Wire Sizing Selection Tables

There are several factors that must be considered before determining the proper size wire to select for an application. Items you must consider are:

1. Source Voltage
2. Number of Phases
3. Horsepower or amperage of the motor(s)
4. Length of the Cable or Run

The charts beneath contain recommended minimum wire size (AWG) for different voltage, horsepower and cable length combinations. These charts are only a guide. Please consult the National Electric Lawmaking (NEC) and whatsoever applicative local standards for verbal requirements.
