Wiring Question For 14 Light Setup

[dutchcrunch]

Hey whats up IC MAG people?

I currently have a 6000w barn setup w/ 24,500 btu a/c, dehuey, fans, vortex blowers (2) 6 a/c outlets running fans, water pump et...

I just built another barn I want to throw (8) 1000w lights w/ same size a/c also dehuey, fans etc.

I have 200a service. My question is, can I safely run both rooms at the same time, in essence a 14k grow w/ (2) 24,500 btu a/c's, dehueys etc..

I know there are some wiring/electrician pros out there!!

Thanks,
Dutch

It looks to me like you have roughly another 6kw of potentially continuous load in the a/c's. Disregarding everything else except the lighting (and including the ballast losses), that puts you at roughly 92 amps if everything is running on 240v. You are limited to 80% of the breaker rating for continuous loads (anything longer than 3 hours), so that puts you at 160 amps available from your service.

You should be fine.

Let's do the math!

6000watts barn #1 lights
8000watts barn #2 lights
100watts barn #1 dehumidifier (my guess)
1500watts barn #2 dehumidifier (my guess)
3800 watts barn #1 AC (running) (6000 watts startup) my guess
4500 watts barn #2 AC (running) (my guess)
Fans barn #1 1000 watts (my guess)
Fans barn #2 1500 watts (my guess)
4000 watts misc. other power consumption
===================
30,400 watts (total)

Assuming you have 230 volt service and 200 amp supply, that means you can supply 46000 watts.

Looking good to me!! You have about 15,000 watts in reserve. I would suggest you stagger the start times for both barns so that you aren't trying to ignite all the lights, AC, and fans at the same time. If possible, you might want to stagger each barn in two groups to even out the startup peak load. Instead starting all at once, barn #1 group A lights start, wait 10 minutes, barn #1 group B start, wait 10 minutes, barn #2 group C start, wait 10 minutes, barn #2 group D start.

Of course, you could just offset the light periods between two barns by 3 or 4 hours and not have such complicated startup. You could also offset the barns by 12 hours so that you are only running one barn at a time (assuming 12/12). This gets tricky to coordinate with independent timers. You might want to use a digital controller that can coordinate all the lights, fans, etc.

Rightthefuckon!! God damn I love you guys! quick answers! Yes R2k my man I plan on staggering both rooms. Im also going to be running Solis Tek 1000's in the new barn so they apparently wont fire until they have stable load, fairly dope no??

Thanks you guys, when i get to doing the wiring for the room Ill probably be asking more?'s. I have always hired electricians to do my grow rooms in the past this time I'm going to try to do it myself. I recently bought 2 pretty decent books on wiring. One is called "wiring a House" For pros by pros and the 2nd book is called "the complete guide to wiring" by black & decker. I have been reading them pretty solid for the last week & I think I can tackle this!

Use a PLC to control everything.
