Product FAQs
5 answersWhat panelboards are compatible with the GE TEF124015 circuit breaker?
This bolt-on E-Frame molded case circuit breaker is designed to mount in compatible GE A-Series panelboards, switchboards, and motor control centers.
Has the GE TEF124015 been replaced by a newer model?
Yes, the legacy TEF series has been officially replaced by the GE TED series. The direct cross-reference for this unit is the TED124015, which shares the same physical dimensions, pole count, and electrical ratings.
What wire sizes are accepted by the standard lugs on this 15A breaker?
When equipped with standard factory lugs, the TEF124015 typically accepts 14 AWG to 8 AWG copper or aluminum wire. Always verify the specific lug stampings on your unit before terminating conductors.
How does the thermal magnetic trip unit function on the TEF124015?
The non-interchangeable trip unit provides two levels of protection. The thermal component responds to prolonged overloads, while the magnetic component provides instantaneous tripping during severe short-circuit faults.
What is the minimum copper wire size required for this 15A circuit breaker?
According to standard electrical codes, a 15A breaker requires a minimum of 14 AWG copper wire. Using undersized wire can lead to overheating and fire hazards before the breaker has a chance to trip.
