12 AWG should be fine since resistance of wire is only about .16 ohms per 100 ft.
The size of the amp breaker for a 220V air conditioner will depend on the specific requirements of the air conditioner. As a general guideline, you can calculate the required amps by dividing the air conditioner's wattage by the voltage (220V). For example, if your air conditioner is rated at 5500 watts, you would need a breaker of at least 25 amps (5500 watts / 220 volts = 25 amps). It is always best to consult the manufacturer's specifications or a licensed electrician to ensure the correct size breaker is installed.
That would be a 40 amp 220v circuit. Circuit breaker is 40 amps and wire is 8 awg. Should use solid copper wire. Follow oven installation instructions.
To determine the cable size in mm2 required for 450 amps, you need to consider the current-carrying capacity of the cable. The exact size will depend on the type of cable and the installation conditions. For 450 amps, heavy-duty cables with a size of around 240 mm2 or larger would typically be used to ensure safe and efficient operation.
For a 3-phase 80A 220V load with an amp rating of 68, you would need a wire size of at least 4 AWG conductors. It is recommended to consult with a qualified electrician or refer to the NEC guidelines for specific wire sizing requirements based on your installation conditions.
A #6 copper conductor will limit the voltage drop to3% or less when supplying 30 amps for 175 feet on a 220 volt system.

Number 8. Wire <<>> A #8 copper conductor with an insulation factor of 75 and 90 degrees C are both rated at 45 amps.
At 20 amps the 220V will supply twice (2x) the power that the 110V will supply. The answer depends upon your meaning of the term 'better'. If you have a specific size load that you are supplying such as a motor that will accept either 220V or 110V then by using 220V you will have less of an impact from voltage drop and the conductor size will be smaller due to the current being 1/2 of the 110V. If by better you mean which one will give you the most power then the obvious answer is 220V.
50 amps
Group 34, 600 amps
That would be a 40 amp 220v circuit. Circuit breaker is 40 amps and wire is 8 awg. Should use solid copper wire. Follow oven installation instructions.

For 450 amps, heavy-duty cables with a size of around 240 mm2 or larger would typically be used to ensure safe and efficient operation.
The battery size depends on the size of the engine. The larger the engine size the more cranking amps are required. A small 12.5 HP will only require around 190 amps while a 22HP will require closer to 360 amps.
Service wire required is AWG # 3/0 copper.
For a 3-phase 80A 220V load with an amp rating of 68, you would need a wire size of at least 4 AWG conductors. It is recommended to consult with a qualified electrician or refer to the NEC guidelines for specific wire sizing requirements based on your installation conditions.
The recommended wire size for a 220v electrical circuit is typically 10-gauge wire.
