Product FAQs

5 answers
What panels accept the Wadsworth B1530NI tandem breaker?

This tandem breaker is designed exclusively for legacy Wadsworth load centers that accept Class CTL non-interchangeable breakers. It will not fit panels from other manufacturers.

Is there a modern replacement for the Wadsworth B1530NI?

Yes, the UBIA1530NI is the direct aftermarket replacement for this legacy Wadsworth tandem breaker.

Can I install this tandem breaker in any slot within my Wadsworth panel?

No. Because it is a Class CTL breaker, it must be installed in panel slots specifically notched to accept tandem breakers. This prevents overloading the physical capacity of the panel.

What does the A-NI frame designation mean for this breaker?

The A-NI frame indicates that this is a non-interchangeable breaker. The thermal magnetic trip unit is fixed and cannot be swapped out or adjusted in the field.

How does a tandem breaker like the B1530NI function?

A tandem breaker provides two independent circuits in the physical space of a single-pole breaker. For the B1530NI, this includes one 15-amp circuit and one 30-amp circuit within a single panel slot.
