Light System Lighting
You have been hired by company to connect an outside lighting system to a panel box located 55ft from the?
point of attachment. The conductors are to have THWN -2 insulation and the wire copper. The lighting system is rated at 20kw at 240v. What is the wire size needed to make this connection? Pleae show calculations with formula.
20,000 watts or 20 KW / 240 volts = 83.3 amps if this is total Kw on each phase and it is single phase system. (Which rated at 240 I assume it is otherwise it would be 120/208 or 277/480 wye 3 phase.)
55 feet from the panel or power feed is not a problem with voltage drop at 240 volts either. So # 2 wire cooper is good as far as the wire size goes.
Article 31-16 shows #2 wire good to 95 amps for the total load you are fine.
You have been given the answer and the formula here but if you want to get the W I R E formula you should know this one.

Near Infinity Light System- by Dr Stiffler
Does LED lighting work for artificial plant light?
I am growing some herbal plants that require a delicate balance of lights and nutrients. Unfortunately it's not always sunny where I from, so I grow indoors. I setup a LED blue/red 255 tiny light system 12x12 inch over the small flat of rosemary/chives...etc. How close should it be and will it be effective? I want first hand experience.
I start my plants (herbs, vegetables, etc.) every year in the house using plant lights, this year I switched to the "daylight" bulbs instead of the more pricey "plant and aquarium" bulbs, and they seem to be working just fine. The LED lighting won't work. I set my lamps about 8 inches above my seedlings and adjust as they grow.
