The wire size chart below shows allowable ampacities of insulated conductors rated up to and including 2000 volts 60 c through 90 c 140 f through 194 f not more than three current carrying conductors in raceway cable or earth directly buried based on ambient air temperature of 30 c 86 f. And skin coloured in plain colours to sans 1411 part 2. Wire is sized by the american wire gauge awg system.

Insulated with pvc. You must use the correct size wire for the current load requirement of the circuit to prevent the wire from overheating. For the wiring of industrial buildings housing control. Today we are here with another comprehensive copper and aluminum wire size calculator as we have discussed in detail the topic of how to calculate the proper wire size for electrical wiring.

Single phase voltages are usually 115v or 120v while three phase voltages are typically 208v 230v or 480v. Wire gauge refers the physical size of the wire rated with a numerical designation that runs opposite to the diameter of the conductors in other words the smaller the wire gauge number the larger the wire diameter. Common sizes include 14 12 10 8 6 and 2 gauge wire. High conductivity annealed stranded copper conductors to sans 1411 part 1.

The number and type of electrical devices connected to a circuit determine the ampacity requirement of the conductor. Amperes enter the maximum current in amps that will flow through the circuit.
