Ground wire colored green

[Eddy Current]

I was wondering what the code says about phasing the ground wire. Is there a new code that states the ground wire has to be colored green through out the whole wire now instead of just phasing it green with tape. This may be just an industry thing where i work since we don't have to abide by the NEC code and have our own standards.

Just what industry, location is that?

Many industrial facilities are subject to NEC requirements but management either ignores it or are themselves ignorant of being legally required.

I am just as curious as Smart $. Where and what industry is exempt from NEC other than those listed in 90.2?
I would hate to be a supervisor or higher ranking official of an organization that thought they were exempt, should someone get seriously injured or even worse, killed.

Eastman Chemical Company, im pretty sure we are exempt from the NEC since we generate our own power 90.2(B). Some of the people that wrote the code for the NEC work there too. They have their own set of codes they use instead of the NEC called the Eastman standards.

90.2 doesn't state one is exempt from NEC just because you generate your own power. It states under the exclusive control of an electric utility.

Even then, all the buildings owned by the utility fall under the NEC. Just because we generate our own power doesn't mean we can wire any way we feel at any particular time.

I may be wrong, but I don't see 90.2 as exempting the Eastman Chemical Company.

I could however see the Eastman Standards going well above the NEC minimums.

I agree.

Exceeding the NEC is one thing... conflicting with is another. :happyyes:

What would be an example of something under the exclusive control of an electric company?

The NEC doesn't have jurisdiction over the distribution and transmission lines. RUS borrowers are required to abide by the NESC for those lines. Most IOU's go by the NESC also.

The NEC does have jurisdiction here:

(4) Installations used by the electric utility, such as office
buildings, warehouses, garages, machine shops, and
recreational buildings, that are not an integral part of a
generating plant, substation, or control center.

What this means is that a power company must abide by the NEC adopted by their state and call for inspections on their buildings just like any other commercial building.

Our State Goverment is the same way we must follow the NEC but they can go above. We have things like we can only use steel compression fittings for conduit or we must pull an EGC in conduit. The conduit cannot be used as an EGC.

There are NEC rules for when a black wire can be reidentifed with green tape.
Before the 2005 NEC green was used to identify the EGC but was not restricted to the EGC.
Starting with the 2005 NEC green is restricted to the EGC only.

Substation
Metering equipment
Hydro electric

In many cases the last two items are not owned or under the control of an electric utility.
