Can roadway fixtures be used for homes wired to code? « on: June 16, 2019, 08:48:44 PM » Author: Cole D.
I just wondering, if someone built a new home and had electrician wire it. Can the electrician use a cobra head or NEMA head or post top and have it pass inspection?

My understanding is the reason yardblasters have the closed top of the reflector around the bulb is so people can't stick their fingers in there where the wiring is. From reading instructions for them, the ones with the screw on refractors are considered UL listed, latch on might not be though because it has a larger opening around the bulb/ballast area.

So can these fixtures be used for residential or would they not pass inspection for the local electric code? I notice roadway fixtures don't show a UL or ETL logo on the tag.

Back when NEMA MV fixtures were the standard HID offering for homeowners here in Canada, they had the latch on optics with a hole just large enough to let the mogul lamp holder through. Not sure about the utility ones, though. I have a large hole one that I got at a local salvage yard, though.

Nowadays, NEMA heads are almost impossible to come by at suppliers, but whatever yard blaster bucket lights are available all have the small hole and screw in optics. They don't even have the "ears" to latch optical assemblies.

Not sure in Canada, but Lithonia/Cooper has the 11L series of NEMA heads on eBay, which have screw on optics, but also have the ears so they could use latch on. In instructions for GE 201SA it also lists screw on optics as an option, and I think the one I have has mounting holes for one. But I haven't seen any that actually have one.

I had also seen a vintage yardblaster on eBay from American Electric similar to what you describe. It had the latch on reflector but smaller hole around the lampholder.

Since I gotten into collecting, I prefer NEMA heads with latch on optics, since it looks more like a utility fixture.

Install whatever luminaire you want after the inspection...problem solved. Grin (And follow code in your install as much as possible for your own safety, and for the welfare of others.)

Your mission - should you choose to except it - is to save unique and rare HID lighting before it's all scrapped.

I cant see why it would be a problem. If youre pulling all the stops and putting up a real pole and arm bracket for the fixture it should pass, especially if you have it properly wired from underground going to the panel in your house or garage.

For what it's worth my post 1980 cobraheads have CSA listed (equivalent to UL listed in Canada) on the nameplate and the ones from the 1990s and newer even have a plastic guard covering the ballast and terminal block area. I believe the guard is a Canadian thing as I've only seen it in Canadian CSA listed cobraheads.
