Powering 4 x 1000w. Plug in contactor? Bad idea?

[themjmd]

Hello.

I have nearly everything set for an 8 x 8, 4000w grow to be set up in the coming weeks. I have never worked with as much lighting power before and I want to get this right.

I will be growing in a garage. I am unsure of the current circuit in there but I guess its something like a ring main, as its common. Even though that is still not enough for 4000w + ventilation, reservoir pumps, controllers etc.

I have seen contactors to handle the load such as a 'Green Power 8-Way Contactor' which can apparently run 4 x 1000w lights or 6 x 600w lights. I am unsure of the saftey of these as they can be plugged for power by two regular plugs.

What would be the best way of powering these lights? I might add in a separate panel for the lights such as a CAP-8. I want this to be safe and efficient. I do like the idea of the plug in contactor, but it seems to good to be true.

Thanks all.

I don't think the Green Power 8-Way Contactor plugs into regular outlets.

Unless there is a 30 amp 220v dryer socket in the garage, your best bet is to run a 30-50 amp 220 volt circuit from the main to a sub panel or directly into 2 separate t104's.

4kw + Ventillation is no joke, and you will need some good equipment to get the job done without creating a safety hazard.

What LSWM said.

Best bet is to just run a new wire. A standard 15-20a 120v circuit isn't going to handle the load you want to throw at it. Even if the plug in contactor thing is rated for the load, the circuit in place isn't.

Run a 240v line for your lights and AC, use the 120v circuits in place for your fans, etc.
