As with any electrical installation, the wire size used depends on the expected maximum current the wire will carry. That cannot be determined by voltage alone.
The size of conductor needed will be a #14. It should be copper and have an insulation factor of 90 degrees C. The fact that it is a three phase load does not enter into the calculation of the wire size.
No a 208 volt outlet does not need a neutral. 208 volts is the line voltage between any two legs of a three phase 208 volt system.
A 500 MCM copper conductor will limit the voltage drop to 3% or less when supplying 350 amps for 150 feet on a 208 volt system.
what size wire would be required for an ak012 with a power supply of 208/240-3-60 hz
The wire size depends on how much current it will conduct.
The recommended wire size for a 220 volt circuit according to the 220 volt wire size chart is typically 10 gauge wire for a circuit with a maximum of 30 amps.
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.
The size of conductor needed will be a #14. It should be copper and have an insulation factor of 90 degrees C. The fact that it is a three phase load does not enter into the calculation of the wire size.
The recommended wire size for a 220-volt electrical circuit is typically 10-gauge wire.
The appropriate wire size for a 220 volt 30 amp circuit is typically 10 gauge wire.
The recommended wire size for a 30 amp 220 volt circuit is typically 10 gauge wire.
For a 220 volt circuit with a 30 amp capacity, the appropriate wire size would be 10 gauge wire.
No a 208 volt outlet does not need a neutral. 208 volts is the line voltage between any two legs of a three phase 208 volt system.
A wire size of 250 MCM will limit the voltage drop to 3% over a distance of 200 feet.
For a 220 volt circuit with a 40 amp load, the appropriate wire size would be 8 AWG (American Wire Gauge) copper wire.
For a 30 amp 240 volt circuit, a wire size of 10 AWG should be used.
For a 240 volt 40 amp circuit, the appropriate wire size is typically 8 AWG (American Wire Gauge) for copper conductors.
