480 Volt 3 Phase Wiring Sizing. Web a 480 to 208 is a 2.3 ratio. The calculator i used gave me 3 awg copper wire in 1 inch rigid but on our electrical contractors proposal he has 2 awg copper wire in 1 1/2 conduit.
480 volt 3 phase motor wiring diagram from groover.sch.bme.hu
Web the calculator is designed to accept the total line voltage and current of the combined three cables. The ampacity of the load side conductors must be a minimum of 1/3 the value of the primary side overcurrent device—or 23.34 amperes in this case—multiplied by the primary to secondary voltage ratio of 2.3. A = \frac {\sqrt 3 i \varrho l} {v} a = v 3i ϱl.
When Wiring A 480 Volt 3 Phase Motor, It’s Important To Use The Correct Wiring Diagram.
