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.
A 4-gauge aluminum wire can typically carry up to 70-85 amps of current for general household wiring applications. It is important to always consult with local electrical codes and a professional electrician to ensure safe and compliant electrical installations.

100-200 Amperes.
A typical garage door motor uses about 3-5 amps while operating. This may vary depending on the specific model and size of the motor. It's important to check the motor's specifications for precise information.

100-200 Amperes.
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.

A 15 amp circut will be fine.
445 amps. For example Mulberry AAAC cable.
A #4 copper wire with an insulation factor of 75 or 90 degrees C is rated at 85 amps. A #2 aluminum wire with an insulation factor of 75 and 90 degrees C are rated at 90 and 95 amps respectively.
A 2000 MCM aluminum conductor with an insulation factor of 90 degrees C is rated at 650 amps. Parallel 500 MCM aluminum conductors with an insulation factor of 90 degrees C have the capacity of 2 x 330 = 660 amps. Triple 250 MCM aluminum conductors with an insulation factor of 90 degrees C have the capacity of 3 x 215 = 645 amps.
