Hey all, So I've been reading up a little on electricity capacity as I am completely naive on the subject. I need to check the amps and voltage on the breaker box and outlets but I was wondering if anyone has experience in placing over 3000 watts in a flower room. We are shooting for two 1000w HPS and two 600w hps to cover roughly 14'x10' to give more than adequate light. There are two to three outlets available that we can run into the room so I believe that we can safely put each 1000 on their own outlet and double up the 600's on the third. Any advice is helpful, I just want to be safe. Possibly want to toss in a 600w LED also Thanks for the input.
Comes down to amp draw. A 15 amp service is designed to carry a constant of 12.6 amp. That's 1512 watts per 15amp service. so you'd need two 15 amp services running to the room just to get your lighting. And may as well through in a third service for your fans and misc stuff.or go with a 20 or 30 amp service. All depends. you could run a 240v 15 amp line and split the outlet tabs to isolate top and bottom outlets and have 15amps per outlet. It'd be a little cleaner doing that but all pends bro. If you got any more questions quote me. I'm an electrician technician in training
I guess I should clarify. you don't go off the lights wattage. you go off of driver amp draw. my 400w hps driver draws 3.5 amp so 420 watts total.
Thanks dude, I might message you soon once I check all the amps and volts on the breaker box. Complete noob when it comes to this stuff :x
ya no problem. another thing I forgot to mention is wire sizing 14 awg is good for "15amps" 12 awg is 20amp and 10 is good for 30. I'm just not sure on length ran thought since you will lose voltage and amperage per so many feet given
Bottom line I would suggest a separate 20amp breaker for each light 2 outlets (4 plugs) available for each. I would hang each light off its own breaker while using the other open outlets for fans, dehumidiers, etc. If needing a heater/AC I would add yet another breaker. Although non-sensical math-wise. You are pretty safe to look at wattage of any unit and divide by 100 to estimate your amp needs. (i.e. 1000 watt light needs about 10 amps available)
No. Those outlets are all going to be on the same 15 amp breaker circuit. that means roughly 1500W MAX for the entire room. If you're going to want to use that much power for lights, you need to run them on a dedicated 30 amp 230VAC circuit. You'll need to get a qualified electrician to install that for you. The rest of the grow can run off the existing 115VAC outlets.
