Awg #6
Copper is preferable to aluminum and the size of wire should be the same or the next size down if copper is used.
Normally wire is sized by the amperage of the load. In this case the wire size is calculated by knowing the length of the run to the load and the amperage of the device to be connected. By knowing the length, the wire size has to be increased to allow for voltage drop over the distance from the supply to the load.
Overheating of electrical wiring is overcome by installing the correct size conductors to carry the load amperage of the equipment. Use a larger size wire to the load. The main purpose of the breaker is to protect the wire that is connected to it. If the wire becomes overloaded due to a high current flow the breaker will trip.
Depends upon how many amps you need at the load and whether you're using copper or aluminum or some other material, and how much voltage drop your load can withstand during startup inrush.
70 amps.
AWG # 8
Depends on the load it will carry which you failed to list.

The wire size is large enough to carry the load current and that the cord is properly voltage rated.
In the electrical trade aluminum wire is equivalent to copper wire as it is also used to carry current. To carry the same current as copper wire aluminum wire is up sized to meet the same ampacity.
Wire is sized by the amperage of the load. Without knowing what the load amperage,the voltage and whether the load is three phase or single phaseat the dock, an answer can not be given.
Yes it is wired with copper 2 wire is also known as 14/2 wire is use for switches,outlets,lights. and a 15a outlet should only be on a 15a breaker the main power feed to your meter to your panel is aluminum and can take more of a load than copper. In the US, 15 amp receptacles can be installed on 20 amp circuits if there is more than one receptacle on that circuit. Copper wire can carry a larger load than aluminum wire of the same size.

a fuseable link is just a length of wire that will carry a certain load. check the awg (american wire guage) ratings and install that size wire at the power source of that circuit
Yes, a #10 wire will carry 30 amps for 30 feet. If the load is rated as continuous then the wire will have to be derated to 80% capacity which will leave you with 24 workable amps. If the load demands currents higher that 24 amps then you will have to go to the next wire size up which is a #8 which is rated at 45 amps.
2 AWG.
The amperage flowing through a wire is directly related to the load placed on the circuit, and has nothing to do with wire size, except that a larger wire will carry more amperage. Increasing wire size will not lower amperage but will allow the circuit to carry more amperage if the breaker is also increased in size. No. Ohm's law tells us that V = IR. For a given load, R is constant, and thus the only way to reduce current is to increase voltage.
