For the same reason, fan controller output wires should not share a conduit withanother fan controllers output leads, or other power circuits (lighting, motors, etc.).varieties must be avoided. Do not use solid core cable of any size or insulation class for motor wiring. Use of such typesof cabling may result in nuisance tripping or premature equipment failure.For many installations, unshielded cable is adequateif it can be separated from sensitive circuits.
