Product FAQs
8 answersHow should I evaluate the 10kAIC interrupting rating?
The interrupting rating is 10kAIC at 120V. For that voltage, the available fault current at the installation point must not exceed the interrupting rating.
What does the GFCI protection do?
GFCI protection detects an imbalance between outgoing and returning current and trips to reduce electric shock risk. Choose this feature when the circuit requires ground-fault protection for personnel.
What does the pigtail neutral connection require during installation?
Plan to route and terminate the neutral pigtail as part of the GFCI installation. Treat the pigtail as a neutral connection, not an equipment grounding conductor.
What protection does the LI trip function offer?
LI combines long-time and instantaneous tripping. Long-time protection responds to sustained overcurrent, while instantaneous protection responds to high-magnitude overcurrent without an intentional delay.
What conductor sizes can the BRN320GF terminals accept?
The conductor range is AWG 14 to AWG 4. Select a conductor within that range while also meeting the circuit's ampacity and installation requirements.
What dimensions should I use when planning installation space?
The breaker body is 3 in high, 3 in wide and 4.25 in deep. Account for these dimensions along with the space needed for conductor routing and termination.
What system voltage is the Eaton BRN320GF rated for?
The Eaton BRN320GF is rated 208Y/120V. The Y indicates a wye system, so review both the system voltage and its configuration when selecting the breaker.
What phase and pole configuration should I account for during installation?
The Eaton BRN320GF is a 3-phase, 3-pole miniature circuit breaker. Account for all 3 poles when planning phase-conductor connections.
