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 ...

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 ...

If you’re getting ready to do some electrical work at home, it’s important to know the wire sizes you’ll be working with. Using the correct size wire facilitates proper electrical flow and prevents ...
