Why should I use good judgement when sizing conductors?
Good judgement should be used when sizing conductors because large conductors can become costly and difficult to install, while small conductors can cause potential danger . Use the calculator above to size wire for basic applications, or view some of the wire ampacity charts for wire ampacity values.
What is the difference between a single phase and a three phase circuit?
Single-phase voltages are usually 115V or 120V, while three-phase voltages are typically 208V, 230V or 480V. Amperes - Enter the maximum current in amps that will flow through the circuit. For motors, it is recommended to multiply the nameplate FLA by 1.25 for wire sizing.
How many wires are needed for a three phase circuit?
For three-phase circuits, four wires are required. One of these wires is a ground wire which can be sized down. To calculate ground wire size, use the Ground Wire Size Calculator. Insulation - Select the thermal rating of the insulation on the wire. Conductor - Choose the material used as a conductor in the wire.
What is the purpose of sizing electrical wire?
The National Electrical Code provides requirements for sizing electrical wire to prevent overheating, fire and other dangerous conditions. Properly sizing wire for many different applications can become complex and overwhelming. Amperage is the measure of electrical current flowing through a circuit. The ampacity rating of a wire determines the amperage that a wire can safely handle. In order to properly size a wire for your application, the ampacity ratings for a wire must be understood. However, many different external factors such as ambient temperature and conductor insulation play a part in determining the ampacity of a wire.
How does the cross section of a conductor affect the resistance of a wire?
However, the cross-sectional area of a conductor can also be changed to alter the conductor's resistance. By increasing the cross-section of the conductor (or increasing the size of the wire), the resistance decreases, and the allowable ampacity increases .
What is the measure of electrical current flowing through a circuit?
Amperage is the measure of electrical current flowing through a circuit. The ampacity rating of a wire determines the amperage that a wire can safely handle. In order to properly size a wire for your application, the ampacity ratings for a wire must be understood.
What determines the ampacity of a wire?
However, many different external factors such as ambient temperature and conductor insulation play a part in determining the ampacity of a wire. Wire ampacity is calculated in such a way as to not exceed a certain temperature rise at a particular electrical load.
