Hey RIU! I posted a thread a few weeks ago about increasing ampacity in my garden area, and I may have just come much closer to a solution. I noticed a 50-amp rated 240v outlet (USA) in what used to be a laundry room, now a bedroom. I did some testing with the panel and it is the only outlet on an unused 30-amp circuit. It is also directly above my basement garden area.. I used a multimeter to confirm it is still getting 240v. Now I’m delving into a world of 240v extension cords and transformers and single phase vs double phase and I’m pretty stumped. I would like to run a maximum of 3 1k HID lights, 3 centrifugal exhaust fans, and a couple of room circulating fans on this circuit. Since it’s 30 amps at ~240v, I should have a max capacity of 7,200w, so practically around 6,000w. My question is, what equipment should I buy to make this happen? I could get an extension cord that plugs into this outlet (I hope!), and a step-down transformer, and run all of my lights and fans with the their current 3-prong 110v cords. I see some of the transformers on Amazon say they are for single-phase 240v power and not USA double-phase ... does this mean I can’t use them? I also see that all of my ballasts run on variable voltage and automatically detect what they’re getting from the wall. Would it be better to get 240v power cables for my ballasts? I would like to run my fans on the same circuit as the lights so there’s less chance my fans shut off and my lights come on and start a fire... but my fans only run on 110v. I feel like there’s a fairly simple solution here but I’m a little over my head. If any electrically-minded gardeners here could point me in the right direction, I would greatly appreciate it!
