When to consider an AFCI - The 1999 edition of the National Electrical Code, the model code for electrical wiring
adopted by many local jurisdictions, requires AFCIs for receptacle outlets in bedrooms,
effective January 1, 2002. Although the requirement is limited to only certain circuits in
new residential construction, AFCIs should be considered for added protection in other
circuits and for existing homes as well. Older homes with aging and deteriorating wiring
systems can especially benefit from the added protection of AFCIs. AFCIs should also
be considered whenever adding or upgrading a panel box while using existing branch
circuit conductors.
