Use this cord when you have a power demand that exceeds 18 or 16 gauge cords. Note: This cord will NOT fit into the opening of our 1/8ip sockets. 14 gauge cord would not typically go directly into a socket, for example you may have a 14 gauge lead coming down from the ceiling (if you are powering a LOT of bulbs, and 18 or 16 gauge cord won't handle), and that would typically branch off into separate cords going to each socket (usually 18 gauge).
