Product FAQs
8 answersWhat load centers are compatible with the UBITBA230 circuit breaker?
This UL Classified breaker is approved for installation in Challenger Type A, Crouse-Hinds Type MH, Murray Type MP, and Thomas & Betts Type A load centers.
Which legacy circuit breakers can the TBA230 replace?
The TBA230 is a direct UL Classified replacement for legacy A230, MH230, and MP230 circuit breakers originally manufactured by Challenger, Crouse-Hinds, and Murray.
What wire sizes are accepted by the terminals on this breaker?
The box lug terminals are designed to accept wire gauges from 14 AWG up to 4 AWG. Always ensure your wire size is appropriately rated for a 30A circuit according to the National Electrical Code.
What types of electrical loads is a 30A 2-pole breaker typically used for?
A 30A, 240V circuit is commonly used for residential appliances such as electric water heaters, clothes dryers, and smaller central air conditioning units. You must verify the specific appliance load requirements before installation.
Is it safe to install this Eaton Classified breaker in a non-Eaton panel?
Yes. As a UL Classified breaker, it has been rigorously tested by Underwriters Laboratories to be mechanically and electrically interchangeable with specific competitor panels. This ensures safe operation and maintains compliance with the National Electrical Code.
How does this breaker connect to the panel busbar?
It utilizes a plug-in mounting style, allowing it to snap directly onto the busbar of compatible load centers without requiring bolt-on hardware. Ensure the panel is completely de-energized before seating the breaker.
What does the LI trip function indicate on this thermal-magnetic breaker?
The LI designation means the breaker provides Long-Time overload protection through its thermal element and Instantaneous short-circuit protection through its magnetic element. This is the standard protection profile for residential branch circuits.
Can I use this 2-pole breaker for a standard 120V single-pole circuit?
No. This is a 2-pole breaker designed to provide 240V or 120/240V split-phase power. It should not be used to supply a standard 120V single-pole branch circuit.
