Cable Recommendations
Figure 9: Cable current handling table
For power distribution it is also critical that the cable is selected to minimise voltage drop,
especially during start up peak currents. It is recommended that the cable voltage drop
uses a peak current of 3A and a full voltage drop of <1V (including return) to select the
cable.

Length Versus Cable Size
All cables have resistance. When comparing cables of the same type and style, then
generally, the thicker the copper the lower the resistance for the same length.
generally, the thicker the copper the lower the resistance for the same length.
If cables are to be used over long lengths then it may be necessary to increase the cable
size to reduce the voltage drop caused by the resistance of the wire and the load current.

For the CP6100 wiring the following is provided as a guide to maintain an acceptable
voltage drop.
