Product FAQs

6 answers
What panelboards are compatible with the GHB1020HID circuit breaker?

This G-frame breaker is designed for installation in Eaton Pow-R-Line C panelboards, switchboards, and motor control centers. It is also backward compatible with legacy Cutler-Hammer and Westinghouse Pow-R-Line C equipment.

What does the HID designation mean on the GHB1020HID?

The HID suffix indicates the breaker is rated for High Intensity Discharge lighting loads. It is engineered to safely manage the demanding inrush currents generated by commercial and industrial HID lighting fixtures without nuisance tripping.

What wire gauge is accepted by the terminals on the GHB1020HID?

The standard factory lugs on this 20A breaker accept copper or aluminum conductors ranging from 14 AWG to 10 AWG.

Can the GHB1020HID be utilized in DC circuits?

Yes, in addition to its standard AC ratings, this breaker is rated for 125VDC applications and provides a 14kAIC interrupting capacity at that voltage.

How is the GHB1020HID secured to the panelboard?

It utilizes a bolt-on mounting configuration. This ensures a rigid, secure mechanical and electrical connection to the busbar, which is ideal for continuous heavy-duty operations and environments subject to vibration.

Are the trip settings adjustable on the GHB1020HID?

No, this breaker features a thermal-magnetic trip unit with fixed long-time and fixed instantaneous (LI) trip functions. The trip settings cannot be adjusted in the field.

    Used model

    Breaker ohm tested out fine and currently working on load test with a longer term battery charger. So far so good. Packaged very well no visible damages during shipping. Even received a follow up call from customer that I missed.

    Good Product, but Disappointed With the Service

    Good product, but I was disappointed with the service. I accidentally placed two separate orders and ended up paying freight on both. I had requested that they combine the orders, and had that been done with the freight waived, it would have saved me money.

    Other than that, everything was good. I’m just disappointed that no one communicated this to me.
