Product FAQs
7 answersWhat electrical panels are compatible with the Wadsworth A250NI?
This breaker is designed exclusively for use in Wadsworth Type A load centers. It will not fit in panels made by other manufacturers.
Are there modern replacements available for the Wadsworth A250NI?
Yes. Because Wadsworth is an obsolete brand, Connecticut Electric manufactures a safety-agency-listed replacement under the catalog number UBIA250NI, which is approved for use in Wadsworth Type A panels.
How is the A250NI installed into a Wadsworth load center?
The breaker features a plug-on design that snaps directly onto the panel busbar. Ensure the panel is de-energized before seating the breaker firmly into the Type A mounting clips.
What wire sizes are accepted by the box lugs on the A250NI?
The terminal box lugs accept wiring ranging from 14 AWG to 4 AWG. Ensure the selected wire gauge safely supports the 50-amp circuit requirement according to local electrical codes.
What types of loads is a 50-amp, 2-pole breaker typically used for?
A 50A, 240V circuit is commonly used for heavy-draw residential appliances such as electric ranges, large hot water heaters, or central air conditioning systems. Always verify your equipment's specific electrical requirements.
What does the "NI" in the A250NI catalog number signify?
The "NI" stands for Non-Interchangeable. This refers to the trip mechanism design, which prevents the breaker's trip setting from being altered after manufacturing.
Why is it important to use a Type A breaker in a Wadsworth panel?
Using the correct Type A breaker ensures a secure connection to the busbar. Installing incompatible breakers can lead to loose connections, arcing, and severe fire hazards.

The shipping was free so I was sceptical.
All is well.
