Product Description

Copper Wire Resistance and Voltage Drop

Copper Wire Resistance and Voltage Drop

AWG stands for "American Wire Gauge" and is a standardized wire gauge system  used in the US since 1857 for diameters of round, nonferrous, electrically conducting wire.  The cross-sectional area of a wire determines it's resistance and current-carrying capacity.  The large the wire diameter, the less resistance it has to the flow of electrons, and the more current it can carry without overheating.  The table below list copper wire resistance for various gauges of copper wire.  These should be used as a rule of thumb as there are other factors that play into the current ratings of wire including ambient temperature, insulation temperature limit, air convection, etc.  You should consult the National Electrical Code (NEC) for specific guidelines.

The diagram below shows many of the common copper wire sizes used when wiring a home.  General ampacity ratings are listed as well but you should consult the tables below for more accurate ampacity ratings.  This illustration is meant to show relative sizes of the common gauges of wire.

 

Common Copper Wire Sizes:

This cable provides the amperage rating for common insulated conductors including RX.  Insulated conductors should have the temp rating and type (i.e. THWN 75ºC) printed on the outside of the cable.  You can then follow the chart below to see how much current you are allowed to put through the conductor.  This table assumes not more than three conductors in a raceway or cable or earth (directly buried) and is based on ambient temperature of 30ºC (86ºF).

 

Why do I need larger gauge wire to carry more current?

The larger the copper wire size the less resistance and hence the more current it can carry without over-heating. Resistance impedes to the flow of electrons and causes a voltage drop across the wire.  You want to avoid voltage drops on your wiring as much as possible because they generate heat and wasted energy.  The calculator below will help determine how much voltage drop you will get with a given copper wire and its associated resistance.

 

USE:

The specific characteristics of this conductor are it is fire retardant, and self-extinguishing. It is recommended for lighting and electricity installations in residential, commercial, and industrial buildings.

 

CONSTRUCTION

  1. Flexible bare copper conductor, soft temper, Class 1.
  2. PVC/A Insulation 70°C – extruded thermoplastic compound based on PVC, its  specific characteristics are, it is fire retardant and fire self-extinguishing.
  3. PVC/A 70°C Insulation – extruded thermoplastic compound based on PVC, with special fire retardant and fire self-extinguishing characteristics. Good finishing characteristics and easy sliding of wires through the electroducts.
