Service wire for 100 amps requires AWG #3 copper.
#6 wire stranded
AWG-8 wire can safely carry 30 amps to a load 100 feet away.
To calculate the wire size, a system voltage is needed.
A #2 copper wire with an insulation factor of 75 and 90 degrees C is rated at 115 and 120 amps respectively.
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.

cable size for 90 amps 3 phase 440 v <<>> A #3 copper conductor with an insulation factor of 75 or 90 degrees C is rated at 100 and 105 amps respectively. If this feeder is for a motor connection the wire size has to be increased to 125% of the full load amps of the motor.
To calculate the wire size, a system voltage is needed.
A #2 copper wire with an insulation factor of 75 and 90 degrees C is rated at 115 and 120 amps respectively.
2 AWG in Aluminium is required.
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 V stands for volts and A is amps. If for example you have a 12kVA device and are running off a voltage of 120 volts then Amps = 12000/120 = 100. You then use the calculated amps in a wire size table to get the correct size.
you Multiply 100 X 100 you Multiply 100 X 100
you would use #2 aluminum urd wire for a 100 amp service
