In this video, you will learn how to make an electrical conduit, mounted on a wall or embedded.
Installing an electrical conduit makes it possible to supply an electrical circuit or appliance. Choosing the right housing and tubing in function of the environment will protect people, goods and electrical cables.
For your safety, remember to wear safety goggles and gloves.
Before this electrical intervention, please turn off the power for the network concerned.
To make an electrical conduit you will need a circular saw, a screw driver, a putty knife, a spirit level, a cutter, a pencil, a length of wood, a voltmeter, a humidity detector, some talcum powder, screws, plastic conduit or trunking, a conductor, a flexible sheath hose, and some plaster.
This operation is carried out in 5 steps, which we will detail for you.
STEP 1: CHOOSE THE RIGHT SHEATH AND CORRESPONDING TROUGH
For a visible residential system, choose a rigid tube or trunking.
For an embedded residential system, choose a cable that you will place in a cut groove, or between partition walls.
STEP 2: PREPARE THE SPACE FOR THE TRUNKING
Mark the shortest possible path to join the two points that need to be connected.
Outline the point where the conductors will go.
Favour straight lines whenever possible.
STEP 3: CUT OUT THE TROUGH IN THE WALL
This step is applicable for embedded conduits.
Tip: Before drilling into a wall, make sure there is no risk of damaging an embedded water or electrical conduit. To do so, use a voltmeter and a humidity detector.
Cut the trough using the grinder.
Cut a groove that is wider than the cable diameter.
Please note: Do not cut a trough into loadbearing walls.
When cutting the trough, do not cut deeper than 30% of the wall’s thickness or you will weaken the wall!
Measure the sheath.
Cut the sheath in function of the necessary length.
Prepare the walls for the casing for any embedded switches and outlets.
Place the conductor in the sheath.
Please note: To avoid crushing or overheating conductors, leave some extra space in the sheath.
Then put the ensemble into the trough.
Slide the sheath into the holes for the casing until the sheath appears.
Fill in the trough with plaster so it is flush to the wall.
Tip: you can reuse the pieces of the wall that you cut out to fill in the trough and replaster.
Let the plaster dry for 2 days.
STEP 4: ATTACHING THE ELECTRICAL TRUNKING
This step only applies to conduits that are mounted on walls.
Open the trunking. Place it against the wall. Note the site for the attachments.
Attach the trunking using screws.
The connections between trunkings are at 45 degree angles where the angles change.
Insert the conductor into the trough. Close the cover of the trough.
STEP 5: CONNECT ANY OUTLETS OR SWITCHES
Before turning on the power, connect any outlets or switches.
To do so, please watch the videos "How to connect a switch" or "How to connect an outlet".
You now know how to make an electrical conduit.
