Current is measured in amperes or amps. 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.

1 current ratings for up to 1000 v pvc insulated single and multicore wiring cables ambient temperature up to 30 o c values for resistance are based on electrical resistivity for copper 1 724 x 10 8 ω m 0 0174 μω m and electrical resistivity for aluminum 2 65 x 10 8 ω m 0 0265 μω m. Usually a general purpose house circuit is designed for 20. The higher the gauge number the smaller the. The tables below are intended to be a general guide for wire size and amp ratings.

It just calculates the voltage drop consult the above table for rules of thumb or your local or national electrical code or your electrician to decide what is legal. The number and type of electrical devices connected to a circuit determine the ampacity requirement of the conductor.
