What happens if you drill a hole in a power cable?
Your first warning would be the thing that the wire is carrying electricity to suddenly losing power, but of course that would be contingent on that thing being powered on at the time you drilled through the wire.

What happens if you nail into a live wire?
It could get hot enough to ignite a fire on the wrong side of the walls. Of if the wire is cut entirely, or passing through the nail, it is bound to start arcing. Arcing makes a tremendous amount of heat - it will heat up much, much faster than a nicked wire, and could start a fire going in less than a minute.
How deep are electrical wires in walls?
How far into the wall are wires located? Wiring usually runs horizontally, about an inch into the wall. The parameters are 6 inches or 12 inches above the receptacle.
Do electric wires run up or down?
Horizontally from any switch or socket – The zone runs horizontally from both sides of the socket or switch until it reaches a corner or an obstacle such as a door. Vertically from any switch or socket – the safety zone runs the width of the socket or switch both up to the ceiling and down to the floor.
How do I know if there are wires behind a 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 a nicked wire cause a fire?
If the nick is deep enough, the wire will overheat at the nicked point. This overheating is not detected by the fuse or circuit breaker and the result is an electrical fire.
How do you avoid cables when drilling?
2 – Avoiding wires 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.

And when you begin your repairs, you’ll want to trip or even completely disengage affected wires from the breaker. For your own safety, don’t ever attempt to repair an electrical wire while there’s still power available to it.

Can you drill through 2x4 studs?
In the U.S. it’s common to find wires passing through holes drilled in 2 x 4 studs. Codes require a protective metal plate to cover the side of the stud to prevent drilling into the wires. So if you find yourself drilling into heavy resistance, stop. You may have hit a nail plate covering.
