Electrical Questions

[suedoe]

I know that people hate giving out electrical advise on here, and rightfully so, but I have a few electrical questions that do not concern any "how-to's".
I am going to have an electrician run all my wiring I am just not sure what I should have ran. Here are my questions...
1. I am wanting to run my lights and fans on 220v. I know Lumatek offers 220v for their 600 watt digitals. I am having trouble finding fans that run on 220v. Any advice?
2. I want up to (4) 600 watters and fans on one breaker. What size circuit should I have ran for this?
3. I also plan on having A\C and one day co2, should I also run 220v to the portable A\C? What size circuit would be suitable for these two?
4. What size circuit should I use for everything else? Like the pumps and such...

1. You dont need fans to run on 220, i dont think they are wired for that anyway unleast you live over euro.

2. You can do this, you can have 240/120 recepiticles on the same breaker just run a x-3 wire and use one of the black/red wire as a hot wire.

3. Depending on your ac how powerful it is, if you add everything up and if everything can be handled on your wire then you can run your ac along with your wires you hooked up to your lights, this isn't recommended because everytime the compressor kicks on it eats alot of juice. If you do your math right and you still have plenty of load left over on your wire then your safe to do 5 240 recepticle and one goes to ac.

4. Just use your regular house recepticle.

thanks that def. points me in the right direction. When doing the math do I just add up the amps each piece uses? Then add another 20% and that tells me the size circuit to run? I never even thought about being able to run 240/120, lol. I don't know why I figured they had to be on differenet circuits. Thanks! The Lumatek webstie states that their 600 240v digital ballast is only 2.75 amps? Is this true, I thought it would be much higher...

its wattage / 240 = amperage

thanks again! Is that just for 240v? Is it the same for 120v? watts / 120 = amps?

 

[wafflehouselove]

correct, that is why running 1k light on 240 its half the amperage then on a 120. 120+120=240 =)

wow, it all makes sense now! people told me i should run my lights on 240v and i was trying to figure out the reason why, thank you so much!

If you want the capability to expand your grow, I would suggest having the electrician install a sub-panel in your grow area, then take the circuits you need from the sub-panel. In the long run, this would be your most efficient and cost-effective solution.

i was thinking about doing that, thanks!
