Hello everyone.. I'm thinking i'll probably need either 2 1000 watters or 2 600 watts.. in any case, it will be a lot of power running, as i'll also need outtake, and most likely a/c in the summer. What sort of things do I need to do to make this operation safe? The electriction just installed some of those bathroom safe outlets, 3 of them in the room, but do I need to change the breaker or something?

Since you haven't had any replys I'll try and help.
I'm in Auatralia and we have 240 volts here. Each power point circiut is rated at 15 amps. If you have 2kw running that's about 8 amps. For safety reasons you shouldn't run more than 75% of a circuits capacity. 8 amps is a little over half which is fine. Leaves plenty of room for exhaust fans etc.
BUT!... you need to account for other power hungry devices on the same power point circuit, like fridges, microwaves, heaters etc. To work out what elase is pluged into that circuit, plug a small light into the power point and turn the breakers of one by one untill the light goes out. That way you can work out which breaker it's on. When you turn that breaker of, see what else stops working and you'll know that they're on the same circuit as your Grow lights.
DON'T PUT BIGGER BREAKERS IN!!!!!!!, there that size for a reason. If you put bigger breakers in you will be able to draw more current without it tripping, but the cable is not rated to carry more. So it'll get hot and start a fire. Not a safe thing to do!.
Hope this helps

Kiefer : need more info , room size (too see what wattage ), the plugs your use'n to power this room are they on they same breaker?, also what else is running on the same breaker ( turn it off and see what don't work , then add those amps in ) .... adding breakers is more complicated , but sometimes that can be done , depending on if there are blank spaces in the panel (first of all ) or a good electric guy could run two stings of lights and plugs on one breaker ( if they are both overpowered , most of the time they are ) all depends on what is running on each one ... as for the GFI's , one is all you need at the begining of the string of lights and plugs , having more just causes problems with loads ( cold starts with high amp lights will pop them , if your right at the 15amp limit ) .. i did a bar for a friend and put 4 in a row for the beer coolers ( was outside and all metal coolers ) , so they ran fine till they had to restart , he called in a "Real" electrician , he replaced the GFI's except for the first one , but in doing so switched a few wires and the coolers shocked you and the track lights didn't work right , just goes to show , I messed up , so he came and messed up and they guy finally called the power co and they fixed his mistake
hope this helps

check my hey ppl under the stairs thread above this 1 i think you could adapt the design for your needs or may spawn a idea. as for your circut breaker i would have at least a 40 amp maybe even 60 amp wired just for that grow erea.

In my rooms I have built, I always pull a 220v run into a new sub panel to handle the lights, pumps etc. I use a 30 amp breaker for each outlet. Havent had any problems.
