Growroom Electricity and Wiring

Lol damn I'm born and raised Los angles california but moved her bout 5 years ago. I'd love to be back out there. If you ever up this way I will have you redo my whole room u let me know what the price is I got you.
 
Rives I'm heading to home Depot to grab the sub panel today.. is there anything you may think of I might need for this while I'm there,

They frequently don't come with a separate buss bar to keep the grounds and the neutrals isolated, so you may need one of them. Breakers to suit. Romex clamps.

I noticed that last time I bought one; why is that ?? And I ended up getting it all. From the sub panel to timer to subpanel .. could I use 10/3 for 30amp breaker ? The chart says I can.. just like your input trust your word then most sources lol.

I think that they leave the buss out simply because they can. More money.

Yes, 10/3 is fine for a 30a breaker.

It will on 240v, not on 120v.

A 1k light will pull roughly 1100 watts with the ballast losses included. 4400w/240v=18.3 amps. 4400w/120=36.6amps. You have to stay under the 80% rule for continuous loads, so 30a x 80%= 24 amps.
 
Ok the part I don't get though is its going to be 240 out of the box into the timer.. 240 out of the timer to the sub panel .. then I'm going branch it out to 115 at the breakers 20amp. So there for because I'm leaving the first panel is it considered 240 or because out of the last panel I'm drifting off to 115 is it going to be 115

you all are making me think (and I have little idea about what youre discussing) I'm going to burn my house down.. ignorance is bliss. "out of the box" is keeping me on edge.. no habla 240v. I'll read it all again.. I just had to whine a little.:tiphat:


EDIT: at least I have to try: street>>>Homes' main panel>>among all the other circuit breakers
there was one 1, 30amp/220v line that ran to a 30amp plug (was there when I bought the home) I split into 2, 15 amp lines with 2 15 amp breakers in place of the 1 30amp one..... I plan on running 2/600w on one of the 15 amp lines.. 911??!


EDIT: wait a minute.. youre in Europe? well hello anyway..:)

What counts is that the final devices are hooked up at 120v. Wattage remains constant, so if you double the voltage, the amperage gets cut in half. Conversely, if you cut the voltage in half, the amperage doubles. 240v takes two hot wires - your lights are running on one hot wire (half of the 240) and a neutral. Each of your lights is going to pull a bit over 9 amps if connected to 120v. They would only pull @ 4.5 amps if they were connected to 240v.

Ummmm.....

You replaced the 30a double-pole breaker with two single 15a breakers if I am understanding you correctly. A 600w fixture will pull roughly 660w total, so (2) of them will be 1320w. 1320w/120v=11 amps. The 80% rule says that you can have a 12a continuous load on a 15a circuit, so that part is fine.

The part that might not be good is that you will have both lights connected to the same phase. Overloading one phase (one leg of the 240v) can create a voltage imbalance that doesn't work well overall. This isn't a huge imbalance, but it really depends on how the rest of the loads are distributed in your panel - ideally, you would like the loads balanced between the two phases. Realistically, that rarely happens.
 
Rives so I have 6/3 coming out of the main breaker box I swapped out my 40 amp breaker and wired it to 240 60amp to my sub panel. At my sub panel I wired 40 amp 240 out to the timer (timer is rated for it). My next thing is to wire the lights at 240. How does it sound so far I have a turned the main breaker back on yet.

Sounds fine.

Be aware that #6, depending on the type of wire and insulation, is rated anywhere from 55 to 75 amps. The 55 amp wire is ok on a 60a breaker since there are no 55a breakers, and you can round up as long as the foreseeable current draw isn't above 55a. Yes, it is kind of a flaky rule....

does anyone know how to wire a building strait up to the mains power supply from outside?

Another person and I have a building that can fit around 30,000 watts of light power, but for obvious reasons we can not consume that much without drawing negative attention.
 
What I never understood is if you have enough money to buy a room with 30,000 watts of equipment.. why are you willing to risk you freedom doing it illegal. Your talking 20k just in lighting not Including anything else. If I had that type of money I would take a cruise and call it a day.

10-4 on the 30amp breaker=2, 15 ampers. 2/600 are good on one 15 amp line. amps phases ?? no habla.. better if I run one 600w on each 15 amp breaker? and run fans/pumps off each of those lines.. I'll be safer.:tiphat: thank you rives..

Are u talking about jumping ur meter?
I saw some video from an Asian gang grow op in Cali where they had used jumper cables to jump the meter.,,Sketchy shit and they got busted..
I'd look at diesel generators before Id considered stealing power... With all of the computer monitoring these days it won't take the electric co long to pinpoint the loss...
So yea, I second Rives post.. It's dangerous.. And prob a good way to get arrested and ur grow gear seized.
