Product FAQs
5 answersWhich vintage panels will accept the QBH1020EP breaker?
This bolt-on breaker is engineered to fit classic Commander B/BC, CEB, and Sylvania bolt-on load centers, providing a modern replacement for aging electrical systems.
What is the ground fault trip sensitivity for the QBH1020EP?
This breaker features a 30mA ground fault trip level. It is specifically calibrated for Ground Fault Equipment Protection (GFEP) to safeguard machinery, heat trace cables, and HVAC equipment from damaging line-to-ground faults.
Is the QBH1020EP suitable for protecting bathroom or kitchen receptacles?
No. This is a GFEP breaker with a 30mA trip threshold designed for equipment protection. It does not meet the 5mA Class A GFCI requirements mandated by the NEC for personnel protection in wet locations.
How do I install the pigtail neutral on this breaker?
The attached pigtail wire must be routed and secured directly to the neutral bus bar in your load center. This connection is required to power the internal circuitry that monitors for ground faults.
Can I use this Eaton breaker to replace an original Commander QBH breaker?
Yes. Eaton owns the rights to the original Commander and Sylvania designs and manufactures the QBH series as a direct, certified replacement for those legacy bolt-on breakers.
