Ground / earth protection will not impact cable sizing.

Cable sizing is based on amperage of the load. The rating of the capacitor bank and the voltage at which it operated need to be stated to give an answer.
The main purpose is to reduce cross-talk between the cable pairs. It also has the happy side effect of keeping the cable pairs neatly together while making connections..
Wire sizing is based on the motors full load amperage. The amperage can be calculated but a voltage has to be stated. I = W/E. Amps = Watts/Volts. Restate the question with a voltage and an answer can be given.
Ground / earth protection will not impact cable sizing.
A copper cable transports electrical signals. An optical cable transports light signals.
copper cost more to mine then aluminum so aluminum will cost less then copper cable.
It depends on the length of th cable and the diameter of the copper cable used.
The correct size of cable depends on the length of the cable run, as well as the voltage and current. Another consideration is what voltage loss is acceptable ? Safest answer would be to use a cable sizing table or online tool: http://www.solar-wind.co.uk/cable-sizing-DC-cables.html Hope that helps. G.

Copper cable with PVC insulation
Cable is 100% copper, and connectors are Gold Plated. No one uses silver or gold for the cable part.
Yry means copper round armoured cable
Fiber optic cable is constructed out of glass or plastic, and uses light pulses to transmit data. Copper cable is made out of copper material (not glass or plastic) and uses electrical voltages to transmit signals.
