Product FAQs
6 answersWhich electrical panels accept the Wadsworth A230NI circuit breaker?
This breaker is designed exclusively for legacy Wadsworth Type A load centers. It features a non-interchangeable (NI) metal foot and Class CTL rejection mechanism to ensure proper fitment in compatible Wadsworth panels.
Is there a modern replacement available for the obsolete Wadsworth A230NI?
Yes. Connecticut Electric manufactures a direct, safety-certified replacement under the catalog number UBIA230NI. This modern substitute is ETL listed to UL 489 standards and fits the same Wadsworth Type A panels.
What size wire is required for installing the A230NI breaker?
The box lug terminals on this breaker accept copper or aluminum wiring ranging from 14 AWG to 6 AWG. Always verify the exact wire gauge required for your specific 30-amp circuit based on local electrical codes.
What types of loads is a 30-amp, 2-pole breaker typically used for?
A 30-amp, 240-volt breaker is commonly used to protect dedicated circuits for medium-draw residential appliances, such as electric water heaters, clothes dryers, or small central air conditioning units.
Does the A230NI provide both overload and short-circuit protection?
Yes. It utilizes fixed thermal-magnetic trip technology. The thermal element provides long-time protection against gradual overloads, while the magnetic element offers instantaneous tripping to safely clear short circuits.
Can I install this Wadsworth breaker in a modern panel from a different brand?
No. The A230NI has a proprietary plug-on design with a specific metal foot configuration. It will not fit or operate safely in panels made by Square D, Siemens, Eaton, or other modern manufacturers.

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