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 2-wire sizing chart above is only for use with PSC type, 2-wire motors.
Temperature Conversions: 20º C = 68º F, 30º C = 86º F, 60º C = 140º F, 75º C = 167º F, 90º C = 194º F
