Yes, you can, you just can't have 100 amps running through the box at one time. For instance, I have a 450 amp box in my house, but all the breakers add up to 900.
# 4 copper wire short distance.
A #3 copper wire with an insulation rating of 75 or 90 degrees C is rated at 100 and 110 amps consecutively.
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.
Yes, # 4 AWG copper and 100 amps is the max.
A #3 copper wire with an insulation factor of 75 and 90 degrees C is rated at 100 and 105 amps respectively.
# 4 copper wire short distance.
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.

A #3 copper wire with an insulation rating of 75 or 90 degrees C is rated at 100 and 110 amps consecutively.
A #3 copper wire with an insulation factor 90 degree C is rated at 105 amps.
The amp rating for a 4/3 wire is typically around 100 amps.
The amp rating for a 4 gauge wire is typically around 100-150 amps.
The amp rating for a 3 gauge wire is typically around 85-100 amps.
According to the 2008 NEC Code Book a #4 AWG Copper wire is rated at 95 Amps @ 90C (194 F), 85 Amps @ 75C (167 F), and 70 Amps @ 60C (140 F). These allowable amperage ratings are based on the wires type of insullation.
This is a voltage drop question. A voltage at 30 amps needs to be stated to answer the question.
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.
The burners will most likely be 240V. By keeping the range at 240 volts it will use less amps that at 120V. Say a range and oven is rated at 9000 watts. Watts = amps x volts. 9000/240V = 37.5 amps. 9000/120V = 75 amps. As you can see at 120 volts the amperage is double over 240 volts. You would need a 100 amp breaker and #4 wire to accomodate the range on 120 volts.
