How do you not drill into electrical wires?

Electrical wires, for example, tend to follow a certain pattern of placement. “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.

What happens if you drill into electrical wire?

You drill into one conductor, almost severing it but not quite. Everything is fine until the cable is left carrying power near its rated capacity for an extended period, at which point the weak point gets hot. It might melt and cut the power, or if you are unlucky it arcs and sets fire to something.

How do I know where the wires are in my wall?

According to Popular Mechanics, the best tool for locating wires is a stud finder with AC wire detection. Use painters’ tape around the area you wish to scan; this will serve as a place to mark the location of the wires after detection.

Can you hit wires when drilling?

Avoid drilling near light sockets or outlets



One of the main reasons drilling into the wall can be dangerous is that you risk hitting electrical wires or gas and water pipes. … A simple rule of thumb is to avoid drilling anywhere near where there may be electrical hookups or piping.

Can I drill above a plug socket?

Don’t drill directly above or below light switches and plug sockets. Invest in a stud finder/metal detector (as mentioned above) that will detect wires and pipes. If you do mistakenly drill into a water pipe, think of the little boy with his thumb in the dyke and LEAVE THE DRILL BIT IN THERE.

How do stud finders detect wires?

More advanced stud finders called “multi-scanners” are designed to find electrical wires using a small radar that also has metal detecting radars. As your stud finder runs along the wall, if it comes across as stud that has live wiring running through it, the beeping will turn more into a screeching sound.

Will I get electrocuted if I drill into a wire?

Damage to electrical wiring from drilling into walls is a surprisingly frequent phenomenon – especially when buildings are being renovated. In the worst case, if the protective earth conductor has been damaged you otherwise run the risk of a fatal electric shock.

How do most electrical fires start?

Most electrical fires are caused by faulty electrical outlets and old, outdated appliances. Other fires are started by faults in appliance cords, receptacles and switches. … Removing the grounding plug from a cord so it can be used in a two-prong electrical outlet can also cause a fire.

Do electric wires run up or down?

Electrical wires typically run either vertically, up and down the side of a stud or horizontally. The vertical wires are typically pretty easy to avoid: avoid drilling above a receptacle or light switch.

How far behind drywall are wires?

Wires aren’t supposed to be installed any closer than 1-1/4 in. from a penetrable surface (the outside of the drywall). That means you shouldn’t be drilling holes right next to the drywall. But it’s not always easy to control where a flex bit goes.

How far behind wall are wires?

Most cables will be at least an inch deep into the wall, so by avoiding deep drilling, you can be sure to avoid wires.

How do you know you hit a stud?

Make a fist and knock on the wall with your knuckles. In some places, you’ll hear a hollow sound. Other areas will sound more “solid.” The “solid” sound indicates you have knocked on a stud. Studs are located about 16 to 24-inches apart.

Can drilling into a stud cause a fire?

Yes, drilling a hole, and also sawing, can create enough heat from friction to start create smoldering embers in the saw dust generated. It isn’t common but I have seen it occur a few times over fifty years in woodworking shops. Striking metal embeded in wood can also create sparks that can start a fire.

What happens if a nail hits a wire?

It’s common practice to staple electrical cables to the sides of wall studs, and a nail has to be well placed to puncture one, but it happens. If the nail makes contact with the hot conductor, the nail becomes live, and you can be electrocuted by touching it.
