Product FAQs
7 answersWhat is the ground fault trip sensitivity for the B320EGHH?
This GFEP (Ground Fault Equipment Protection) breaker has a 30mA trip threshold. It is designed to protect commercial machinery and heat trace cables from line-to-ground faults, rather than providing 5mA personnel protection.
Which panelboards accept the B320EGHH breaker?
This bolt-on breaker is specifically designed for installation in Siemens P1, P2, and P3 commercial panelboards.
How is the neutral connection wired on this GFEP breaker?
The B320EGHH features a pigtail neutral wire. This pigtail must be connected directly to the panelboard neutral bar to power the internal ground fault circuitry and ensure accurate fault detection.
What wire sizes and materials are supported by the load lugs?
The load terminals accept 14 to 6 AWG copper conductors or 12 to 6 AWG aluminum conductors.
What does the HH suffix indicate in the B320EGHH catalog number?
In the Siemens BQ breaker family, the HH suffix designates the HBQ frame. This indicates an extra-high interrupting capacity of 65kAIC at 240V, compared to standard 10kAIC BQ frames.
Can the B320EGHH be used to meet NEC requirements for personnel GFCI protection?
No. This is a 30mA Ground Fault Equipment Protection (GFEP) device. It does not meet the 5mA Class A GFCI requirements for personnel shock protection in areas like bathrooms or kitchens.
Are the thermal and magnetic trip settings adjustable on this breaker?
No, the B320EGHH utilizes fixed thermal and fixed magnetic trip settings alongside its 30mA ground fault protection.
