Common sizes include 14 12 10 8 6 and 2 gauge wire. Also learn about what electric flexes and electric wires do and protected against overloading. Usually a general purpose house circuit is designed for 20. For the 00 000 0000 etc.

In the american wire gauge awg system wire size diameters can be calculated by applying the formula d awg 005 92 36 awg 39 inch. 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. Table of common electrical wire sizes and amps or fuse ratings residential sec cable other wire ampacities for 1 3 current carrying conductors in cable earth or raceway for 120 240 volt systems sized between 100 and 400 amperes. Amperage amps versus wire cable size mm to awg ul486e assigned maximum ampere rating versus wire size for copper conductors.

Single phase voltages are usually 115v or 120v while three phase voltages are typically 208v 230v or 480v. The gauge guide bullets will help you determine the overall size including insulation of an unmarked cable. Find out about cable sizes for electrical use in the uk and 1 5mm and 2 5mm and other electric cables and the current they carry. You must use the correct size wire for the current load requirement of the circuit to prevent the wire from overheating.

Wire is sized by the american wire gauge awg system. Amperes enter the maximum current in amps that will flow through the circuit. Awg to mm2 pdf. Electric cable sizes and amp ratings for the uk electrical resistance and cable rating tables.

Voltage enter the voltage at the source of the circuit. National electrical code ansi nfpa 70 1999. Check out our printable version pdf to more accurately measure the end of your cable against gauge guide bullets. The number and type of electrical devices connected to a circuit determine the ampacity requirement of the conductor.

Gauges you use 1 2 3 which makes more sense mathematically than double nought. For motors it is recommended to multiply the nameplate fla by 1 25 for wire sizing. Current is measured in amperes or amps.
