Infinity would know best but I think he mentioned GFCI protection for temporary ONLY applied to lighting accessible to the public.

The NYC amendments to the NEC are in post #9 and #20. I don't recall a GFCI requirement for temp stringers coming out of the NEC or as posted the NYC amendments.

OP, what does AHJ have to say about this? Did you get them involved? Is the job inspected?

Sorry, my previous reply was not intended for this topic. I meant to post it for the exhaust fan topic. :lol:

For typical NM style stringers with a pigtail and laundry drop every 12-15 feet I would say no GFCI protection required. It would be incumbent upon the person plugging into the laundry drop to provide their own GFCI device. Either by habit or spec we almost always use GFCI circuit breakers for the laundry drops.

Sidewalk shed structures have a lengthy list of requirements in NYC.

Good info but a few questions.

So then what drives the field to install GFCI breakers for laundry drops if not required by code?
The code isn't clear regarding GFCI for temp power drops, agree?
How the heck would someone plugging a power tool into the drop provide GFCI protection?

Thanks.

1- It could be part of the specification which was influenced by the insurance company. Then the EC is getting paid to install it.
2- It's seem clear that it's not required at the circuit breaker but required on the construction site. If it is required at the CB then someone needs to dig up a code reference.
3- A simple plug in GFCI from home depot or elsewhere.

In NYC nearly every site uses covered sidewalk bridges outside the building. The light strings are normally low enough that someone could grab them, if not climb up on the scaffolding to do it. As a matter of fact this is probably a situation where you would want to use reverse threaded light bulbs to reduce theft.

Heh, I thought this was an AFD joke, so I googled them. They exist. :blink: Never seen one. Real life is sometimes stranger than practical jokes.

Yes, left-handed thread. The pigtails have red and white leads instead of the standard black and white for normal right-handed lamps. We just stopped using the left handed ones because we switched first to CFL's and now LED's. Now we really need left-handed LED's because they're being stolen at an incredibly high rate. Left-handed lamps were traditionally used on construction sites because people kept stealing the standard right handed lamps.

Solution: don't use temp luminaires that accept medium base lamps. Maybe a light string with fixed LED's of some sort.

Even if you bought a string of lights you would then need to provide the power along with it so it's often easier to just make them up.
