P1, P2, P3, P4, and P5 commercial panelboards.
Can I install this breaker in a standard residential load center?
No. The B220EGHH utilizes a bolt-on connection designed specifically for commercial P-series panelboards. It is not compatible with standard plug-on residential load centers.
What is the ground fault trip threshold for this breaker?
The B220EGHH features a 30mA ground fault trip threshold. This classifies it as Ground Fault Equipment Protection (GFEP), which is intended to protect sensitive machinery from line-to-ground faults.
What is the difference between GFEP and GFCI protection?
GFEP breakers have a 30mA trip threshold designed to protect equipment from damage. In contrast, Class A GFCI breakers have a highly sensitive 5mA trip threshold designed specifically for personnel protection against electric shock.
What does the HH suffix in the B220EGHH catalog number signify?
The HH suffix indicates an extra-high interrupting rating of 65kAIC. Standard EG models are rated at 10kAIC, while EGH models are rated at 22kAIC.
Does the B220EGHH require a neutral connection for a straight 240V load?
Yes. Even if the connected 240V load does not utilize a neutral wire, the white pigtail wire on the breaker must be connected to the panel neutral bus. This powers the internal ground fault sensing circuitry.
How does the breaker detect a ground fault condition?
The breaker uses residual differential current monitoring. It continuously compares the current leaving the breaker to the current returning. If the imbalance exceeds the 30mA threshold, the breaker trips to de-energize the circuit.
Is this breaker suitable for HVAC equipment protection?
Yes, this thermal magnetic breaker carries a HACR rating, making it fully approved for use with heating, air conditioning, and refrigeration systems that require equipment-level ground fault protection.

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.
