Not smaller than 3 AWG copper, or not smaller than 1 AWG aluminum. If this is a longer run (say to an out-building) than you need to consider line losses and go with a larger wire size.

There is more to the question than meets the eye. Is this a 100A residential service that you are feeding with the wire in question? Is it a breaker for a sub-panel at a single family residence?
If a Dwelling Service, according to NEC Table 310.15(B)(7), 4AWG copper or 2AWG aluminum is sufficient.
If a sub-panel for a dwelling, you may be able to get by with the same, if the authority having jurisdiction (inspector) interprets this Table in that way.

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

The voltage of the load or appliance does not matter. If the total amperage is 100 amps, the total connected load (in AMPS) at any given time can not exceed that amount.
The formula you are looking for is I = W/E. Amps = Watts/Volts.

How do you compute the 2000 watts in 220 volt to how many amps?
watts = volts * amps--> Amps = watts/ volts therefore; 2000/220= 9.09 amps
How many amps is 6kW 240 volt single phase?
The equation that you are looking for is Amps = Watts/Volts. There are 6000 watts in 6kW.
100 watt is equal to how many va?
Since watts and volt-amps are different units of power, you cannot directly convert watts to volt-amps without considering the power factor of the load. In an ideal resistive circuit, 100 watts would be equivalent to 100 volt-amps. However, in practical applications with reactive components, the relationship between watts and volt-amps can vary.
What does half a volt equal in watts?
You need to know amps to answer this... Amps x Volts=watts
How many watts does my 12 volt 2 amp battery charger draw?
Your 12 volt 2 amp battery charger draws 24 watts of power (12 volts x 2 amps = 24 watts).
How do you compute the 2000 watts in 220 volt to how many amps?
watts = volts * amps--> Amps = watts/ volts therefore; 2000/220= 9.09 amps
How many amperes in a watt and how many watts in a volt?
Amps, volts and watts are interrelated, but you need to do a little math. Amps * Volts = Watts
How many watts in a 115 volt refrigerator?
How many Amps is the fridge pulling? Multiply the Amps by the 120V circuit you're plugging into and you'll get your Watts.
How many amps is 6kW 240 volt single phase?
The equation that you are looking for is Amps = Watts/Volts. There are 6000 watts in 6kW.

How many amp in 10000 watt 220 volt?
10000 watts / 220 volts = 45.4545 amperes
How many watts does my 12 volt 2 amp battery charger draw?
Your 12 volt 2 amp battery charger draws 24 watts of power (12 volts x 2 amps = 24 watts).
500 watts at 120 volts equals how many amps?
1000 watts at 9.5AMPS in 120 volt = 4.7 AMPS in 240 volt ..........Divide that by 2 according to the choice of voltage... 500 watts (120V) + 4.7Amp
How many watts can a 250 volt circuit run at 30 amps?
The formula you are looking for is W = I x E, Watts = Amps x Volts.
How many watts in 1 ampere 230 volt?
Watts = Amps X Volts Grab your calculator!
Is there a way for coverting amps into watts in a 12 volt applacation?
To convert amps to watts in a 12-volt application, you can use the formula: Watts = Volts x Amps. Therefore, in a 12-volt circuit, if you have 1 amp of current, the power consumption would be 12 watts (12V x 1A).
