lighting circuits run a long distance are acting in peculiar way-a different set of lights come on every time we energize, making me suspect that not enough voltage is present to fire all ballasts at once---and then the other lights come on gradually. I'm wondering if this is due to voltage drop although we upped wire size to compensate. I wonder if and how sharing a neutral on these long runs affects the voltage drop situation. The lights are run through a contactor controlled by a photocell but I don't think that makes a difference. Any clues---help?

Re: voltage drop
Yes it sounds like voltage drop.
The multiwire branch circuits actually help overcome voltage drop.
If these fixtures are multi voltage I would see if I could run them line to line to drop the current.

Re: voltage drop
If your lights are wired line to line now and are on a 3 phase circuit, it sounds like one of the phases is out.
If you are running line to neutral on a multi-wire circuit on all the lights, it sounds like the neutral is broke, loose, missing.
What is the connected load? What is the distance?
What size wires did you run? What is the system voltage?
