Whether you're installing, extending, or rewiring a circuit, finding out the wire gauge and amperage you will need is a key first step. The gauge—or size—of the wire used needs to match the circuit's ...

Most wire or string is made with a circular cross section of some particular radius and diameter. The area of that cross section is the well known A = pi*R² which is colloquially pronounced as “pie ...

Whether scratch-building a complete wiring harness or lengthening kit-supplied wires, you need to determine the correct electrical wire size needed to support each electrical device. The wire must ...

There are two main considerations for sizing DC wiring from the output of a power supply to its load. They are ampacity (fancy term for the number of Amps) and voltage-drop (remember ohms law: V = I x ...

Finding the right wire gauge and amperage is essential when installing, extending, or rewiring a circuit. The wire gauge, or thickness, must match the circuit’s amperage rating to safely handle the ...
