For 10-2 wire, you would typically use a 30-amp breaker. This size breaker is commonly used for 10-gauge wire in residential electrical installations. Make sure to check your local electrical codes and the manufacturer's recommendations for the specific application.
A 3-wire circuit could have different amp ratings depending on the type of wire and the application. In residential settings, a common amp rating for a 3-wire circuit is 20 amps, which is typical for general-purpose lighting and outlet circuits. It's important to consult the local electrical code or a professional electrician to determine the appropriate amp rating for a specific 3-wire circuit.
A 220V 30A circuit typically requires three conductors: two hot wires and one ground wire. An additional neutral wire may be needed depending on the specific electrical configuration or equipment being used.
For a 240V 30A circuit, you would typically use a 10-gauge wire for the neutral conductor. It's important to follow the National Electrical Code (NEC) and any local regulations when determining the appropriate wire size for your specific installation to ensure safety and compliance.
For a 220V 50A welder, you would need a minimum of 6-gauge wire for your extension cord to ensure it can handle the current safely. It's recommended to use a heavy-duty, outdoor-rated extension cord with appropriate wire gauge and length to avoid voltage drop and overheating.

No, changing the outlet and breaker does not change the voltage of the circuit. To convert a 110V circuit to 220V, you would need to rewire it with proper gauge wire rated for 220V and install a compatible 220V outlet and breaker. It is important to consult with a licensed electrician for this type of conversion to ensure safety and compliance with electrical codes.
Yes, as long as the fuse or circuit breaker is rated for the smallest wire in the circuit, which in this case appears to be the 14 guage. Suppose the 14 guage is rated for 15 amps and the the 12 guage is rated for 20, and there is a 20-amp breaker on the circuit. Now suppose you have a short that draws 18 amps. The 14 guage wire will burn and catch fire, yet the breaker will not trip. That could be dangerous.
Have an electrician wire you a proper line for the appliance. You were just kidding about the 100A, right? 10, or 20amp, not 100.
You have to replace the wire (as you are increasing the current capacity), the outlet, and the breaker. Essentially you have to remove the old circuit and put in a new one. You can't reuse parts of the old circuit as you are increasing the current capacity and they would be underrated.

It would have to be a 30 amp breaker to use the full power of the welder. I'd say go with the 30A. The general rule is that your planned load should only be 80% of the circuit capacity. That means a 30A circuit should have a maximum load of of (30*0.8) = 24A. With the 30 amp breaker you must have at least #10 wires feeding the circuit.
The NEC limits the overcurrent protection of #10 copper to 30A. This means that that a continuous load supplied by the #10 cannot exceed 24A unless the breaker is rated for 100% continuous duty. Don't forget to apply any derating factors as required in table 310.16 of the NEC. For derating you can use the appropriate temperature rating column i.e. 90 deg for THHN dry location but in no case can you exceed 30A. It depends upon What type of wire and how that wire is being run. Standard ratings for residential wiring is a maximum of 30 amps for a #10 wire. To get technical, I think the maximum amperage of #10 wire run enclosed (like in metal conduit) is 33 amps. Most building inspectors will go by the 30 amp rule. 10 copper wire will hold 30 amps /we use this size wire for electrical dryers. For aluminum wiring the maximum loading is lower. 10 gauge aluminum hold 25 AMPS.
