Does the 2014 NEC limit the length of branch circuit an arc-fault circuit breaker can be applied on?
QO and HOM CAFI breakers
The NEC limits circuit length for AFI outlets; question is if it applies also to breakers.
Per Article 210-12 of the 2014 NEC,A an arc-fault outlet can be a maximum of 50 or 75 feet from the panel for #14 and #12 wire respectively.
An arc fault circuit breaker, however, is suitable for protecting the whole circuit regardless of length.
