Description

Sourced for residential applications, the Wadsworth A230NI provides reliable thermal-magnetic protection for 30-amp circuits.

Product FAQs

6 answers
Which 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.

    Breaker panel

    I recently purchased a breaker panel cover. It arrived in a timely manner well packed and unharmed.

    The shipping was free so I was sceptical.

    All is well.
