Yep. These are common around here on 6' cantilever brackets as seen here. This one's 100w MV like pretty much all of the M-250A2 FCO here. There was another one of these two poles down the road, but it was replaced by a 50w HPS M-250R2 a few years back.
You'll also notice, the grid requires quick disconnects on the supply wires before the going into the bracket. They also are not responsible anymore for the light being transferred to a new pole, the town or towns electrical contractor also took that responsibility over.
The city owns the light, arm, hardware the arm is attached to the pole with, and the wires going up the arm, right? But how does that work with metal pole lights (i.e. underground). I assume the city owns the whole poles, but does NGrid own the foundations? Or does NGrid only own the wiring up to the manhole and the city owns the pole, foundation, and wiring from the manhole to the light?
I'm actually really looking forward to seeing what kind of mast arms Providence, Cranston, and other soon-to-be LED cities will use. NGrid has mostly just stuck with the 2" HAPCO 6ft upsweep arms, with the occasional used tapered elliptical or truss arm reused (I've seen new truss arms used in Massachusetts though). I'm also interested to see what Providence and other cities with underground utilities will use to replace knockdowns for their metal poles.
Yes that's correct, they own everything even including the wire up to the secondary. That's why NGRID requires the disconnect so the lights can safely be disconnected for maintenance purposes. As for underground installations, if they are like us then the town is responsible for everything including foundations. Here we only supply the feed to the foundation if it in one of our handhole/manholes. I know one town we serve who has owner ship of their lights has there own underground system for lighting that we feed from a common junction so at that point we have nothing to do with the wiring unless it's a problem at the junction. I'm going to assume the grid follows the same routine.
Wow amazing NGrid was willing to let the lights go at $1 a piece (including the poles, foundations, wiring, etc.). The price was set by the PUC based on the idea of the original value of the lights minus depreciation, but $1 still seems low to me. NGrid could have gotten more if they wanted it. I'm thinking they just want out of the street light business altogether and are glad to have less to worry about, since power distribution should be their main focus IMO. And here I thought RI was safe from LEDs because NGrid was so insistent on not offering LEDs.
Instead the state said "Don't wanna offer us LEDs? Fine, F*** you! We're going to own the lights now!"
I actually find it weird that NGrid doesn't already use disconnects on all their lights. Would make it a lot easier to shut off power to the light for service, but I guess shutting the power off would only be necessary if the fixture needs to be replaced, which isn't always the case with HID but likely will be with LEDs unless the PC is a dayburner. Not much you can do to fix an LED street light other than replace the driver, but the technology is advancing so fast that odds are, when the driver fails in 5 years you won't be able to buy the same driver. Not that places would bother with the effort anyway, but at least with HID the ballasts and lamps are all standardized.
