Want to drill a hole in the wall, but afraid of wires in the wall?

I don't know if you have the habit of punching holes on the wall, punching holes on the wall, and afraid of breaking the wires inside, which is particularly troublesome to repair, and you need to tear down the wall and pull the wire, which is equivalent to the second decoration. In order to avoid similar situations, we need to find a solution. How to avoid the position of the wire when punching?

Look at the wiring diagram
The wiring diagram is generally left after the decoration company, which is of great use at this time. The figure is clearly marked the direction and position of each wire, at this time, we need a ruler to measure, so this method is the most convenient method, the wall hole, to avoid the wire naturally is not difficult.

The wall finder
This method uses scientific technology, is also the most secure method, a bit similar to the metal detector, hold it to scan the wall, if there are wires in the wall, it will alarm. Careful people will also find that if you scan the entire wall, you can find where the wires are going.

Non-contact measuring pen
The above wall detection from the price point of view, a little expensive, the cheapest is more than 200, if the ordinary family use, the cost is a little high, so the non-contact test pen price will be cheaper, the best is only 40 or 50 yuan, if the wall of your home is too thick, don't forget to first play a shallow hole in the wall (remember to plug the pen into the eye test oh)

Estimated by the direction of the slot
Some experienced electricians probably take a look at the surrounding switch socket to know how the wire is probably going, first of all, the wall line is mostly horizontal and vertical, so the switch socket next to the horizontal and vertical direction may have wires, each electrician's wiring habits are different, or depending on the situation.

Remember the rule, there are wires above the switch, it is safer to drill holes below. There's a wire under the socket. It's safe to drill holes above it.
