Dennis Alwon Moderator Staff member Location Chapel Hill, NC Occupation Retired Electrical Contractor Dec 7, 2010 #2 Do you mean will it allow the ocpd to be larger then the wire ampacity? You can always have less amps on the conductor if the OCPD is correct so I think you meant what I stated above.
