Product FAQs
6 answersWhat is the direct replacement for the obsolete Cutler-Hammer QCGF2030?
The Eaton QCGFT2030 is the direct drop-in replacement for the legacy QCGF2030. It maintains the same physical footprint and feed-thru mounting style while adding an automatic self-test feature to comply with current UL 943 standards.
How is the QCGFT2030 installed in an electrical system?
This is a feed-thru, cable-in/cable-out breaker. Instead of snapping onto a panel busbar, it uses box lugs on both the line and load sides for direct wire connections. It is typically unit-mounted in Eaton Quicklag enclosures or custom OEM control panels.
What level of ground fault protection does this breaker offer?
The QCGFT2030 provides Class A personnel protection. It is calibrated to trip when it detects a ground fault leakage current of 5mA, protecting users from severe electrical shock in wet or outdoor locations like spas and HVAC units.
Are the terminal lugs rated for aluminum conductors?
Yes, the line and load box lugs are dual-rated for both copper and aluminum (Cu/Al) wiring. The terminals accept conductor sizes from 14 AWG to 4 AWG.
Is this breaker suitable for heating and cooling equipment?
Yes, the QCGFT2030 is HACR rated. It can be safely used for branch circuit protection on heating, air conditioning, and refrigeration equipment that requires a 30A ground fault breaker.
How does the self-test function operate on the QCGFT2030?
The breaker automatically conducts periodic internal tests to confirm the ground fault detection circuitry is fully operational. If the self-test detects a failure in the GFCI mechanism, the breaker will trip and deny power to the circuit until replaced.
