To answer this question the voltage of the oven must be stated. Also double check on the wattage of the oven 3.55 watts seems low. Maybe it should be 3.55 kWs. Amps = Watts/Volts.
No. A 20 amp breaker needs 12 gauge wire.
A 30 amp breaker run 75 feet would require you use AWG #10 wire. But, an oven normally pulls more that 30 amps and I would not use #10 wire on a 30 amp breaker for an oven. Normally any newer oven is wired with AWG #6 gauge wire on a 50 amp circuit breaker so the breaker will not trip during heavy use of the oven. Some older ovens could use a #8 wire on a 40 amp breaker.
Hard wiring something is when you terminate the device or equipment directly with the cable/wires that are coming from the panel. Say for example: You have a 40' length of 10-3 M.C. cable (or similar) coming from your panel to feed power to the oven. In the case that the oven needs to be hard wired , there will be a junction box in the back , bottom, portion of the oven or an insulated cord with uncapped wires hanging out in which (either way) you need to splice the 10-3 cable to the wire ends of the oven inside that junction box (or the junction box that is installed in the wall). If the oven didn't need to be hard wired than you would normally install a 30-60 amp receptacle/outlet in a 4x4 box in the wall and you would terminate the 10-3 cable to it and the oven would come with a cord and plug that you would just plug into the wall. So, an easy way to think of it is: If the equipment needs to be hard wired than it will not have a plug on the end of the cord/cable. And if it doesn't need to be hard wired than you will just plug it into an outlet.
A 12 gauge wire can support a load of approximately 2200 watts.
All depends on how big your main breaker is and what size wire you are using,one 20 amp outlet needs #12 wire not more than 50feet away from main breaker
# 6 wire
No. A 20 amp breaker needs 12 gauge wire.
The recommended gauge size for a 20 amp wire in a residential electrical circuit is typically 12 AWG (American Wire Gauge).
Yes, a 20 amp breaker requires AWG # 12 copper wire. A 15 amp breaker requires AWG # 14 copper wire.
The recommended oven wire size for safe and efficient operation is typically 10-gauge wire.
4 gauge
60HZ 3 WIRE AC ONLY 14.0 kW @ 120/240 10.5 kW @ 120/208 Model No. 790.94469073 I don't know average, but the text above is what the label said.
Connect the white wire from the European oven to the white wire in the US receptacle. Connect the black wire from the European oven to the black wire in the US receptacle. Connect the green wire from the European oven to the bare wire in the US receptacle. The green wire serves as the ground wire since you don't have a separate ground wire in the US receptacle.
In an oven. The "hot" wire is in series with the ove thermostat and provides an isolated circuit for turning on the oven element(s).
18 gauge

You should use a 4 guage wire. There is a handy chart located at http://www.the12volt.com/info/recwirsz.asp which lists the proper wire size for differing wattages.
