Tables based on values from NEC, Tables 310.16 and 310.17 and NEC, Chapter 9, Table 8 Conductor Properties.
NOTE: Motors and control boxes are designed to operate on 230V systems. Systems with low line voltage, between 200 – 207 volts require
the next larger cable size than shown in the 230V charts. If using a 3-wire motor with control box on a low voltage application switch
to a 208V start relay. The 208V start relay order numbers are found on control box repair part charts in this manual.
Temperature Conversions: 20º C = 68º F, 30º C = 86º F, 60º C = 140º F, 75º C = 167º F, 90º C = 194º F
