Using an Electrical Circuit Tracer Follow the manufacturer's instructions for using the electrical circuit tracer, and move the receiver along the wall surface to follow the path of the wires. The tracer will emit an audible or visual signal when it detects the wire, helping you identify its location accurately.
LinesearchbeforeUdig is an online service that helps you identify the location of underground utility assets before you start any digging or excavation work. This helps prevent damage to electricity, gas, water, and telecommunications networks.
Investing in professional equipment, such as a cable avoidance tool, is the safest option to avoid wires. However, if you don't have access to this, most wiring runs horizontally 6 inches or 12 inches above the receptacle, so avoid these areas. If it is possible, only drill shallow holes.

Using a Stud Finder
The stud finder will indicate the presence of wiring by detecting changes in density. When the stud finder detects a possible wire, mark the location on the wall and move the tool horizontally and vertically to trace the wire's path.
For a fully comprehensive model, the Bosch GMS120 Digital Multi-Scanner is one of our favorites. It is extremely accurate and has modes to detect wood, metal, and electrical wiring behind the drywall, as well as specialty features like a center finder and magnetic sensor.
Using a stud finder is much safer to trace wires, especially high-voltage ones. You won't need to unclip or unwrap the wires. Hover the stud finder over the wall. It will generate images or tones to show the wiring.
The cost of an electrical inspection is greatly influenced by the specific type of inspection required. For a basic electrical system inspection, you can expect to pay between $110 and $175. If your needs extend to specialized inspections like code compliance verifications, these range from free to around $100.
When they check the wiring in your house, electricians will look for signs of fraying or damage. Such signs include exposed wire dangling from ceilings or coming out of the wall, wires that pop out of the protective coating, or cracking in the insulation caused by brittleness.
“One common rule is to avoid drilling around light switches and sockets, as the electrical wires can go horizontally and vertically around these fixtures,” Williams explains. “You can also get an idea of where wires and pipes run by looking in the attic and basement to see where they go up or down through framing.”
Per the 2018 International Residential Code, electrical wires should be set back no less than 1-1/4 inches from the edge of the framing lumber. Limiting drilling depth to less than 1-1/4 inches is a good start to reducing the risk of damaging wiring behind the drywall.
Not only do the lights go out, but you usually blow a fuse as well. With a bit of luck, you might only have to repair the cable sheath. But if you damaged or severed a wire, just using a terminal strip, insulation tape and some silicone sealant are not recommended – you need some professional kit!
Use your detection tool to scan the wall or ceiling thoroughly and mark the safe drilling spots with a pencil. Know the warning signs: Electrical wires usually run along the sides of studs and often vertically from outlets or horizontally at the same height as outlets.
Always find the location of a utility line by having the local 811 service visit your property and mark for utilities. Never try to locate a utility line by probing the ground.
The Light Bulb Method
Preparation: For this, you need a socket, a working light bulb, and the wire you wish to test. Procedure: Attach the wire to the socket's terminals. Screw in the light bulb. If the bulb illuminates when the power is on, then the wire is hot.
Your homeowners insurance policy may cover damaged wiring under your dwelling coverage. This may include things like your electrical panel. However, many insurers won't cover certain wiring issues, such as faulty workmanship or repair.
Average Hourly Rates
Typically, electricians charge between $50 and $100 per hour. But the first hour might cost more, about $150, due to initial setup and travel. In emergencies, expect to double the rate to $100–$200 per hour.
If you're worried about your payment, you can contact the sending bank and request a trace on the wire transfer using the reference number¹. Many banks will do this, though you may have to pay an additional fee.
Electricians use a wire tracer to locate wires and identify circuits and breakers without having to put unnecessary holes in walls or waste time guessing to find the correct wire in a bundle or run. A wire tracer has two parts: a transmitter, which generates a signal and sends it along the wire.
The first step in finding a short circuit is to look for physical signs. This may include visible burns or melted metal on wires, burning smells, or flickering lights. Once you've identified a potential short, use your multimeter to confirm the voltage by placing it on its resistance or continuity setting.
A wire detector can be a good supplement to a stud detector when you want to confirm the presence of live wires in an area. A basic wire detector consists of a transmitter and receiver. Certain models will also help you identify plumbing within the walls to avoid a catastrophic leak.
They are usually placed 16 inches apart on all walls. It can vary in older homes, but rarely would you find studs more than 24 inches apart. Windows and doors are also framed by studs for support. Above wide windows and doors, you might even find a wide header board.
