I work in an industrial plant as a PJ. I am preparing to sit for my PS. My question is, can you make up extension cords using cord caps. My supervisor said we can only use molded plug extension cords per NEC. The only reference that i can find is 590.6 a and b. I can not find a reference that states you have to use molded plugs only for 110 volt extension cords.

Thanks have a great day.

I have worked for companies like that, manufactured cords only "per NEC". When I questioned the safety director he admitted "We blame the NEC because it is easy, the but the restriction is actually just a company policy to prevent repairs to damaged cords".

THere is no NEC article stating you cant make your own extension cord using a connector and plug, 5-20p and a 5-20c for example.

Sorry, couldn't resist. :grin:

No NEC violations. It may, however, be contrary to your company's safety policy. And welcome to the zoo.

PJ-- I believe besides pajamas is a plant journeyman's limited license--This license allows the holder to perform an electrical installation, or repair, replace, or maintain electrical wiring and electrical products on or in an existing and operable manufacturing or industrial plant that is owned or used by the license holder's employer.

PS- is a plant supervisor limited license-- This license will permit the holder to direct, supervise, or perform the making of any electrical installation, except a service, in or on the manufacturing or industrial plant that the regular employer manages or owns.

It is compliant.

If the cord, whether molded or field constructed, is used for construction, maintenance, or demolition, and not used exclusively with GFCI protection, we need a "written assured equipment grounding conductor program". 590.6(B)(2)

I try to write the date tested directly on the cord, every 90ish days. :roll:

I'd say the only time it would be grey would be if there were no cable markings on the factory cord so you'd be putting a cord cap on a unknown type of cable. That's really stretching it. If your company wants to buy cords every time a cord end is damaged more power to them.

Commercially cords are used with less finesse. Strands and/or phase conductors can easily get pulled out of the terminals. This can likely happen on the load (female) side of the cord causing arc-flash or electrocution, but it can certainly happen on either end as well.
