its posable that 100amps direct burial cable (copper at your best) in my sugestion should be a minium size of 2/0 and ground size of #2 this is stepped up for voltage drop concerns.

For a 75 amp circuit with a 100 ft run, you would need a #4 AWG copper wire to ensure minimal voltage drop and to meet electrical code requirements. Using the correct wire size helps maintain the efficiency and safety of the circuit.
Using a wire rated for 100 amps for a 60-amp circuit is generally fine. It's important to ensure that the wire gauge matches the amperage requirements to prevent overheating and potential fire hazards. Check local electrical codes to confirm that it is within regulations.
For a 30 amp circuit running 100 feet, you would typically need to use at least a 10-gauge wire to ensure safe and efficient electrical flow. It's important to consult local building codes and regulations to ensure compliance.
That can't be answered until you state the voltage.
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.
