Electrical Outlets 101: How to Wire an Outlet How to wire an outlet: 4 Steps Step 1: Find out how much insulation to strip from the wire I often notice inconsistencies in how much insulation people strip from the wire before they connect to the screw terminals. Wire the New Electrical Outlet. Mount the new box in the opening. Connect the new wires to the new outlet: white (neutral) wire to a silver-colored terminal screw;black (hot) wire to a gold-colored terminal screw;bare wire to the green grounding screw.Make sure the cable sheath remains secured inside the box. It's important to understand circuit wiring for receptacles before you begin.Household outlet receptacles can be wired in one of two ways,depending on where the outlet falls along the circuit.When an outlet falls in the middle of the circuit run, there will be two cables (or occasionally three) entering the electrical box.One cable is bringing power into the box from the power source,while the other cable (or cables) are carrying power onward to other outlets or fixtures.
