Code Question of the Daytextbook

    CQD: 10/2/2014

    Question: Does the additional circuit and receptacle outlet requirements for garages from the 2014 NEC disallow the use of a receptacle outlet circuit being used in the garage for receptacle outlets and feeding various receptacle outlets outside the garage if there is an additional receptacle outlet circuit feeding the required garage receptacle outlets that does not leave the garage. Another words; if there are two garage receptacle outlet circuits, do both have to meet the requirement that disallow the use of a receptacle outlet circuit being used in the garage if all other code provisions are met?
