E152A03.. 3 A
E152A06.. 6 A
E152A09.. 9 A
Note: All wire sizes are based on 75 °C (167 °F) copper wire. Higher temperature
smaller gauge wire can be used per National Electric Code (NEC) and local codes.
Recommended fuses 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 L1, L2 and L3 wires.
