so here we go 277 + 277 how on earth does that make 480 let me call up the old screen here we'll go to the screen and I'm gonna close my slideshow slideshow play from start okay so this is a wide system and if you want to know more you can go back through the feed and look at the Delta versus Y and how we have two different systems we're gonna talk about how the Y system here works so the Y system set up like a Y and again if you want to know more just go back and check out that video now what happens here is I've got three phases we've got a phase B phase and C phase and the way that this is connected you notice that a phase it's got 277 volts on it B phase has 277 volts on it and C phase has 277 volts on it but when you throw your meter if you go from a to there you're gonna read 277 but if you go A to B you're gonna read 480 so if you add up let me just add this upgrade 277 + 277 equ
