AC Connections are a 3 or 4 wire connection. In 4 wire
systems incorporating a Neutral there will be the follow-
ing connections; Line-1, Line-2, Neutral, and Ground. In
3 wire systems not incorporating a Neutral there will be
the following connections; Line-1, Line-2, and Ground.
We recommend the following conductor cross-sections
for cable lengths up to 60 feet:
– blueplanet 1502x: AWG 12 up to AWG 4
75°C Copper Wire
– blueplanet 2502x: AWG 12 up to AWG 4
75°C Copper Wire
– blueplanet 3502x: AWG 12 up to AWG 4
75°C Copper Wire
– blueplanet 5002x: AWG 8 up to AWG 4
75°C Copper Wire
Larger cross-sections should be used for longer leads.
