If you have 100 amp wire, you can use it for a 60 amp circuit, or for any circuit of 100 amps or less.
But if you have a 60 amp circuit, 60 amp wire is thinner and cheaper than 100 amp wire.
Service wire for 100 amps requires AWG #3 copper.
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.
The fuse or breaker should be no bigger than specified for the wiring and devices on the circuit. Your nominal current draw may be 20 amps, but a short circuit would cause maximum current to flow which in this case would be 100 amps until the fuse blew.
Volts * Amps = Watts 12 V * ?Amps = 100 Watts OR ? Amps =100W/12V OR 8.33 Amps = 100W/12V Use a 10Amp fuse inline and you can get by with 16Ga wire.
The sizing of wire is calculated by the amount of current the circuit draws. To find the amperage when the wattage is known use the following formula, Amps = Watts/Volts. 6500/240 = 27 amps. A #10 AWG copper conductor will limit the voltage drop to 3% or less, when supplying 27 amps at 240 volts for a 100 foot distance.

# 4 copper wire short distance.
It depends on the application, but for Single-Phase dwelling service and feeders 3 AWG copper is good for 110 amps. That really equates to 100 amps since you can't get a 110 amp circuit breaker.

A #3 copper wire with an insulation factor 90 degree C is rated at 105 amps.
A #3 copper wire with an insulation rating of 75 or 90 degrees C is rated at 100 and 110 amps consecutively.
To calculate the wire size, a system voltage is needed.
Wattage is really what is needed. If you are working with DC voltage, Ohm's Law is at work. But to answer your question directly probably a #4 wire. <<>> To answer this question the circuit's voltage needs to be stated. Then a voltage drop calculation can be made.
