Your house wiring works on the same principle, just on a larger scale and at higher voltages.May 6, 2019 · The Basics. First, understand the difference between wire and cable: A wire is one conductor that carries an electrical current through a circuit. A cable is a collection of wires sheathed together. The majority of conductors are copper, which is corrosion-resistant and works as a better conductor than aluminum. A thicker wire (with a lower AWG number) can carry more current without overheating. This is vital for preventing electrical fires. According to the U.S. Fire Administration, electrical fires account for over 6% of all residential fires. Ensuring you have the correct wire gauge is a simple step to reduce this risk. Common Wire Gauges and Their UsesLight switch wiring is a task that most DIYers can take on themselves without calling an electrician. Follow these steps to wire your switches safely. By Glenda …Neutral wires are always known as common wires. They also have only one color casing, unlike hot wires. In the USA, white is used for neutral wires.
