How many amps in a 220 volt 10000 watts?

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.

3 AWG copper for typical residential applications.

The formula you are looking for is I = W/E. Amps = Watts/Volts.

Power

= Current x Voltage

= 100A x 220V

= 22000W

Depends on the size wire and breaker used.
