30a breaker 2-400w and 1-600w-will it be enough

[Lurch Farmer]

I have a single pole 30a breaker, and a 2 pole 30a breaker and 2 20a breaker, the breaker box sit less than a foot outside the room.
question is will this be good with 2-400w and 1 600w lights with off set timers
thankyou in advance

Are you running your ballast for the 600 on the 220 breaker?

You can run two 400w off one outlet

Use a different one for the 600w and you should be fine, that's not too much.

 

[Lurch Farmer]

Are you running your ballast for the 600 on the 220 breaker?

I will probably run it 110.
As I am a seeker of knowledge would there be a benefit to running it on 220 ?

 

[JJ Bones]

220 would lower the amperage

Thank you ,My dryer dyied and was replaced with a gas model. Would this outlet be useable for thi aplication?

a 1400w in lights on 240v is about 7 amps, no need for a 2P-30 amp breaker. IMO it's best use one closer to the load drawn also you can use smaller wire if you use smaller breaker (saves money). I'd get all the equipment(lights,timers fans etc ) together to see what's best before deciding breaker.

yes, but i would remove dryer receptacle and use it as a junction box and run 12/3 wire to wherever i needed to go (making sure the breaker was off, first i am also in NE US - not many cannabis friendly states, well, at least not mine, anyway

I wouldn't use #12 awg wire on a 30 amp breaker since #12 is only good for up to a 20 amp breaker. if something goes wrong the wire could burn before the breaker trips, you don't want your grow found due to a electrical fire. the ampacity of different wire sizes is #10=30amps or less,#12=20amps or less,#14=15amps or less, #16=10amps or less.

Amps X Volts = watts.
30 amps X 120 volts = 3600 watts
You don't want to push breakers too close to their load maximums. Can really screw up your grow by popping the breakers plus of course the fire danger from wires over heating.

sorry-i guess i neglected to mention i would also downsize to a 20A breaker. 30A is a bit much for lighting
