I have been receiving all sorts of different information regarding the following motor. I have a WYE start/Delta Run motor, 12 lead, 480 volts, single voltage, 150 HP. The starter (Wye start/Delta run) has two contactors for the connection of six motor conductors. There will be one 15' 2.5" raceway with 6-CCC and one EGC from the starter to the motor. What is the minimum conductor size? I came up with #1/0 but others have said #1, #4/0, and I have no idea.
