for the parerall streetlighting system ( POCO) side useally 120 or 277 volts depening on the area the streetlighting hook up. also for the privte area like store parking lot lumaires system will varies alot most time i keep on high side if possible due the wattage and distance. most common are 277/480 volts for very large area but for smaller parking lots useally 120/208 or 120/240 depening on what the service system is set up. some case have to use the transformer to boost it up if the distance is pretty far.

most city dont have series street lumaire setup anymore.

someone in here ask about the light blub for series connetion set up. there are very few manfactures do still make it but will listed in specity appaction i.e. Aeroports , and few other specal listing there. if that person want to know where to find it let me know i can post it here where is the source for the odd ball lightbulb.

merci , marc

Simple system, tough to get your mind around. Your system can "shoot grounds" and still work perfectly well while being damned dangerous, wierd, huh?

If you're foolish enough to pull a ground wire in a pipe with your ungrounded conductors, your not gonna like what you get, even though it sure feels like you are complying with the code, it makes the situation extremely dangerous. That's about the worst thing that can go wrong

In Hiawatha, KS we currently use a 2300 volt 6.6 amp series street lighting system...... Our street lighting committee has looked into completely rewiring the system to parallel, but the cost at over $1.3 million seems incredibly high for 320 street lamps.

Over $4000 per light! [Linked Image]

In a nearby town we had a new supermarket open just over a year ago. During the civil engineering works for the new access roads, the local council repositioned a light on a small side street.

It's been standing there, no power, cover missing until about two weeks ago, when they finally got around to connecting it.

I guess it wasn't on their priority list....
