In this video, you will learn how to connect a ground connection to an electrical panel.
The ground connection makes it possible to dispose of fault currents, in other words when metallic masses accidentally become live.
Before this electrical intervention, please turn off the power for the network concerned.
To connect the ground connection, you will need a tape measure, a level, a pencil, a hammer, a set of electrician’s screwdrivers, a drill, a metal saw and a miter box, a cable stripper, a rigid tube, a main ground terminal, 16mm2 ground conductors, 4 screws and 4 screw plugs, and mounting brackets
This operation is carried out in 3 steps, as we will explain.
This operation is done after installing the ground wire. To learn more, please watch the video “How to install a ground rod”.
STEP 1: INSTALL THE MAIN GROUND TERMINAL AND THE TUBE
Take the cover off the electrical panel.
Measure and mark the middle of the width of the panel with the pencil.
Place the tube in a vertical position starting at this point.
Note and mark in pencil the position of the tube.
Note and mark with the pencil the position of the mounting brackets, above and below the tube, at most every 80cm or (30inches)
Opposite the disconnecting strip and under the electrical panel, note the location of the main ground terminal.
Drill four holes. Insert the screw anchors, using a hammer if necessary.
Screw in the mounting brackets.
Attach the main ground terminal to the wall by screwing it in.
Measure the rigid tube between the main ground terminal and the electrical panel.
Cut the tube to size and then attach it using the mounting brackets.
STEP 2: CONNECT THE DISCONNECTING STRIP TO THE MAIN GROUND TERMINAL
Under the disconnecting strip, drill a hole for the ground conductor to go through.
This will enable the ground conductor to connect the disconnecting strip to the exterior, as installed in step 1.
Insert this conductor into the hole.
Strip the end of the wire.
Connect the conductor to the main ground terminal. Insert the electrical wire into the terminals and then screw them in.
STEP 3: CONNECT THE ELECTRICAL PANEL
Put the main protection conductor into the tube.
Strip both ends of the conductor.
Connect the main ground terminal. Insert the wire into one of the terminals and screw it in.
To connect the green ground strip at the bottom of the panel, insert the stripped ground wire into the terminal and screw it in.
Cut a space out of the bottom of the panel to allow the ground conductor to pass through.
Put the cover of the electrical panel back on.
For the rest of this installation, please watch the video “How to install a ground connection, part 3: equipotential bonding ".
You now know how to connect the ground connection to the electrical panel.
