![]() The cable can then be attached at intervals to the basement’s ceiling joists right up to the electric panel. It does not matter, however, which of the red and black wires goes on which of the hot terminals. 3a & 3b), the hot and neutral lines are all attached to identical slots so that the one opposite the ground semi-circular opening is for the neutral and the other two opposites ones are for the two hot wires. The outlet cover can then be screwed in place onto the box.įor a range receptacle (Fig. The bare copper (ground) wire is fastened to the semi-circle-shaped opening’s terminal and the white Neutral wire to the “L” opening opposite to the ground. Every terminal screw is loosened and the red and the black wires are inserted and secured at the two elongated slots’ terminals. Looking at it from the back (Fig 2b), all of the outlet’s terminals look the same. The box is then pushed into the opening, cable end first, and fastened in place onto the stud. With the three wires and the ground wire exposed, 3/4” (19mm) of insulation must now be removed from all three insulated wires.Ī cable connector is then secured through a knockout plug opening and the cable passed through it and secured, inside the box. With the cable pulled out through the outlet’s opening, about 8” (20cm) of its jacket must be removed using a utility knife. The makeshift fishing gear can be taped up to the cable and pulled through the outlet’s opening. When it reaches the outlet’s opening, a piece of rope, or twine, or soft wire can be attached to it, allowing you to pulling everything back down to the basement, while keeping the other end outside the wall. One approach is to tape the dowel to the cable’s end and push it through from the basement, aiming for holes already made.Īnother method is to insert the dowel alone through the hole(s) from the basement. Since there could be multiple holes to pass through, this may require some imagination, but any way it’s done requires the use of a long, skinny and stiff dowel, rod, wire, or something else of the sort. With that done, if there was an obstruction in the wall above, extension stems are available for deeper reach so the drilling can be completed. From that spot in the basement, measuring 2” (50mm) over and perpendicular to the orientation of the wall will determine where to drill with a spade bit. Inserting a long piece of wire through the hole and leaving it hanging into the basement will give up its location from below. To locate the position where it should be drilled from the basement, drill a small hole through the floor with a 6” (150mm) or longer drill bit, in the corner of the baseboard and the floor. ![]() A hole slightly larger than the size of the cable will need to be drilled from the basement up through the wall plate directly under the outlet’s opening. ![]() With the box opening cut out, the wall can be checked for obstructions. The outline of the box can now be cut out with a keyhole saw or similar tool. The electrical box can then be placed flat on the wall at the stud mark and outlined with a pencil. If you don't know quite where the stud is, you can drill a series of small holes moving toward the stud location until the bit hits it. Step 3 - Cut the Opening for the Electrical Boxĭrill a hole where the box will be placed. The immediate area of the wall should be scanned with a digital multi-scanner as a secondary precaution to detect metal plumbing and electric wires and help prevent accidental damage.Īlways proceed with caution while working inside walls, probing and feeling for any resistance or obstructions from undiscovered items. If there's any chance of damaging plumbing, the water supply should be turned off as well. The nearest stud should be located and marked on the wall at the required height.Īll the circuit breakers feeding the vicinity should be turned off to prevent the risks of electrocution or fire from a short circuit. For this type of installation, complete the safety evaluation in Step 2 and then head straight to Step 7.įor an in-wall installation, the outlet’s location should be chosen carefully to avoid any existing electric wires or plumbing. If the appliance will be placed in front of and hiding the outlet, as is often the case for a clothes dryer, the electrical box can be screwed on the surface of the wall close to the floor, where it will mostly hide the hole.įrom this hole, the wire will snake down to the electrical panel and hook up to the breaker, usually in the basement. Just remember, this kind of project can be dangerous if you don't know what you're doing. If you're interested in learning about the process, though, you might enjoy checking out how it gets done. Installing or adjusting electrical components like these is a job for a professional, and in some places it's illegal to attempt without certification.
