Nec / Jic?

General question:

Why do I continue to see specifications requiring JIC compliance?

(as in "...this project will meet all NEC / JIC requirements...")

I was under the impression that the JIC is obsolete, superseded in part by the NEC.

Is this just a "throwback" philosophy? I'm open to comments...
 
JIC (Joint Industrial Council) According to records, never was an official standard committee. The documents they porduced go back to 50's. NFPA 79 Electrical Standard for Industrial Machinery covers what they used to.

I would ask the person specifying, if NFPA 79 is required in place of JIC.

JIC was a standard put together by the auto makers and other large industrial companies so that a common standard similar to the NEC would be available for fabricating industrial machinery control panels. Most of the worthwhile stuff was incorporated into NFPA79. NFPA79 is the standard that all industrial machinery control panels (with a few exceptions) must now meet in the US.

JIC was written around the use of relays as logic elements and was never really updated when PLCs came along because there was a move to formalize an official standard for such things.

I would make a point of taking exception to this when you make a bid where the specs require adherence to this spec. Many modern components just cannot be used and meet this spec, mostly because of the wire size requirements.
 
Thanks, all of you, for the quick info.

I am familiar with what the JIC represented - but I didn't understand why
anyone would include/offer it in their bid/quote process. I was wondering if I had missed something obvious or newsworthy, but so far the consensus agrees with me.

Thanks again!
