[Cody AV]

Question: What article of the NEC 2008 does a Chrome Plating Shop have to follow?


options are: 1= Art 669 Electro Plating, 2= Art 668 Electrolytic Cells, 3= Art 516 Spray, Dripping/Coating, 4= None

I would say no on 668

ARTICLE 668

Electrolytic Cells

668.1 Scope. The provisions of this article apply to the installation
of the electrical components and accessory equipment
of electrolytic cells, electrolytic cell lines, and process
power supply for the production of aluminum, cadmium, chlorine,
copper, fluorine, hydrogen peroxide, magnesium, sodium,
sodium chlorate, and zinc.

Not covered by this article are cells used as a source of
electric energy and for electroplating processes and cells
used for the production of hydrogen.

This does not sound like chrome plating to me.

ARTICLE 516
Spray Application, Dipping,
and Coating Processes

516.1 Scope. This article covers the regular or frequent application
of flammable liquids, combustible liquids, and combustible
powders by spray operations and the application of
flammable liquids, or combustible liquids at temperatures
above their flashpoint, by dipping, coating, or other means.

It sure seems like this applies

ARTICLE 669
Electroplating
669.1 Scope. The provisions of this article apply to the
installation of the electrical components and accessory
equipment that supply the power and controls for electroplating,
anodizing, electropolishing, and electrostripping.
For purposes of this article, the term electroplating shall be
used to identify any or all of these processes.

I agree... Article 669.

I'm with iwire and Smart $ on this. Chrome plating is just electroplating with chromium instead of silver, gold, or some other metal.
