Product FAQs
4 answersWhat load centers accept the NA2P110 circuit breaker?
This breaker is designed specifically for Federal Pacific Stab-Lok load centers. Because it is an NA series thick breaker, it requires two inches of total panel space, which is one inch per pole.
What is the modern cross-reference for the Federal Pacific NA2P110?
Connecticut Electric manufactures a direct aftermarket replacement for this breaker. You can cross-reference it using catalog number UBIF2110N.
Are Federal Pacific Stab-Lok panels safe to continue using?
Original FPE Stab-Lok panels and breakers have a documented history of safety issues, including a high rate of failure to trip during overcurrent conditions and loose busbar connections. Most licensed electricians and home inspectors strongly recommend upgrading the entire panel to a modern, code-compliant system rather than replacing individual breakers.
What wire gauge is required for the NA2P110 breaker lugs?
The terminal lugs on this 110-amp breaker are designed to accept wire sizes ranging from 4 AWG up to 2/0 AWG. Always verify the exact wire size required for your specific application and conductor material based on the National Electrical Code.
