generally size #6, but there can be factors which would require

up-sizing, such as high ambient temperature

long run causing excessive voltage drop

multiple circuits in same raceway

I would use 0/2 guage wire as it is about 1.4"2

<<>>

There is no such wire size as 0/2 AWG.

A #6 copper conductor with an insulation factor of 75 or 90 degrees C is rated at 65 amps. The wire's voltage rating is 600 volts on most specified wire so the voltage of 220 volts is well within the limits of the wire.

See Table NEC 310.16

but #6 copper is safe.

What size wire do you need to run 100 ft 75 amp 230 volt?

Depends on the size of the circuit which you did not list.


What size wire for a 230 volt circuit?

The size of the wire is set by the maximum current it has to carry. The voltage sets the size of the insulation. In the UK a 230 v (nominal) ring-circuit supplying a set of power sockets is rated at 30 amps and uses a ring of 2.5 sq-mm cable.


Can you use a 6 volt relay to 230 volt circuit?

If you are talking about a 6 volt coil, yes, so long as the contacts are rated for the 230 volt circuit. If you are talking about 6 volt contacts, no, absolutely not.

It is limited by the size of the fuse in the circuit.


Why won't a 230-460 volt motor work on a 120-208 volt circuit?

Because its designed to operate at 230-460, not 120-208.


What is the required wire size for a 230 feet run 480 volt 100 amp?

Depends on length. The more length, the more resistance.


What size cable for a cooker oven only max 2600watts?

On a 230-volt circuit, the cable should be suitable for 13 amps. The size is 1.25 mm2 or 1.5 mm2.


How can I get 230 volt single pole wire from my house panel?

In North America you can not obtain 230 volts from just one single pole breaker. The distribution is like this, from a one pole breaker to neutral is 120 volts. From an adjacent breaker to neutral is 120 volts. From the adjacent breaker to adjacent breaker (breakers situated beside each other) the voltage will be 230 volts.If you want to incorporate a 120 to 230 volt transformer into the circuit you can obtain 230 volts. The primary side of the transformer will be connected to the 120 volt circuit and the secondary side of the transformer will output 230 volts. The transformer must be sized to the load amperage or the load wattage of the connected 230 volt load.

Can a 440 volt capacitor be used for a 230 volt application?

No. The capacitor will short out and possibly explode. On the other hand, the 440 Volt Cap can be used in a 220 Volt circuit.


Is a 230 volt motor cheaper to run than a 115 volt?

No, a watt is a watt, the voltage only changes the wire size. The power company bills you based on kilowatt hours. 1hp = 746 watts, no matter what the voltage.
