Product FAQs
5 answersWhat panels are compatible with the Wadsworth A30NI circuit breaker?
The A30NI is designed exclusively for use in Wadsworth Type A load centers. It features a proprietary plug-on mounting clip that is not interchangeable with other breaker brands.
Is there a modern replacement for the obsolete Wadsworth A30NI?
Yes. Connecticut Electric manufactures a direct, ETL-listed replacement under catalog number UBIA30NI. This replacement is specifically approved for use in Wadsworth Type A panels.
What wire sizes are accepted by the A30NI box lugs?
The box lugs on the A30NI accept wire gauges ranging from 14 AWG to 6 AWG. Ensure the selected wire size is appropriate for a 30A circuit according to current NEC guidelines.
What does the NI in the A30NI catalog number indicate?
The NI stands for Non-Interchangeable. This designates a Class CTL (Circuit Total Limiting) configuration, which prevents installing more breakers than the panelboard is rated to hold.
Can I use a standard 1-inch breaker from another brand in a Wadsworth Type A panel?
No. Wadsworth Type A load centers require breakers with a specific mounting clip design. Standard 1-inch breakers from other manufacturers will not seat properly and pose a severe safety and fire risk.

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.
