A. Voltage not unnecessarily high
High voltage are undesirable if the employees working around the circuits are not familiar
with electricity. Usually there is no advantage that would warrant a very high voltage in a
plant employing non electrical men.

The company is constructing a maintenance shop located 225 feet from the main plant electrical system. You are to install a 400-ampere three-phase wire system in the new maintenance shop. The service is supplied by the existing plant service. The voltage is 480 volts and the voltage drop is to be kept at 3% or below at full load. The conductors are to be aluminum. What size conductors should be installed for the new service? Express your answer to the nearest standard wire size. (Note: Determine the wire size by calculating length, resistance, and voltage drop as opposed to using the National Electrical Code.)arrow_forward
