Table 2 - Protection device and wire ratings
Note: All wire sizes are based on 75°C (167°F) copper wire. Higher temperature smaller
gauge wire may be used per National Electric Code (NEC) and local codes.
Recommended fuses/breakers are based on 25°C (77°F) ambient, maximum
continuous control output current and no harmonic current. Earth/ground wires
must be the same gauge, or larger, than the Line and Neutral wires.
