Avoiding circuit overload?

Alright, so I'm setting up my grow room and I have two 1,000 Watt MH/HPS convertble balast lights. Im no electrician but I think just one of these will use about 10 amps out of the 15 in my socket. Could I just get an extension cord and plug the other light into a different socket? Or do I need to do some heavy duty wiring?

Thanks
 
What are you doubting? I know one outlet wouldn't be able to handle two lights. I just wanted to know the best way to remedy that...Would it be ok to just use an extension cord and plug one of the lights in a socket in a different room?

first off M America or Europe? diferent wiring methods, since you guessed 10 amps for a 1k light, I will assume USA
you will need to know what else is on each breaker and add up the draw. several outlets will be wired together on 1 breaker. putting 10 amps to an outlet will be fine unless your lights are on & you plug a vacum into a different outlet that's on the same breaker. if you can find 2 outlets on different breakers and dont have a big load on them already, a heavy extension cord (no longer than needed)will work to get power for both lights.
 
Thanks, man, really appreciate the info. Yea, I'm in America. I was thinking maybe I could use one of the kitchen outlets cause I dont really need the fridge and I'm pretty sure that thing is on a 20 amp 240 volt circuit which would be ample for 2 lights.

Get a friend to help you map out the breakers. Turn on every light in the house as well as a lamp or something in every room. Stand at the box and trip em 1 by 1 and map what rooms/ plugs they control. As long as your lights are on separate breakers, everything is cool. Fridge is probably on 20 amp but is more than likely 110. Is it a normal looking plug? Washing machine plugs are good for lights too.

If you use extention cords - get the 15 amp Heavy Duty type.

Remember you ballast if going to add another 10-15%, extended duty ( longer than 2 hours ) on breakers is limited (advised) at 80% of rated capacity.

So 2000 @ 1.15 - 2300 watts ( not counting fans, etc)

A 20 amp circuit is good for 1600 watts of extended duty.

Good Luck :bigjoint:

I'm using 2 1000watt convertible hps/mh lights outdoors and I have extension cords running to two
separate rooms in the house on two separate circuits and they run fine. Took me 2-3 days to figure
it out.
