Electrical Wire Gauge For 20 Amp Circuit

Electrical Wire Gauge For 20 Amp Circuit. If you plan on going over 100 feet, or if you want to run the wire in conduit, you should upgrade to 10 gauge copper wire. In most instances, the size of cable should be printed on the sheath, but if not you will need to calculate the diameter of the wire to determine its size, which means working out the area of a circle e.g.
