Product FAQs
5 answersWhat wire sizes and materials are compatible with the standard lugs on the GD3020?
The factory-installed pressure lugs accept 14 AWG through 1/0 AWG copper (Cu) or aluminum (Al) conductors.
Can I use the GD3020 to replace a GHC3020 or GHB3020 circuit breaker?
Yes. The GD frame shares the same physical dimensions as the GHC and GHB frames and can be interchanged. Additionally, the GD3020 features a straight 480VAC rating, making it suitable for 3-phase delta systems where GHC and GHB breakers (which are typically limited to 480Y/277V) cannot be used.
How does the GD3020 mount inside a panelboard or enclosure?
This is a unit-mount, feed-thru circuit breaker. It bolts directly to the backpan of the enclosure or panelboard rather than plugging onto a busbar, and it requires wired connections on both the line and load terminals.
How is this 3-pole breaker applied in 250VDC systems?
While the GD3020 is rated for 125/250VDC at 10kAIC, applying it at the full 250VDC rating requires wiring two of the three poles in series.
Is the GD3020 HACR rated for HVAC equipment?
Yes, Eaton Series C G-frame molded case circuit breakers carry a HACR rating, making them suitable for branch circuit protection of heating, air conditioning, and refrigeration equipment.
