Electrical wiring keeps the power flowing through your home. It is run to power lighting, outlets, and devices throughout your home including appliances. Some wiring is low-voltage for things like doorbells, while other wiring is much larger for large loads to power things like ovens, ranges, welders, sub-panels, wells, and air conditioners. Here are some great articles about wiring.

Electrical wires have markings stamped or printed on the outside sheath of the cable. These markings tell what type and size of wire that you have. But looking deeper, the color of the wires inside of the sheath, like in type NM cable, will reveal that different color wires serve different purposes. Electrical wire color tells you a lot about the intended use of the wire.This coloring scheme is called wire color coding. Do you know what it means?

In order to install any electrical wire installation, the proper wire size for the application is needed. But how do you know what size wire to use? Wire is sized by the American Wire Gauge (AWG) system. Your installation of conductors will depend on a few factors. The gauge of the wire, wire capacity, and what the wire will feed should all be considered.

When considering the appropriate wire size for a circuit, don't forget to take the circuit length into consideration. Electrical wire, no matter what material it is made out of, has a certain resistance to it. With an increase in cable length, the resistance causes a voltage drop in the circuit.Continue to 5 of 8 below.

Bathrooms are damp and have special needs when wiring them. This article will help you install appropriate electrical wiring to cover lighting, air flow, and safety devices in your bathroom. Everything from watertight lighting fixtures in bathing areas to effective ventilation to GFCI outlets for safety should be observed.

Here are some great tips for determining the proper wire gauge, ampacity, and the maximum wattage allowed. Determining the proper size wire to use can be easy if you know what amperage and wattage a wire can carry per wire gauge. The trick is to have the right sized wired fitted to the power demand it will have on the circuit.

Electrical wiring to be run in conduit comes in individual strands, encased in insulation to protect the wire and insulate it from other wires and the conduit. Wires come in either solid or stranded, depending on the wire size. Bare conductors are available for ground wires only. The insulation is made to take on some rather extreme conditions. Heat-, oil-, gasoline- and water-resistant coatings are all available to help your electrical wire survive.

It is commonplace for homes today to have one or more of three different laundry circuits. Each has its own unique assignment for supplying power to the laundry appliances. One is a 20-amp circuit designated to run the 120-volt power for the washing machine and the control power for the dryer. This circuit can also supply general-use devices.
