Product FAQs
6 answersWhat panelboards are compatible with the GE TEY350 circuit breaker?
The TEY350 is designed for use in GE A-Series lighting panelboards, specifically Type AD, AE, and AQ models. It utilizes a bolt-on mounting style to ensure a secure connection within these commercial distribution systems.
What is the recommended terminal lug torque for the TEY350 breaker?
Lug tightening torque depends on the installed wire size. Torque the terminals to 35 in-lb for 10 AWG wire, 40 in-lb for 8 AWG wire, and 45 in-lb for 6 AWG to 4 AWG conductors.
Are there direct replacements with higher interrupting ratings if my system requires more than 14kAIC at 480Y/277VAC?
Yes. The GE TEY frame offers multiple tiers for higher short-circuit ratings. You can upgrade to the TEYF350 for 18kAIC, TEYD350 for 25kAIC, TEYH350 for 35kAIC, or TEYL350 for 65kAIC at 480Y/277VAC while maintaining the same physical panel footprint.
Can the GE TEY350 breaker be reverse-fed or back-fed?
Yes, the TEY350 is suitable for reverse-feed applications. Since the breaker does not have strict Line and Load marking restrictions, it can be back-fed when installed in accordance with standard electrical code guidelines.
Can the TEY350 be utilized in direct current systems?
Yes, this thermal magnetic breaker is rated for up to 250VDC with a 10kA interrupting capacity, allowing it to be safely applied in standard direct current control and distribution circuits.
What type of conductors can be landed on the TEY350 lugs?
The terminal lugs accept both copper (Cu) and aluminum (Al) wire, accommodating solid or stranded conductors from 10 AWG up to 4 AWG.
