Temp light

[kwired]

Ever seen the cord on a reel in an auto repair shop? They do it with both compressed air and line voltage. I had not heard the term "laundry drop" either but envisioned something to plug an iron into so you're not fighting the cord the whole time.

Legal? Who knows.
Convenient? Yes!

Those are generally listed cordsets though, and usually are cord and plug connected at the supply end as well, kind of making them not necessarily be a part of premises wiring and more of an appliance or utilization equipment, though they really don't quite meet those definitions either. But nonetheless is a listed assembly and is not a NEC problem as long as it is used within its listing.

Here is a photo of a few "laundry drops, and lamp pigtails".

Laundry drop is a slang term for molded receptacle on the end of a short piece of cord which is spliced onto a NM cable for temp power.

A visual analogy to laundry hanging on a clothesline perhaps? Especially if they are spaced along the length of the line rather than just at the ends.

female plug at end of string a lite

female plug at end of string a lite

was wondering on temporary lighting, If 100ft light stringer can have a female plug at the end. I know they sell them with a male plug on one end , but I have seen some which are capped at the other end and some with a female plug. Is this against any NEC codes? interestingly, they both have UL listings on them.thanks

On our projects we do not allow string-o-lite as they are way to labor intense to maintain. We use 1x4 or 2x4 fixtures spread out per the arch ceiling grid lay and height out to minimize the impact and confusion for the remainder MEP installation. It has been a cost savings to our owners by doing this as we inspect them, replace any lamps or ballasts, install them and send a laborer every morning around to check we have all lighting burning in the work space. We try and most of the time do, put all emergency fixtures (over doorways and spaced in egress pathways on their own emergency circuit fed from battery back up system or generator fed systems. This works well for us

Type, size and other project conditions do come into play here as well. Kind of tough for drywall finishers to finish a ceiling with temp lighting installed on it,
