WHAT SIZE WIRE FEEDS A 37 KVA LOAD?

To determine the appropriate wire size for a 37 kVA load, you need to consider the voltage and the length of the run. For a typical three-phase system at 480 volts, you would use a wire size of approximately 6 AWG copper wire or 4 AWG aluminum wire, factoring in a standard ampacity and a 3% voltage drop. Always consult the National Electrical Code (NEC) and local codes for precise requirements and adjustments based on specific installation conditions.
