Installing Electrical Wiring
Electrical Question: Can electrical wire testers and wire locators accurately show where electrical wires are inside a wall?
- I wanted to find out if I can safely drill a wall not far from the Main panel in the apartment.
- Drilling would occur on the same level as a panel is, same wall, opposite side, about 2 ft away.
- I have no idea how the conductors are run inside the wall to and from the panel and don’t want to hit one.
- Any suggestions? Should I forget this idea?
- Can the electrical wire locators really accurately determine whether there are conductors in that spot?
Thank you very much in advance.

Electrical Question #2:
- We bought our 1988 house last year and just recently looked into doing some minor improvements to the downstairs bathroom. While pulling off the wallpaper and removing the counter we discovered there was a thick exposed wire protruding from the corner. It looks like maybe they used a wire that wasn’t long enough and dry walled around it as well as cut out a piece of the vanity corner to make a space for it. I’m not sure what to do about it vs. just paint the vanity and get a new top so that I don’t have to deal with the issue. Any advice?

Basic Fundamentals of Home Electrical Wiring
Obtaining knowledge before starting a home electrical wiring project is very wise. The information below will describe how to avoid hitting an electrical wire and causing damage.
Basic Methods of Home Electrical Circuit Wiring
Understanding The Path Of Electrical Cables as they have been installed inside the building structure.
- Home Wiring Techniques
- Electrical circuit wiring is generally run out to the top of a panel or the bottom and often both.
- The Electric Panel
- The electrical panel can be opened by an electrician to visually see which way the cables are headed, however you still don’t know exactly what is happening inside the wall.
- Electric Wiring Inside Walls
- Most walls have outlets and switches so there will be wiring that is looping these devices together running from side to side, and up or down, it all depends on the layout of the dwelling.
- Exposing Electrical Wiring
- To avoid damaging electrical cables one option would be to open the wall up.
- If one is careful the removal of a section of sheet rock can be done relatively easy, especially if you locate the nails or screws and remove them allowing the section of sheet rock to be removed in one piece thereby allowing you to reused the original piece.
- Wiring in Apartments and Rental Homes
- You may want to consult the manager of the apartment complex and get permission before proceeding with your proposed project.
- How To Locate Electric Wires
- There are cable locators that do a fine job, however you must remember that they may only be sensing cables that are energized and may not be locating a cable used for switching a light fixture on.
- If you are drilling a hole simply for the purpose of installing a wall anchor, then just be sure to drill the hole the depth of the sheet rock, or better yet just us a pick to make the hole.
- Sheet rock is relatively soft and easy to penetrate which makes it easy to insert molly bolts or other wall anchors for hanging pictures or other wall decorations.
