Circuits and Wiring
The circuits and wiring in your home or office are vital to delivering electricity effectively and efficiently throughout the building. Turning on a light switch. Plugging in a toaster. Pressing the power button on the TV or the computer. These activities are something you do every day and probably take for granted. Circuits and Wiring are essential to do these activities and a professional electrician will help make sure it is done right.
All these tasks need electricity and the wiring in your home carries this electricity to each and every room. Electricity comes into your home from the power company and is then distributed throughout your home through electrical circuits and wiring.
Wiring and circuits are integrally important to delivering electricity throughout your home. In the United States, electricity is delivered and consumed using 2 main voltage specifications, namely 120 volts and 240 volts.

When it comes to the actual wiring in your home, the most common type of wiring is what is referred to as NM or nonmetallic cable. This cable consists of two or more individual wires wrapped inside a protective plastic sheathing. NM cable usually contains one or more hot wires, a neutral wire, and a ground wire.
You may need electricity in areas of your home that are exposed to water. For this type of application, an electrician will use Underground Feeder or UF cable. UF cable is a type of nonmetallic cable designed for wet locations and can be buried directly in the ground. It is commonly used for supplying electricity to outdoor fixtures, lampposts, and outdoor lighting.
Always make sure anytime you are working with the electrical circuits and wiring in your home that you consult a licensed professional electrician.
