The amperage capacity of a wire is determined by the cross sectional area of the wire.

Another Answer

Electrical conductors are expressed in terms of their cross-sectional area. In Europe, for solid conductors, this is expressed in square millimetres. Stranded conductors are expressed in terms of the number of strands, and the diameter (in millimetres) of each strand, expressed in the format A/B (where A = number of strands, and B = diameter of strand) -from which the total area, in square millimetres can be determined.

In North America, the cross-sectional area is expressed in circular mils (round conductors) or square mils(rectangular conductors). A 'mil' is one-thousandth of an inch. A 'circular mil' is the diameter of a conductor, expressed in mils, squared -so it is not really a measure of area (as it doesn't take pi into account), but a figure that represents an area.

What size copper wire is equal to 0 aluminum?

Copper wire gauge sizes are not equivalent to aluminum wire gauge sizes. The gauge sizes for copper and aluminum wires are different due to their differing electrical conductivity properties. It is not possible to directly convert a copper wire size to an equivalent aluminum wire size.


How do you measure electrical current flow in a copper wire?

Electrical current flow in a copper wire is typically measured using an ammeter, which is connected in series with the wire. The ammeter measures the flow of electrons in the wire and displays the current in units of amperes (A). Make sure to set the ammeter to the appropriate range before taking the measurement.

What information can I find in a conduit and wire size chart?

A conduit and wire size chart provides information on the recommended wire sizes to use with different types and sizes of conduits. It helps determine the appropriate wire gauge for a specific conduit size to ensure safe and efficient electrical installations.


Why is a resistor called so?

I resistor is called so because it provides electrical resistance (measured in ohms). Electrical resistance describes how an electrical conductor (a wire) opposes the flow of an electrical current (flow of electrons). To overcome this opposition a voltage (a energy) must dropped (used) across the conductor (wire).


Is copper wire measured in circular mills?

Yes, copper wire can be measured in circular mils, which is a unit of area used in the electrical industry to specify the cross-sectional area of a wire. One circular mil is equal to the area of a circle with a diameter of one mil (1/1000 inch).

What is the electrical pressure that causes electrons to flow?

Voltage, measured in volts, is the electrical pressure that causes electrons to flow in a circuit. Voltage is what pushes electrons through a conductor, such as a wire, and is necessary for the flow of electrical current.
