Temporary lighting


Hi,

I have a ground floor store and would like to hand some temporary lighting (probably Par38 cans) that come with a cord and regular plug.

Is it a violation of the national electric code to simply run extension cords to the nearest plug (which would mean several running a 100' cord, with a few cans fed by each cord)?

Thank you,

Joseph

Could you please click on your username and update basic information about where you are located?

Light fixtures as you describe usually come with stranded lamp cord that is not suitable or safe for the situation you describe whether allowed or not. And connecting them with extension cords just compounds your problem.

Your insurance company and local fire and building inspection departments would cringe if they knew you were thinking about this. And at least the fire department will make you remove the extension cords if they see them during an inspection most anywhere in the World?

Why not consider some inexpensive track lighting for your store? Basic track is cheap (about the same as what you are thinking of paying for all the extension cords). You can position lights anywhere along the track. Unless you are a space alien and walk on ceilings you cannot trip over it.
Simple track canister lights for a lighting track will will cost you no more than what you are thinking of paying for lamp cord things.

an easier way is to buy a temporary light string from your electrical supply store. The main thing to make these safe is the lamps must have a lamp cage to protect from contact with live wires if someone breaks the bulb. The fixtures you suggest are not legal. The fixtures sdsester are not legal

Extension cords


Thank you both so much for the response.

SDSESTER: The cans do come with wires with plugs. What makes them not suitable or safe or legal?

BOB: I don't know what a light string is, but it sure sounds like an extension cord with light sockets in cages attached.

Is track lighting also not safe, suitable and/or legal?

I understand that if I hire an electrician, he would run solid conduit. I know that light fixtures can (should) be hard wired.

I'm trying not to spend the thousands it would cost for an electrician to run lights, when they're just temporary anyway.

I need lights that provide a lot of directional light to the walls.

Thank you,

Joseph (NYC)

yes you have the idea. What you want for temporary wiring is the bulb must be protected. And there is nothing wrong with plug ends and nothing unsafe about using a light with a plug or using extension cords.

Par38 Cans


I just want to make sure I understand:

I've attached a picture of the fixture I'm thinking about using.

It comes with a pigtail and plug, and I would run extension cords tacked across the ceiling and down the walls to an outlet.

The bulb is inside and even if it somehow breaks, it can't touch the wiring.

Does this clarify things?

Is this a safety violation? Code violation? Will the fire-dept/insurance-co/building-dept freak out?

Thank you again very much!

I found the string lights online, and I see how they would be easier and cheaper, but I think they would not provide the light where I need it.

Yeah, I was thinking you were doing construction/remodeling & wanted temp lights

How long will these Temp lights be up ?
7 days...30 days...90 days..a year ?
When talking about seasonal outdoor lighting most say 90 days is temporary
Different Building Depts may have a different interpretation of Temp

How heavy are these & will they be securely fastened to a joist ?
I'd be more worried about one possibly falling

Best bet is to check with your local Inspector & find out what they want
Unless you are OK with them possibly walking in one day & shutting you down

Also be aware that smaller gauge 100' extension cords carry less power
A normal 16g cord over 100' will have a ~10v voltage drop with 1200w of lights
Using CFL's would help reduce the load greatly depending upon how many lights you will have

Temporary


Not sure how long they'll be up -- at most a few months.

They're 2 lbs each and I'd be screwing them directly into the 3x10 joists.

I was planning on using a couple of 12/3 extension cords, so each cord would have less than 1000 watts through it.

I'd love to use CFL's, but I need the better halogen light.

Not so practical here in NYC to ask a local inspector or the DOB.
