Learn how to install a central vacuum system with outlets on four floors and hidden PVC piping.
Thread the cable through the hole provided in the outlet back plate and connect it to the outlet cover. To connect it, first separate the insulated sheathing between the two wires for an inch or two and then use a wire stripper to remove 1/2 inch of the insulation to expose the stranded copper wire beneath. Twist the bare wire and loop it over one of the two screws on the back of the outlet plate that serve as terminals/contacts. Tighten the screws to secure the wires. Repeat this step for the other wire and attach it to the other terminal screw.
