Product FAQs
7 answersWhat is the difference between the GE TEY2050B and the TEYD2050B?
The TEYD2050B features a higher short-circuit interrupting rating. While the standard TEY2050B is rated for 14kA at 480/277VAC, the TEYD2050B is rated for 25kA at 480/277VAC, making it suitable for systems with higher available fault currents.
What is the recommended lug torque for the TEYD2050B circuit breaker?
For the factory-installed lugs on the TEYD2050B, the recommended tightening torque is 60 in-lbs for 10 to 4 AWG copper or aluminum wire.
Can the TEYD2050B be reverse fed?
Yes. GE TEYD series circuit breakers do not have line and load markings and are suitable for reverse feed applications.
Which panelboards are compatible with the TEYD2050B?
This breaker is designed for use in GE A-Series lighting panelboards, including Type AS, AD, and AE panels. It requires a bolt-on connection and occupies 1 inch of space per pole.
Does the TEYD2050B provide ground fault or arc fault protection?
No. The TEYD2050B is a standard thermal-magnetic circuit breaker providing long-time and instantaneous (LI) overcurrent and short-circuit protection. It does not include GFCI or AFCI capabilities.
Can I use the TEYD2050B to replace a TEYF2050B?
Yes. The TEYD2050B has a 25kA interrupting rating at 480/277VAC, which exceeds the 18kA rating of the TEYF2050B. It shares the same physical dimensions and bolt-on mounting, making it a safe and compliant upgrade where higher fault current ratings are required.
Is the TEYD2050B rated for HVAC or lighting applications?
Yes. The TEYD2050B is HACR rated for use with heating, air conditioning, and refrigeration equipment. Because it is a 50A breaker, it is also HID rated for high-intensity discharge lighting circuits.
