Either #6AWG copper of #4 AWG aluminum wire rated for 90 c.
These values are rated at exactly 75 amps so you still need to calculate for voltage drop, conduit fill, and ambient temperature. So as a basic rule of thumb I always step up one wire size(#4awg copper and #3 aluminum) just to be safe.
It depend on what the load is. If it is a motor load then the size of the conductor has to be increased by 125% of the motor's full load amperage.
A #6 copper conductor with an insulation rating of 90 degrees C is rated at 75 amps. If the insulation factor is 70 degrees C then the conductor size is increased to a #4 conductor. If the insulation factor is 60 degrees C then the conductor size is increased to a #3 conductor.
Could use #4 Copper or #3 Aluminum, not taking voltage drop into consideration. You won't have to take voltage drop into the equation, unless your wire run is over 90 or 100 feet.
AWG # 4 copper unless you have a run over 100 feet.
14 for 110 volt and 12 for 220 volt
AWG # 6 copper.
That is 10 amp wire.
The ampacity or amp rating of all wire is rated by the size of the wire. NM (non-metallic sheathing) wire is no different. In household wiring 14 gauge wire must go on a 15 amp breaker/ 12 gauge goes on a 20 A and 10 gauge goes on a 30 Amp.

For a 220 volt 100 amp breaker, you would typically need a wire gauge of 2/0 AWG (American Wire Gauge) or larger. It is recommended to consult with a professional electrician to ensure the proper gauge is used for your specific installation.
A #14 copper wire with an insulation factor of 75 degrees C is rated at 15 amps.
That is 10 amp wire.
on a 4000 watt amp the best gauge wire woul be between 2 and 0
A #6 copper wire with an insulation factor of 75 and 90 degrees C is rated at 65 amps.
The ampacity or amp rating of all wire is rated by the size of the wire. NM (non-metallic sheathing) wire is no different. In household wiring 14 gauge wire must go on a 15 amp breaker/ 12 gauge goes on a 20 A and 10 gauge goes on a 30 Amp.
No, 10 gauge wire requires the use of a 30 amp breaker. A 20 amp breaker is only used on 12 gauge wire.
AWG #6 wire.
wire gauge is used to determine the size of the wire to be installed based on the amperage draw of whatever is being hooked up on the receiving end. ie 14 gauge is for a 15 amp circuit, 12 gauge is for a 20 amp circuit, 10 gauge 30 amp etc. to get specific amp draw ratings on a particular gauge of wire look at a current National Electric code book or ugly book.

A #14 copper wire with an insulation factor of 75 degrees C is rated at 15 amps.
A 30 amp breaker run 75 feet would require you use AWG #10 wire. But, an oven normally pulls more that 30 amps and I would not use #10 wire on a 30 amp breaker for an oven. Normally any newer oven is wired with AWG #6 gauge wire on a 50 amp circuit breaker so the breaker will not trip during heavy use of the oven. Some older ovens could use a #8 wire on a 40 amp breaker.
