Cable, Uses Permited
Cable, Uses Permited
(OP)
Article 400.7, NFPA 70, seems to prohibit the use of cable as a primary power feed, 600V, to industrial equipment, unless the installation is temporary. Yet I can buy bus-drop cable, and the manufacturer specifically calls out NFPA 70, Article 368, and states that the cable is suitable for use as branch drop wiring from busways. I cannot find Article 368 in my edition of NFPA 70, 1996. Can anybody help clear up the apparent discrepency?





RE: Cable, Uses Permited
Anyway. . . .
In 2002, Article 368 is Busways. In 1996, Busways was Article 364.
The key paragraphs for you are 400.7(A)(6)[same location & text in 1996 & 2002] and 368.8(B) [which is nearly identical to 364-8(b) in your 1996 edition]. So long as you meet the restrictions in 368.8(B)/364-8(b), you're golden.
