How To Find Electrical Wires In Concrete Walls

Use a remote return path to find wires in impenetrable walls.

How to find electrical wires in concrete walls.

Use the wire detector and concentrate on the specific areas where you suspect wires to be. To figure out exactly where the wires are you ll look f or the outlets and appliances that each wire connects to. Tracing electrical wiring in walls can be tricky and it involves more than just looking for the wires themselves. Turn the electronic stud wire finder on and slowly move it left and right until the detector beeps indicating it has found an electrical wire.

Start in an area on the wall that is close to a switch or outlet move the detector up the wall and mark the wall to form a trace line of where the electrical wire is located as the detector beeps. Turn the ac power inside your house off connect one end of the bell wire to the starting point in your investigation. Next a remote lead with a longer wire into the transmitter and plug this lead into a separate wall socket. It s output is a logic level.

A fairly simple way to trace the path of a wire is to buy a 75 or 100 foot spool of single strand flexible not solid bell wire. You could even power the push the start button circuit from the wall wart this circuit is perfect in detecting the electrical wires before boring on it. The other option is to carefully plan where the wires would be logically running behind the walls so you know where not to drill. The safest and most accurate way to avoid wires is to use a cable avoidance tool although this would be quite an investment to make if you weren t going to use it regularly.

The transformer in the wall wart takes care of the ac power isolation. This means that pipes and wires will be discovered by these systems. 5v when ac is on 0v when ac is off. Use your transmitter to plug a single prong or lead into an electrical socket of the wall you re tracing.

Step 5 drill holes. You ll also figure out which circuit breaker applies to which section of your home s wiring.
