So, you’re having problems with your home’s electricity distribution and you’re looking to make some changes. Maybe you want more outlets so that you can use and charge your devices from a broader range of locations. Or maybe you want better lighting. Or maybe you’re looking to update your house before selling it.
In any case, knowing how to fix your home’s electrical wiring will provide you with a valuable foundational understanding of how to fix electrical problems as they occur. You probably, however, save time or save money in the process of doing this electrical work yourself, unless you have experience or already own many of the necessary parts.
If either this job is extremely important or you don’t have a lot of patience, then it’s highly recommended that you hire out the work to a licensed contractor. All electric works needs to satisfy your city’s electric code and, if you don’t own the house and property, then the building administration might require only licensed electricians to perform work on the building. Thus, depending on the circumstances, doing this project yourself could either be illegal or require multiple attempts and re-wirings in order to meet the appropriate code.
You can save a lot of money by doing your own wiring. Here we’ll show you to wire an entire room. Even if you’ve never picked up an electrical tool in your life, you can safely rough-in wiring by following the directions in this article. You’ll learn all of the pro techniques for a wiring job, including choosing the right size receptacle boxes, running cable throughout the room, and making the electrical connections.
Although the process illustrated step-by-step here is quite simple, the timing for the task is difficult because in order to install anything new or replace anything outdated, you’ll need to strip the wall. Accordingly, the best occasions to perform this kind of electrical repair are when you’re remodeling any particular room, adding or subtracting walls to your house, or selling/moving into your home.
Before beginning any electrical repair, shut off the power. Remove the fuse or trip the breaker for the circuit you will be working on in your service panel. Use a neon tester to be sure the power is off. If there is any doubt, you can remove the main fuse or trip the main breaker. Remember: Removing the main fuse or tripping the main breaker will usually shut off the power to the entire house.
Electrical wires are color coded to prevent wiring errors. White wires almost always connect to other white wires or to chrome terminal screws on switches and receptacles. Some wiring devices–such as receptacles–are back-wired by pushing the bare wire end into spring grip holes. These wiring devices are plainly labeled to show which color goes into each spring grip hole. Switches are nearly always connected into black wires in cables. The only exception is where a cable is extended, making it necessary for the white wire to play the role of the black wire. When this is necessary, the white wires should be painted black to prevent future wiring errors. Study the wiring diagram. This will help you understand the basic principles of good wiring. Also, find a good electrical how-to book. It’s one book every homeowner should keep on hand for ready reference. Most home wiring is complete with either No. 14 gauge or No. 12 gauge wiring. No. 14 is the smallest wiring permitted under most codes. Always use the same size cable for a continuation of any extended wiring circuit. Read More Here
