I was doing a rough wall inspection today when the electrician approached me with a question. The job I am inspecting is planning to use those cheesy temporary light strings (the ones with SO cord and yellow lampholders with a plastic cage) for their permanent lighting!!! He says that the other stores of this type have used them and had no problem. I asked him to present me a cut-sheet on them so that I could look it over. I realize that cord cannot be used to replace a wiring method (which I think is the case). Any thoughts on this? Thanks in advance for your replies.

I have seen this type of lighting in Macaroni Grill restaurants. I came to the conclusion that they must have been low voltage lights due to the 2 wire system that I saw. Will they actually be 120 volt stringers??

Any of these sets I have worked with are labeled as "Temporary Light String".
I would think 110.3(B) would prevent the use of these for permanent lighting.

Bob, as always thanks for your reply. He stated that they are listed. My response was exactly what you said, a U.L. stamp doesn't mean you can do what ever you want with them! He claims they are some sort of special cord that is approved for this, that and the other. I am quite anxious to see what the cut-sheet says about them. I highly doubt I'll approve them.

Here is what the UL White Book has to say about Temp Light Strings. TEMPORARY LIGHTING STRINGS
(XBRT)
This listing covers temporary lighting strings which are rated 20 amps,125 volts, intended for use indoors and outdoors to provide temporary illumination in accordance with Article 527 of the National Electrical Code.
Temporary lighting strings consist of a factory assembly of flexible cord, cable or insulated open conductors incorporating a series of Edison base lampholders provided with lamp guards. The flexible cord may be terminated at one end with an attachment plug, for connection to the source of supply, and with a cord connector at the opposite end. If an attachment plug is not provided, the temporary lighting string is provided with instructions for proper connection to the source of supply. I was just working with some of these and the UL tag that said TEMPORARY LIGHTING STRING was on the cable itself, make sure the contractor does not rip these off before you see them. Good Luck, Bob

I'd wait to see specs. I can certainly beleive that there might be a product like this for permanent installation.
