Product FAQs
5 answersWhat load centers are compatible with the Wadsworth A270NI?
This breaker is designed exclusively for Wadsworth Type A load centers. It utilizes a specific plug-on mounting design that is not interchangeable with other manufacturer panels.
Is there a modern replacement for the obsolete Wadsworth A270NI?
Yes. Connecticut Electric manufactures a direct, safety-certified replacement for this breaker under the catalog number UBIA270NI.
What does the NI designation mean on the A270NI breaker?
The NI stands for Non-Interchangeable. This indicates the breaker includes a Class CTL rejection mechanism, which prevents it from being installed in panel slots not designed for it, helping to avoid busbar overloading.
What applications are suitable for this 70A Wadsworth breaker?
This 70-amp, two-pole breaker is typically used for heavy 240V residential loads, such as feeding a subpanel or powering large electric heating equipment. It is HACR rated for use with heating, air conditioning, and refrigeration systems.
What wire sizes are accepted by the terminals on the A270NI?
The box lug terminals on this breaker accommodate wire gauges from 4 AWG up to 1/0 AWG. Ensure the selected wire size meets local electrical codes for a 70-amp circuit.
