The following table defines
cable length guidelines for the various wire sizes that may be used for wiring
low-voltage (<30 V) input and outputs.
Note: The required wire sizes and lengths for high-voltage (>30 V) Relay
Outputs are determined by the load connected to the relay, and local, national, or
regional electrical codes.
