GFCI convenience outlets on automated machinery

[bbrummon]

Hi All,

Dose the law require convenience outlets, used to plug in your lap top for programming, to be on GFCI protected outlets on automatic equipment used in factories?

From NFPA 79 (2015) 15.1.1 (1) says yes but is NFPA79 Law?

OSHA 1926.404(b)(1) requires temporary 120V wiring to be protected but would the burden of this fall on the facility were the machine resides or on the machine builder who provided the outlet. Facility could always use a GFCI protected cord.

NEC 70 (2014) focuses on residential wiring but the spirit of the law would seem to say that if you can touch something that is grounded (Sink) the outlets nearby should be GFCI protected. Automated machines and there electrical cabinets are usually grounded.

Thanks,

Bob

Are you asking that the receptacles this equipment is plugged into is supposed to gfci protected? In industrial/factory settings?

Try to be a little more specific.

There are sections in the NEC that deal with non residential settings and 210.8(B) tells you gfci locations outside of dwellings.
590 (A)(2) could also be applicable- if the equipment gets moved often- could be considered temporary.

I work at designing Industrial Machinery (NFPA 70 Article 670). Things like CNC mills ect. So this is a factory setting. Lots of this machinery have 120V receptacles for users to plug a laptop pc into for programing. Sometimes maintenance may use these for hand held power tools. I believe best practice would be to have this be GFCI but is that the code law? That is unclear to me.

Other than the above mentioned stuff in 590 or 210.8, I haven't fund anything that says gfci is required with the circumstances described- maybe somebody like don_resqcapt19 will chime in.

If the city or state has adopted NFPA 70 (aka "the NEC"), and most have (some with local amendments), then it is the law. Only exceptions I can think of off-hand are Chicago and NYC which have their own codes.

It is not required in general. There might be a few cases where it is, such as where the equipment is located outdoors.

It is fairly common practice though.
