Initially, the facility Engineer at the place where we are upgrading their parking lot lighting to LEDs, wanted us to use one leg, of the two 277VAC legs comprising their 480VAC feed from the street transformer, and cap the other one off. I soon learned that this was not according to code here in South Florida, and have had a 480VAC LED made for us in China. However the LED reasonably comes with a L (line) and a N (neutral) connection.
Question: "Can the two 277VAC feeds simply be joined to feed the 480V the LED requires or is it more complicated?"
At my business I join 2, 120VAC lines from different fuse boxes to make a 240VAC feed so provably not different but wanted to check before doing something wrong to a customer's electrical system.
