Question: Electrical Wire Sizes
What sizes of wire do I need to wire the various appliances in my home? This seems to be a common question asked on a regular basis. Let's examine some appliances that need tobe wired.
Electrical wiring is installed to provide a wide range of power options in your home. It is used for lighting, receptacles to power things like TV's, stereos, curling irons, and hair dryers.
The wiring also feeds a variety of appliances, both big and small, throughout the home. These include ranges, ovens, refrigerators, freezers, dishwashers, microwave ovens, washers, dryers, toasters, blenders, pizza ovens, coffee pots, and crock pots, just to name a few. Installing the proper sized wire is essential for proper operation and electrical safety.
The links below will help guide you through both wire sizes used and installation of many of these appliances.
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.

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. Although some wires look the same and even look to be the same size, it doesn't mean that they can handle the amperage. For instance, copper wire can handle more than aluminum wire and should always be your choice of wiring to install in your home.
Your home is wired with different types of wire. Each has its specific use to accommodate the load and conditions it is exposed to. Let’s examine what each type is and how it is used in the home’s electrical system.

Electrical wiring is rated in gauge for it's size and amp rating.
Electrical wire can come in rolls or on spools. Lengths of wire vary from standard cuts of 50, 100, 250, 500 and 1,000 feet, but can be special ordered for specific lengths. The homeowner will generally choose the shorter lengths, while the contractors chooser much larger rolls, knowing that they will use it somewhere down the road. The homeowners electrical jobs may be limited, unlike the contractor.
