Tracing wires/ DIY....or hire a professional!

DIY works for many...but electrical issues often require a professional. When in doubt, consult with an electrician.....the consequences in guess work can COST more exponentially...

Tracing Wires

­If you need to find the wires inside your walls, you'll probably want a non-invasive way to look for them. After all, without a method to your madness, you'd just be hammering unsightly holes through your drywall in a vain attempt to cross paths with your wires. Instead, there's a better way: With the right tools and techniques, you can locate, or trace, your wiring without damaging your walls.
Tracing electrical wiring in walls can be tricky, and it involves more than just looking for the wires themselves. To figure out exactly where the wires are, you'll look f­or the outlets and appliances that each wire connects to. You'll also figure out which circuit breaker applies to which section of your home's wiring.

­You may be wondering why someone would go through all that trouble just to figure out the locations of wires. Knowing where your wires are can help you make repairs, plan for home improvement projects and even make your home safer. By knowing which outlets are on which circuits, you can decide where to plug in power-hungry appliances without overloading your electrical system. If one of your outlets is on the fritz and you don't have an electrical blueprint of your home to use as a reference, tracing the wiring can help you figure out exactly where the problem is. If you want to run new wires to a home theater system or other electronics, knowing your current wires' locations can help cut down on electrical interference, which can lower the quality of your picture and sound. And you'll definitely need to know where the wires are if you plan to do any renovation or demolition projects to your inside walls. Breaking into a live wire could damage your home and cause serious injury.

Best Practices for Tracing Electrical Wiring

­All-in-one wire tracers come with instructions that allow you to trace the wiring in your walls. You can also use stud-finders with wire-sensing modes to track down specific wires. But you can also get a good idea of where your wires are without such sophisticated devices. There's no one right way to do it. The method you choose simply depends on what your purpose is for tracing wires and what works best for you.
You can find out which wires are connected to which circuit breaker without any tools at all. If you have any kind of electrical wiring blueprint for the building you're testing, this is a decent method to use. If you already know where the wires run behind the walls, testing the circuit breakers simply verifies that the wires and switches are connected. Work with a partner -- one of you should stay at the breaker box to flip the switch, and the other should observe which outlets get power. You can do this without a partner as well, although running back and forth between outlets and breakers is time- and labor-intensive.
Start with all the breakers off, and plug a lamp -- turned on -- into an outlet. Flip breakers on and off one at a time until the lamp lights up. Then, plug the lamp into the other nearby outlets to determine which ones are on the same circuit. Flip light switches to see which circuit the lights are on. Circuits that run to large appliances, like clothes dryers, often have no other outlets or appliances on the circuit.
Another practice of finding electrical wires behind walls is to use a metal detector. This can be an efficient method if you know there are very few wires and if there aren't many other metal objects, like nails, in the walls.
If you're tracing electrical wiring so you can add new outlets or lighting, or if you're getting ready to make electrical repairs, you'll need your voltage detector and other tools for safety reasons
