The answer is no, a standard stud sensor cannot directly detect live electric wires behind the walls. Stud sensors are designed to detect changes in density caused by studs, and live wires do not have significant density differences from the surrounding materials.
Electrical Voltage Detectors:
However, it’s essential to note that while a stud sensor may not detect live wires themselves, there are tools specifically designed to detect electrical voltage. These tools are known as electrical voltage detectors or non-contact voltage testers. They can help you determine whether a wire is live or not.
Non-Contact Voltage Testers:
Non-contact voltage testers are handheld devices that can detect the presence of electrical current without the need for physical contact. They work by detecting the electromagnetic field that surrounds live wires. When the tester is held near an energized wire, it emits an audible or visual indication (such as beeping or flashing lights) to alert the user of the presence of voltage.
Using Both Tools Together:
Although a stud sensor cannot detect live wires, using a stud sensor in combination with a non-contact voltage tester can provide a comprehensive solution for locating both studs and live wires. By first using the stud sensor to identify a stud’s location, you can then use the voltage tester to check if any live wires are present near that area before drilling or making any alterations.
Safety Precautions:
When working with electricity, it’s always crucial to exercise caution and follow safety protocols. If you are uncertain about the presence of live wires, it is recommended that you consult a professional electrician before proceeding with any drilling or hanging activities.While a stud sensor is a valuable tool for locating studs in walls, it cannot directly detect live electric wires. For detecting live wires, you would need to use a non-contact voltage tester specifically designed for that purpose. By understanding the limitations of each tool and using them together, you can ensure both the safety of your electrical system and the successful hanging of objects in your home.
