## What is SWG table?

British Standard Wire Gauge (often abbreviated to Standard Wire Gauge or SWG) is a unit for denoting wire size given by BS 3737:1964 (now withdrawn). It is also known as the Imperial Wire Gauge or British Standard Gauge.

**How do you calculate SWG of copper wire?**

Stranded wire gauges should be measured by calculating the equivalent cross sectional copper area. First, measure the bare diameter of a single strand and locate the circular mils value in the row that matches your measurement. Second, multiply the circular mils by the number of strands in the cable.

**Does AWG measure ampacity?**

AWG – American Wire Gauge One of the most important roles of American Wire Gauge is to measure the current carrying capacity in Amps of wire (aka Wire Ampacity = The amount of maximum current that a conductor can carry continuously without exceeding its temperature rating.

### How is SWG measured?

The thickness of a wire is often given as a Standard Wire Gauge, or SWG. This is number from 0000000 or 7/0 (thickest) to 50 (thinnest). The gauge of most wire used in electronics is between 20 and 30. Often, a wire gauge will be stated followed by “swg”, so 26 swg, etc.

**How do you calculate ampacity of a wire?**

Ampacity can be calculated by dividing the Wattage by the rated voltage. The quotient is the expected Amperage of the circuit.

## What is the purpose of Standard Wire Gauge SWG?

Wire gauge is a measurement of wire diameter. This determines the amount of electric current the wire can safely carry, as well as its electrical resistance and weight.

**How many watts can 18 AWG handle?**

600 Watts

Wire Gauge | Amperage Rating | Wattage Rating |

#18 | 5 Amps | 600 Watts |

#16 | 7 Amps | 840 Watts |

#14 | 12 Amps | 1,440 Watts |

### How is amp rating calculated?

To calculate amperage, use the equation Amps = Watts/Volts. For example, a 200W light bulb on a 120V circuit would draw about 1.67 amps. Calculate the TOTAL amperage rating of all devices. Make sure they DO NOT exceed 80% of the breaker’s total amperage.

**How many amps can 3 AWG wire handle?**
