What size wire for 480VAC 75amps less than 10 feet?

For a 480VAC circuit carrying 75 amps over a distance of less than 10 feet, you would typically use a minimum of 4 AWG copper wire, or 2 AWG aluminum wire, according to the National Electrical Code (NEC) guidelines. However, always consider factors such as ambient temperature, insulation type, and conduit fill when selecting wire size. It’s advisable to consult local codes or a qualified electrician to ensure compliance and safety.
