Control Wiring
Important points to remember about control wiring:
• Use Copper wire only. Wire gauge requirements and recommendations
are based on 75 °C (168 °F). Do not reduce wire gauge when using
higher temperature wire.
• Wire with an insulation rating of 600V or greater is recommended.
• Control wires outside the cabinet
should be separated from power wires
by at least 0.3 meters (1 foot).
