How To Avert Drilling Into a Wire Behind Drywall

If there's ane thing that can be learned past this feel, it'due south that you don't want information technology to happen over again! I experience quite fortunate in that while I accept listened to and hopefully learned from others' horror stories, I've avoided that item mishap and then far. But I tend to be ridiculously cautious.

• Don't push it. In the U.S. it's mutual to find wires passing through holes drilled in ii 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 observe yourself drilling into heavy resistance, stop. Yous may have hit a nail plate covering.
• If the wall you're drilling into was washed correct, vertical wiring should be anchored to the centre of studs. By limiting your nail or screw length to one ane/2 inches or less, you greatly reduce your chances of hitting internal wiring.
• Utilise a wire and/or stud finder. A wire sensor will indicate the path or power sources in your walls. This can be especially helpful in older or highly renovated areas.
