How to Find an Electrical Cable in Your Walls How to Find an Electrical Cable in Your Walls
It's essential that you learn how to find an electrical cable in your walls because many DIY projects involve drilling holes. Accidentally cutting through one of these cables could make your project take much longer in a best case scenario, and in a worst case scenario could actually be deadly. It's essential that you check and are always on the lookout for electrical cables, pipes and any other obstacles in your walls. Being careful will save you a lot of time, and also help to protect your life.
Step 1 - Studying the Wall
Look out for any signs of obvious dangers in the wall. If there are any switches or electrical outlets on the wall then there's a very good chance that there will be wires and cables in the way. It's also worth trying to guess where the pipes will go through the walls so that you can avoid drilling into them.
Step 2 - Safety First
First, you must ensure that the power is switched off before doing any work anywhere in your home. By switching the power off you will be able to take the face plates off safely. It will also mean that even if you drill through a cable you are safe.
Step 3 - Looking at Outlets
If your house was wired up properly then the wires should drop down from the ceiling, and there should not be any connections made horizontally or connected from the floor upwards. However, you can't take this for granted. Use the screwdriver to take the face plates off the outlets and sockets.
When the faceplate has been removed from the front of the outlets and switches you will be able to take a look at the direction of the wire. If the wires run up the wall then you should know roughly where the cables will run. If possible, mark the location of suspected cables on the wall in pencil. Otherwise, just make a mental note.
Step 4 - Detecting Wires
The next step is to use your electric wire detector to find out exactly where the wires run through the walls. Use the wire detector and concentrate on the specific areas where you suspect wires to be.
A wire detector is simply a type of metal detector that is able to detect the presence of metallic objects in your walls. This means that pipes and wires will be discovered by these systems.
Step 5 - Drilling Holes
Once you've marked the rough locations of wires on the walls you should be able to avoid them. When fixing a shelf or anything else onto the wall simply remember not to drill through that specific portion of the wall. This will ensure that your home's electrical systems and plumbing are completely up to scratch.
No matter how careful you are there is always the possibility of making a mistake and drilling through a cable. If you do, the key is not to panic. You might also need to hire a professional to help re-wire your property.
