Wiring methods. The arrangements of this paragraph usually do not apply to conductors which form a fundamental element of equipment such engines, controllers, motor controls centers and like equipment.
Material raceways, cable armour, along with other material enclosures for conductors will probably be metallically joined up with along into a continuous electric conductor and will probably be therefore connected with all containers, fixtures, and cabinets as to supply effective electric continuity.
Wiring in ducts. No wires programs of every sort will be put in in ducts accustomed transport dirt, loose inventory or flammable vapors. No wiring system of every kind shall be setup in virtually any duct employed for vapor elimination or even in any shaft containing just these ducts.
Extent. The provisions of part (a)(2) for this point apply to short-term electrical power and light wiring techniques which may be of a category lower than could well be needed for a long-term installations. Except as particularly changed in section (a)(2) of this part, other specifications within this subpart for permanent wiring shall apply at temporary wires installments. Temporary wires shall be eliminated right away upon conclusion of building or perhaps the function for which the wiring was setup.
General requirements for short-term wires –
Feeders shall originate in a distribution heart. The conductors will be run as multiconductor wire or wire assemblies or within raceways; or, where maybe not susceptible to physical harm, they could be manage as open conductors on insulators not more than 10 feet (3.05 m) separate.
