Service entrance wire should be AWG #3 copper.
At that distance you will have a voltage drop of 81.25 volts if you use the recommended #6 wire on a 240 volt, 100 amp single phase circuit. Therefore I recommend you contact you electric utility and let them figure the voltage drop and the size wire required to safely run this distance. Using too small a wire can damage the electronics at the end of the run.
8 is the size of wire to use for grounding a 100 Amp panel. Green is color used for grounding8 is code.A #3 copper wire with an insulation rating of 75 or 90 degrees C is rated at 100 and 110 amps consecutively.
You need to look at the regulations that apply in your country. If in doubt, use a neutral wire of the same size as the live wire or wires.
6 AWG.
AWG 10.
The recommended wire size for a 100 amp electrical circuit is typically 3 AWG copper or 1/0 AWG aluminum.
A #3 copper conductor with an insulation factor of 90 degrees C is rated at 115 amps.
For a 30 amp breaker, you will need a wire that is at least 10 gauge in size.
6
For a dryer installation, you typically need a 10-gauge wire.
The wire size depends on the amperage, not the voltage. The fact that the welder runs on 440 volts does not affect the wire size! You need to ask this question instead: What size wire do you need for a three phase welder on an eight foot run if the nameplate amps are 45A?
Use AWG #6 wire.
For a 50 amp breaker, you will need a wire that is at least 6 gauge in size to safely handle the electrical load.
The size of wire you need for your electrical project depends on the amount of current the circuit will carry. Consult the National Electrical Code (NEC) or a qualified electrician to determine the appropriate wire size for your specific project.
The recommended gauge for 100 amp wire in a residential electrical installation is typically 3 AWG copper or 1 AWG aluminum.
At that distance you will have a voltage drop of 81.25 volts if you use the recommended #6 wire on a 240 volt, 100 amp single phase circuit. Therefore I recommend you contact you electric utility and let them figure the voltage drop and the size wire required to safely run this distance. Using too small a wire can damage the electronics at the end of the run.
you can use two hot wire different phases with a double pole braker .
