The wire size for 600 amps on a single wire 1250 MCM. A 1250 MCM copper conductor is rated for 645 amps with an insulation rating of 90 degrees C. This size of wire is too large to handle easily when it comes to the terminations. A service requiring 600 amps is usually paralleled or tripled which reduces the wire size which makes the wire much easier to handle. For a parallel service two 350 MCM cables are used and for a triple parallel run three 2/0 conductors are used. These conductors all have an insulation rating of 90 degrees C.

For 600 amps, you would typically need at least a 250 MCM wire size to safely handle the current without overheating. It's recommended to consult with a professional electrician to determine the specific wire size needed based on the application and local electrical codes.
A 1250 MCM copper wire with an insulation factor of 90 degrees C is rated at 645 amps.
A 1500 MCM copper wire with an insulation factor of 75 degrees C is rated at 625 amps.
It depends on a few things:
1. What type of conductor e.g aluminium, copper etc
2. Length of conductor required
3. Aloowable voltage drop. usually 4%
For a device operating on 240 VAC pulling 22 amps, you should use a wire that is at least 12-gauge in size to ensure it can safely handle the current without overheating. It's always a good idea to consult with a licensed electrician to determine the appropriate wire size and type for your specific application.
For a 240 volt circuit at 40 amps, you should use 8-gauge wire. This wire size is rated to safely carry 40 amps of current and is suitable for most residential applications. Be sure to consult local electrical codes and regulations before undertaking any wiring project.
The amp capability of a 600 volt wire depends on its gauge or thickness. For example, a 12-gauge wire can typically handle around 20 amps, while a 10-gauge wire can handle around 30 amps. It is important to consult the wire's specifications or a professional electrician to determine the specific ampacity for your application.
The only thing you need to know in order to size your wire is the "5.1 amp" amount.Figure on the motor drawing double on startup, so say, 10 amps, or so.18 gauge wire would pack your 5.1 amps just fine, but it is a little flimsy . . . I would use 16 gauge, instead.Of course, the insulation on the wire you select should be rated for 600 volts or more.
We recommend using a #6 copper wire for the connection between the breaker box and the earth ground rod. This size wire is commonly used for grounding purposes and is sufficient for carrying the electrical current safely to the ground rod. Be sure to consult with a qualified electrician to ensure the proper materials and installation for your specific situation.
