Temp. Power for Construction Site, 590

[Jake R. Laws]

In 590.6(B)(2)Assured Equip. Grounding Conductor Program it says in part: grounding conductor for all cord sets, receptacles that are not part of the permanent wiring of the building or structure, etc. The site electricians build a temporary distribution (bang board) with a 15 or 25kva transformer with breakers than either emt or flex (sealtite) to outlets, all mounted on a unistrut stand, all equipment rated 3R. The outlets are 120, 240 some 208 depending on the need and some 480 outlets. All supplied using chapter 3 methods, emt, flex, rigid, etc. and mounted on unistrut rack. Rack is grounded per 250.32(B)(1) (2005 code) Supply power to the rack is rubber cord (Type W), under 590. These units stay in place for up to a year or less. They are for temp power. All cord sets are under the AEGCP. The question is concerning the outlets mounted on the rack whether they also should be included in the AEGCP.

Jake, I thought the AEGCP was for cords ?

The receptacle outlets that do not have GFCI protection must be part of the AEGCP.

(2) Assured Equipment Grounding Conductor Program. A written assured equipment grounding conductor program continuously enforced at the site by one or more designated persons to ensure that equipment grounding conductors for all cord sets, receptacles that are not a part of the permanent wiring of the building or structure, and equipment connected by cord and plug are installed and maintained in accordance with the applicable requirements of 250.114, 250.138, 406.3(C), and 590.4(D).

The outlets on the power rack are permanent for the structure. But I quess you are saying since it is not a building the outlets should be tested? Do you also include the outlets on a generator used for temporary power?

Jake,
If the receptacles in question are going to become part of the building or structure's electrical system when the construction is finished they are not subject to the AEGCP. If they are only there for the construction project, they are. I am not sure about the generator outlets.
