What Is The Proper Method For Securing AC and MC Cables?

NEC Articles 320.30 and 330.30 denotes the different requirements for securing Armored and Metal Clad cables. Although similar in appearance, each cable has unique requirements. Armored cable [NEC Article 320.30(C)] must be secured at intervals not exceeding 4-1/2 feet and within 12″ of box or fitting. Metal Clad cable [NEC Article 330.30(B)] must be secured at least every 6 feet. Cables with four or fewer conductors “sized 10 AWG or less” must be secured within 12″ of box or fitting.

Why Use Steel Safety Plates?

NEC Article 300.4(F) specifies that cable or raceway-type wiring may be installed in wooden stud grooves, to be covered by wallboard or similar covering, if protected by 1/16″ thick steel plate. The steel plate must have the same width as the stud, and must be securely fastened to the stud.

Why Can’t Plastic Insulating Bushings Be Used To Connect A Conduit To An Enclosure?

Plastic insulating bushings must be used in conjunction with two locknuts when connecting threaded rigid or IMC conduit, containing No. 4 or larger un-grounded conductors, to boxes or enclosures. Bushings composed entirely of plastic cannot be used to secure conduit to the enclosure. A locknut is required on the inside and outside of the enclosure in addition to the plastic insulating bushing. Temperature rating of the plastic insulating bushing must not be less than the insulation rating of the conductors.
