Wire Sizes and Insulation
Wire sizes for grounding (earthing), current, voltage, and contact
connections are dictated by the terminal blocks and expected load
currents. You can use the following table as a guide in selecting wire
sizes. The grounding conductor should be as short as possible and sized
equal to or greater than any other conductor connected to the device,
unless otherwise required by local or national wiring regulations.
