This at a recreation center parking lot. There are 3 other R37's and an OV-15 here that have their own PCs. I don't know if this Model 25 actually runs off that ballast anymore or not. All the lights are connected by spanwires. Either way its neat looking.
Those are overhead feeds. I guess the underground feed failed. I see they wired them up Boston Style lol. Here NGrid at least has the decency to run the new feed up inside the arm instead of taping it to the outside, which looks completely ridiculous.
Yesterday I saw a wire going from a 400 watt metal halide Cooper ovx spanning about 75 feet in length to 1000(?) watt HPS Spotlight pointed at a highway. The worst part was the wire was supported by just electrical tape on both lights.
Spot light or flood light? I assume the latter since it's a freeway. Utility grade electrical tape is much stronger than "normal" electrical tape, so for a temporary set-up I would say it's acceptable. It's probably just a 10 AWG cable so it doesn't way too much despite the long run. I wouldn't personally do it unless I had to though lol.
I think that thing that looks like a ballast can is a group relay. Perhaps it's only wired to the model 25 since it seems like it doesn't have a integral PC socket.
yeah, I've seen this can on poles before, looks like a photocell on top. Funny thing is I've seen it transfered from a shoebox without a photocell to a new pole + OVX with independent photocell.
One of the old utilities here used to do something pretty unique. If they had a flood light and street light on the same pole and the flood light would shine over the street light, they would install a shorting cap on the street light and wire the flood light so that its photocell controls the street light as well. When the current electric company replaces one of these street lights, they just use a photocell on the street light and wire the street light directly to the secondary feed.
Interesting, I wonder why they don't just reuse the shorting cap and use the existing configuration. I guess they might want to standardize how the lights are wired up though.
Yeah I'm not sure why they go through the effort of rewiring everything. I actually think they always replace the wiring going up the arm when they install any new fixture. Unsure on the policy on that, but it would seem like a good idea to replace the wiring each time they replace the light since they typically use THHN, which isn't sunlight-rated. Some of the lights I've gotten had the insulation on the wiring cracking right off! NGrid's new practice is to use liquidtight on the wire from where it exits the bottom of the mounting arm to as close to the triplex as possible, leaving just a few inches exposed to make the connections to the triplex, rather than free-fly the wires the whole way.
