Product FAQs
6 answersWhich panelboards are compatible with the QCGF1020 breaker?
This unit mount breaker is designed specifically for Eaton Quicklag panelboards and DIN rail enclosures that accommodate cable-in, cable-out configurations.
What level of ground fault protection does the QCGF1020 provide?
This breaker is a Class A GFCI with a 5mA trip sensitivity threshold, designed specifically for personnel safety against electric shock.
Does this breaker provide equipment protection or personnel protection?
The QCGF1020 provides personnel protection via its 5mA ground fault trip threshold. Applications requiring equipment protection typically need a 30mA device from the QCGFEP series, such as the QCGFEP1020.
How is the line side connected on this breaker?
Unlike plug-on or bolt-on breakers, the QCGF1020 uses a feed-thru connection. This requires landing wires into box lugs on both the line and load sides rather than mounting directly to a panel busbar.
Does the QCGF1020 require a neutral connection to operate?
Yes, you must connect the included pigtail neutral wire to the panel neutral bar to power the internal ground fault sensing circuitry properly.
Are there alternative breakers with a higher interrupting rating?
Yes, if your panel requires a higher fault current rating than the 10kAIC provided by this model, Eaton offers the QCHGF1020 which carries a 22kAIC rating at 120V.
