5.2.3. Cabling

The current rating of the wires or cables used to connect the Lynx Distributor to batteries and/or the DC loads has to be rated for
the maximum currents that can occur in the connected circuits. Use cabling with a sufficient core surface area to match the
maximum current rating of the circuit.

For more information on cabling and cable thickness calculations see the 

Wiring Unlimited book
