Does anybody know if there is a minimun height for ballast to be mounted on an approx. 40' parking light pole? We found one for voltages exceeding 277V. But not for 277V to ground and under.
Thanks

No minimum. But I have heard of a 40' maximum. . .for a 40' pole. 8) :idea:

Haven't you ever heard of a sky hook? That way you can place ballast above light pole. :p :p

I HAD thought of it actually. But then you would be mounting the light on the sky hook, not the pole. . .the joke wasn't as funny when I started adding disclaimers. :wink:

Good call though.

We are a microsociety of dorks. They were not having fun at your expense. Welcome to the forum. :D

I've never seen poles where the ballast wasn't mounted in the head. Where do the instructions show the ballast for this pole? Or is this an old existing pole?
 
I wish I had a picture...We replaced old merc ligts on 30' poles. The ballasts were in cans attached to the top of the poles with the arms about a foot below the top of the pole. The fixture heads were old, old cobra heads.
So it is possible...
 
Hey, sparky, if I had looked up to notice that this was your first post, I probably wouldn't have been such a wise guy right off the bat.

My bad. Uh. . .welcome to the forum :?: :!:

:shock:
 
I've heard stories of ballasts that were suspended inside the pole itself, but I've never seen them. The service guys were replacing these expensive ballasts one at a time; finally, they convinced him to install new poles with less expensive, more modern ballasts. It was cheaper in the long run (despite the poles they had serviced prior to convincing him to swap them all out). :)

Hey you can't say that about me. I may be a smart a##, but not many people accuse me of being smart.

What kind of pole is this? If it is a newer pole, they are usually set up with an opening for wires to come out to the lights. If it is an old wooden pole you can mount at most any height you want to. I would recommend staying up high enough to avoid lights getting hit by truck traffic though.

Welcome to the forum! Some of us try to use a bit of humor at times.
 
Remote ballasts are commonly used in Tennis court lighting and similar venues. They want to be able to take poles down and some actually will put up the "bubbles" during the cold season to extend tennis all year round. So those poles will come down. They are a lot lighter without the ballasts, especially the 4 head types.
In the winter the bubble will have remote lighting fixtures that need to be very light in weight, hence the remote ballasts.
 
i did see few place have remote ballast one place i did work on before

the trolley track have remote ballast and the lumiaire is shockproofed [ to withstand hevey viberations ] i done few of that

of course some old street lumiaires i did rember it clear with old mercury vapour system which it was wired in series [ i think about 1.5 KV open voltage ] with " series ballast on the post "

one city did have tons of very old style corba head with ballast on post and finally they change over to HPS for while then went to MH [ not too many pepoles like HPS colour at all]

one industrail building have remote ballast due the high heat evermonet so they put the ballast on the wall and ran the wires to the lumiaire

Merci, Marc
