How many amps will 600 volt wire carry?

Answer 1

It depends on how thick the copper part of the wire is. A good guide is 5 amps per square millimetre of cross-section, less for a permanent installation.

There are two factors that have to be taken into consideration when talking about wire. When amperage is talked about, that is the capacity of the wire to carry the current of the load, which is discussed above. When wire voltage rating is talked about, that is the resistance factor of the insulation wrapped around the wire to withstand the voltage that is applied to the wire. The higher the applied voltage to a wire, the higher the insulation rating has to be. Most conductors fall into three categories, 300 volts, 600 volts and 1000 volts. The 300 volt rating covers home wiring as it will never get above 240 volts. The 600 and 1000 volt rated wire is usually reserved for industrial installations.

Answer 2

AWG # 6 copper wire will carry 55 amps for service entrance wiring.
