How to Fish Wire Through a Wall: Step-by-Step Guide for Beginners

Gather Materials

Gathering Materials

Before you start fishing wire through a wall, it is vital to collect all the necessary materials. These materials include fish tape, hand drill, drill bits, fish rods, wire, and fish tape. Each tool plays an essential role in accomplishing the task at hand.

The fish tape, also known as the draw tape, has a long semi-flexible steel wire and is available in several lengths. For those hard-to-reach places, this tool is helpful as it can go through several bends even in tight spaces.

The hand drill is useful when you need a hole in a wall or ceiling, allowing you to pass the wire through. A drill bit comes with various sizes and is suitable for different materials such as wood, metal, or concrete walls.

The fish rods come in varying lengths because they solve the problem of a lack of access when drilling through a ceiling or wall. They help reach the wall cavity without any fuss.

Lastly, you need to acquire electrical wires, which come in various grades depending on its use and durability. Therefore, it’s wise to take this factor into account while choosing wires.

Locate Studs and Obstructions

Before fishing a wire through a wall, it is crucial to locate the studs and any other potential obstructions. Studs are vertical wooden beams that make up the framework of your wall. Most walls have a stud every 16 inches. Obstructions can include electrical wires, plumbing pipes, and ductwork. Knowing the location of these obstructions will help you avoid damaging anything when fishing the wire.

The easiest way to locate studs and obstructions is to use a stud finder. These handheld devices use sensors to detect changes in the density of the wall. When it detects a stud or obstruction, the device will beep or light up.

When using a stud finder, start at an electrical outlet or light switch in the room. This is because these fixtures are typically attached directly to a wall stud. Move the stud finder horizontally across the wall until it beeps or lights up, indicating the location of a stud. Mark the location with a pencil. Repeat this process until you have marked the location of all the studs in the wall.

Once you have located the studs, you will also want to locate any obstructions. Obstructions can be located using the same process as locating studs. Use the stud finder and mark the location of any obstructions you find on the wall.

If you are unable to locate studs or obstructions using a stud finder, you may need to try a different method. One option is to use a flashlight to look for nails or screws in the wall that indicate the location of studs. Another option is to knock on the wall and listen for a solid sound, which indicates the location of a stud. However, both of these methods are more time-consuming and less reliable than using a stud finder.

Make a Small Hole

If you want to install a new electrical outlet or light fixture, or need to mount a TV on the wall, you may need to fish a wire through the wall. Drilling a small hole in the wall is the first step to route a wire through the wall. Before drilling a hole, make sure you know what’s inside the wall, such as electrical wires, pipes, or studs. You can use a stud finder or a hole saw with a built-in wire detector to locate potential obstacles before drilling.

To drill a small hole through drywall or plaster, use a power drill with a small drill bit, such as a 3/8-inch or 1/2-inch bit. Hold the drill perpendicular to the wall and apply gentle pressure to start drilling. Keep the drill steady and apply constant pressure until the bit penetrates the wall. Avoid tilting or angling the drill, as it may cause the bit to break or damage the wall.

If you are drilling through a brick or concrete wall, you will need a masonry bit and a hammer drill. Make sure to wear safety goggles and a dust mask, as the drilling process may generate dust and debris. Mark the spot where you want to drill with a pencil, and then insert the masonry bit into the chuck of the hammer drill. Turn on the drill and apply firm pressure to the wall while keeping the bit perpendicular to the surface. Once you have drilled a hole, insert a wire coat hanger or a fish tape through the hole to get a sense of the interior wall cavity.

Connect Wire to Terminals

Connect Wire to Terminals

After successfully fishing the wire through the wall, you’re now almost finished installing electricity to that area. Now, it’s time to connect the wires. The process may seem intimidating, but rest assured, it is not difficult. You only need to follow these simple steps to get the job done with ease.

Step 1: Strip the insulation off the wires. With a wire stripper, remove about ¾ inch from the end of each wire. Twist the exposed wire into a tight bundle to make sure no stray copper strands are sticking out.

Step 2: Look at the outlet or switch you will be wiring and determine which color-coded screws are the terminals for the colored wires you are connecting. Keep in mind that traditional electricians typically use black for hot, white for neutral and green or bare for ground wire. It is essential to note which screw is for which wire to ensure the proper connection.

Step 3: Position the wires by placing them under the appropriate screws and tighten each one firmly with a screwdriver. Make sure that the wire is curved clockwise around the screw, so it will be tightly wound when the screw is tightened, preventing twisting or kinking. Keep in mind to connect the black (hot) wire to the brass screw, the white (neutral) wire to the silver screw, and the green (ground) wire to the green screw.

Step 4: To ensure the wires stay connected and in place, it’s best to have a reliable electrical tape. Wrap the tape around the connections but make sure it’s not too tight that it will damage the insulation of the wires.

Step 5: After connecting the wires, carefully push them back into the box without getting snagged on other electrical components inside the box. Avoid forcing the wire too tight so that it won’t get damaged or become loose. Use two screws or brackets to hold the outlet or switch in place, which will help avoid any bending or warping that can loosen wires.

Step 6: Finally, turn the power back on and test the outlet or switch to ensure it’s safely powered. With a simple process of flipping the switch or plugging in an appliance, you can check if your electrical work was successful or not.

Remember that safety should always come first when it comes to electrical work, so before you start fiddling with any wires or screws, ensure the power to the area is off. Label the on and off switch to avoid having anyone turn the power on while you’re working. Call an electrician if the process seems too complicated or if it’s your first time working with electrical wiring. If everything checks out after your installation, congratulations, you did an excellent job!

Test the Connection
