Am coming out of the main switch gear in a hospital with a 480v 150a feed. The gear is in the basement. This will feed a new 208/120 panel on the 3rd floor via a transformer, also on the 3rd floor. The print shows the feeder going strait to the trans. Don't I need a disconnect here? Panel is main brkr. Also this panel will serve some isolated ground circuits. Does the ig have to go all the way back to the gear or can it stop at the trans? Articals?
