horizontal cable

A type of inside cable designed for horizontal use in non-plenum areas. While hori-

zontal cable must be fire retardant, the National Electrical Code (NEC) specifications are not as demanding as those governing the use of plenum cable or riser cable. See also NEC, plenum, plenum cable, and riser cable.
