I have three 400w metals halides (110 volt) wired together on a 20amp circuit all to theirselves. I am using one of those timers from home depot that cost about $40.00. If I have to add another 400 w light, it would need to be on a different circuit than the other three. My question is: could the 4th light be wired into the same timer or will I have to get a second one? It's not like I can just call an electrician. I can do a little home wiring but I'm no expert. b
You have the right idea, 4 -400 watt hid lights would be really pushing it especially if your tried to have them all witht the same start-up time on one circuit. Wiring a new circuit is as easy as 1, 2, 3, black, white, green. I recommend Wiring Simplefied, I have one of those rare 40th editions, just saw them at one of the big box stores for $5.95. I used the information n that book to install new 200 amp service and wire my area.
There are a couple of thread in this forum that electricians have started were you can ask more specific questions. DO you have any free space in your main breaker box? VV
