Conductors

In electrical engineering, the term "conductor" is used to described the electrical wiring (aka "feeder") that is used to supply power to electrical devices.

• Copper and Aluminum: The two most commonly used conductors

• This section will give information about copper and aluminum as conductors.




• Insulation for Conductors

• All electrical conductors are required to have insulation for protection.




• Colors for distinguishing conductor voltage

• There are different colors for determining the designated voltage flowing through a conductor.




• Chart for sizing copper conductors

• This chart will assist in sizing conductors and conduit in electrical systems.




• Circular Mils of commonly used conductor sizes

• All electrical wiring is measured and sized in terms of circular mils. This chart will show the circular mils for each recognized wire size.




• Insulated Conductor Types

• Electrical wire and cable that has insulation is classified by its use and location.




• Conductor Resistance

• Use these conductor resistance factors from NEC 2011, Table 8, Chapter 9 when calculating voltage drop.
