3/0 gauge
6 AWG will handle 50 amps with a voltage drop of about 4 volts. If you go to 4 AWG and limit to 50 amps your voltage drop will be 2.5 volts.
AWG # 14 is the smallest wire you can install in a home and it can only be used in living areas. It will carry 15 amps.
140 AMPS

A #3 copper wire with an insulation factor 90 degree C is rated at 105 amps.
A #8 wire with an insulation rating of 75 or 90 degrees C is rated at 45 amps.
A # 14 copper conductor will be fine to carry 8 amps at 120 volts. This size conductor is rated at 15 amps.
30 amps.

The ampacity of an 8 gauge wire at 240 volts would depend on the specific type of wire and the installation conditions. Generally, an 8 gauge wire can safely carry around 40-50 amps of current. It is important to consult the National Electrical Code (NEC) and local regulations for precise guidance.
Zero. Watts is the product of Amps x Volts. As you can see an amperage value is needed. Voltage = Watts/Amps. Volts = 200/? 20 volts
Generally 40 amps continuous or 50 amps surge is safe.
