Product FAQs
6 answersWhich panelboards are compatible with the GHQ2020 circuit breaker?

Yes, Eaton G-frame circuit breakers, including the GHQ series, are suitable for reverse feed use.
Does the GHQ2020 require a separate mounting kit?
No, the GHQ2020 features a bolt-on connection that mounts directly to the bus in compatible Pow-R-Line and Westinghouse panelboards without requiring a separate hardware kit.
