28000 watts of madness

Haha Hush...I just changed out the filters in 2 of the rooms, 8 10" and 3 12". I gotta change them every year or so. You can sure tell when they start to go out

Hal, what does a room like that give you after harvest?

 

[robertr]

Those timers you have , they look like standard timers. I guess you don't need heavy duty timers because of the relays right?

A lot. Quite a lot.

Yes, those timers are just the "trigger" for the contactor. The load of the lights goes thru the contactor, so I just needed a 120 trigger to fire the contactor.

Its like having a relay to drive a relay. The difference is the first relay is a low current relay and the second relay is the high current relay. I see this in electronics a lot. If you don't have the little one to drive the big one, you will cook one.

 

[robertr]

Yeah I dealt with them a bit. Electrical is interesting.

 

[NorCalHal]

I love electrical. Bigger the show, the more challenging for sure. Easy to max out. Most bug shows I see are all 3phase.

Just remember that all the wires are filled with smoke. That smoke is what makes them work, and if you do something to let the smoke out of the wires :doh: they won't work anymore :hubba:

Hey Hal
I got a question for you, why do you vent if you have the co2 burners up and running?
Just curious as it was my understanding one doesn't need to change air when using co2....

Hey there Hal, killer looking set up...I am an electrician, love the use of contactors, and higher voltage fixtures.

 

[NorCalHal]

Hello Shecallshimthor..I actually do not vent the rooms at all. Venting is set up in case the AC goes down, but it is controlled by a separate thermostat to kick on if the temps get to 90. So, you are correct, you do not need to vent if you are controlling the temps/RH and co2 ppm.

Thanks lifespan, the electrical is the fun part...very important. I am usuing major juice, so it has to be done right.

The 3 phase panel will carry plenty and allow you to drop the power consumption when using the higher voltage taps on the lights. And of course it dropped the 5 ton ac unit's sla's from around 70 amps to 50 amps, as well as decreasing the rla' s too. You are probably close to using about half of the capability of panel.

 

[NorCalHal]

Yes lyfespan..I am under utilizing that panel...and it is killing me. I think this winter I will shut it down for a couple of weeks and redesign the rooms and make them bigger. I have space to fit maybe 2 rooms of 25 lights each. That will max the panel out pretty good.
Right now, I need all the production I can as demand is HIGH. Once the outdoor harvest hits and the market slows down, I can take the downtime and rebuild the rooms. Taking down the AC's air handlers will be the biggest pain.

Man NCH, I can't even fathom what your PGE bill is. Insane! If you spent that sorta cash at a vegas casino they'd be comping the presidential suite for you

Very nice NCH
