A 300 MCM copper conductor with an insulation rating of 90 degrees C is rated at 320 amps. Parallel the feeders to obtain a total of 640 amps. This will be acceptable as service feeders for a 600 amp service.A 400 MCM aluminium conductor with an insulation rating of 90 degrees C is rated at 305 amps. Parallel the feeders to obtain a total of 610 amps. This will be acceptable as service feeders for a 600 amp service.
Loaded question, what is the voltage, run length, aluminum or copper feeders, expected constant load? Definitely bigger than 4/0
180 what?

A 15 amp breaker is not sufficient for a 225 amp load. You would need a breaker that matches the load current, such as a 225 amp breaker. Using a 15 amp breaker for a 225 amp load would cause the breaker to trip immediately due to overcurrent.
The 225 amps is the secondary output amperage. Look on the machines nameplate to find the input amperage. It is that amperage that is needed to size the feed wire and there the breaker size. When you find that amperage you may want to re question the breaker size.

For a 225 amp 208 volt 3 phase circuit, you would typically need to use a 3/0 AWG copper wire or a 250 kcmil aluminum wire. Be sure to consult with local electrical codes and regulations to ensure compliance with specific requirements for your installation.
In a three-phase 225 amp panelboard, each phase will carry 225 amps. This means that the total current flowing through the panelboard is distributed evenly across the three phases, allowing for a maximum of 225 amps on each phase at a time.
No, using 10-3 wire with 30 amp breakers is not suitable for running a 225 amp arc welder. The wire size and breaker amperage should be appropriately matched to the current requirements of the welder to ensure safety and prevent overheating of the wire. In this case, a larger wire size and breaker amperage would be needed to support the 225 amp maximum draw of the welder.

5 amp,10 amp, 15 amp, 20 amp, 25 amp, and 30 amp.
For a 225 amp 3-phase service, typically you would use 3 sets of 3/0 AWG copper conductors or 250 kcmil aluminum conductors for the service entrance conductors. Make sure to consult the National Electrical Code (NEC) and local regulations for specific requirements.
In a three phase 225 amp panel, there would be a total of 225 amps available for each phase, making it a total of 675 amps for all three phases combined. This means that you could have up to 225 amps of current flowing through each phase simultaneously.
A Lincoln 225 AC welder typically requires a 50 amp double-pole breaker. This ensures sufficient power supply and prevents overloading the circuit. It's important to consult the welder's manual or an electrician to verify the specific requirements for your setup.
