the first question is this 480 off of a three phase service nearby ? or is this just a single phase 240/480 secondary transformer?if the later is true why couldn't they just change the transformer to a 120/240 unit? usualy the power company will supply what ya need.also a 480 volt form 2s meters are made,i have one of these weird things,the guy that i got it from said it was for interstate lighting.
