Product FAQs
7 answersWhat panels and enclosures is the Eaton QCGF2050 compatible with?
This breaker is specifically designed for use in Eaton Quicklag panelboards and standard DIN rail enclosures. It is not compatible with standard residential BR or CH load centers.
How is the QCGF2050 circuit breaker mounted?
It features a unit mount, feed-thru design. This cable-in, cable-out configuration allows it to be installed directly into Quicklag panelboards or mounted onto a standard DIN rail.
How do I wire the neutral connection for this GFCI breaker?
This breaker is equipped with a pigtail neutral. The coiled white pigtail wire must be connected directly to the neutral bus bar in your panelboard for the ground fault sensing circuitry to function properly.
What level of ground fault protection does the QCGF2050 provide?
As a Class A Ground Fault Circuit Interrupter (GFCI), this breaker is designed for personnel safety and will trip if it detects a ground fault leakage current of 5mA.
What does the LIG trip function code mean on this breaker?
The LIG designation indicates that the thermal-magnetic trip unit provides Long-Time overload protection, Instantaneous short-circuit protection, and Ground Fault detection in a single device.
What wire gauge is required for the box lug terminals?
The line and load terminals on this breaker are designed to accept copper or aluminum wire sizes ranging from 14 AWG to 4 AWG.
Can I use the QCGF2050 to replace a QCGFEP2050?
No. While they share the same physical frame and 50A rating, the QCGF is a Class A GFCI with a 5mA trip threshold for personnel protection. The QCGFEP is an Equipment Protection Device with a 30mA trip threshold, designed to protect machinery rather than people.
