In the United States, the National Electric Code dictates the depth of buried electrical lines. You have not provided enough info for me to give an accurate answer. For instance, some cables are manufactured for direct burial, that is to say without a conduit. Other considerations would be whether or not you are crossing a driveway, or alleyway. However, the maximum depth required is 24 inches to the top of the conduit or cable. Under certain conditions this depth may be reduced to 18 inches to the top of the conduit. Thank you for your desire to make a good installation.
There is no rating for #14 wire in the electrical code book. This is because #12 aluminium wire is rated at 20 amps and that is the minimum of home wiring circuit wiring in aluminium. It is not, if at all, used anymore. #10 at 75 or 90 degree C is rated both at 30 amps. #8 at 75 or 90 degree C is rated both at 45 amps.
about 3 or 4
70 amps.
10
100-200 Amperes.

Aluminum 4/0 wire car carry 180 amps at at 75 degrees Fahrenheit or 205 amps at 90 degrees. .

101 amps for chassis wiring and 37 amps for power transmission. This is for short lengths of wire.
depends on the amperage. 14 AWG for 15 amps, 12 AWG for 20 amps, 8 AWG for 50 amps.
You are probably thinking about 1/0 wire (1 ought wire). In copper it is rated at 175 amps and in aluminum 125 amps.
A 15 amp circut will be fine.
Maximum amps for chassis wiring : 101 amps Maximum amps for power transmission : 37 amps Reference : http://www.powerstream.com/Wire_Size.htm
445 amps. For example Mulberry AAAC cable.
