How it works

AFCI circuit plan and breaker inventory

Count actual planned AFCI or dual-function breaker assemblies from a reviewed circuit schedule. Requirements remain circuit-specific and edition-specific. An independently approved alternative protection method can be recorded without pretending it requires another AFCI breaker.

Breaker quantity = count of distinct physical breaker IDs with consistent AFCI or dual-function type; unresolved circuit decisions remain in the result.
