Shut off the main breaker to cut power to the entire house. Station an assistant at the breaker panel to prevent unauthorized restoration of power during the project.
Return to the open outlet box in the kitchen and push the end of your fish tape into the empty conduit in the bottom of the box. Continue pushing the fish tape until your assistant tells you it has reached the breaker panel.
Hold the end of your 6-3G SER copper cable against the end of the fish tape so the two form a straight line. Wrap electrical tape around the ends to hold the assembly together.
Return to the kitchen and pull the fish tape through the conduit to place the cable properly. Remove the electrical tape to free the cable. Leave 24 inches of cable hanging from each end of the conduit.
Cut through the outer rubber armor of the cable with your razor knife. Remove 6 inches of the armor, being careful not to damage the insulation on any of the individual wires inside the cable.
Strip 1/2 inch of insulation from the end of each hot wire inside the cable. Twist each stripped end into a "U" shape. Hook each hot wire onto its own brass screw on the receptacle. Tighten both brass screws with your screwdriver.
Strip 1/2 inch of insulation from the neutral wire in the cable. Shape the neutral wire into a "U" shape with your needle-nose pliers. Hook the neutral wire onto the silver screw on the receptacle. Tighten the silver screw with your screwdriver.
Find the grounding lug on your receptacle. It's the one screw not attached to a metal plate. Bend the end of your ground wire into a "U" shape and hook it onto the grounding lug. Tighten the lug with your screwdriver. Connect the receptacle to the outlet box in the wall with the retaining screws. Tighten each screw and install the faceplate.
Strip and connect the wires at the breaker panel. Connect the hot wires to the brass screws, the neutral wire to the silver screw and the ground wire to the grounding bar. Clip a 50-amp breaker into the panel. Don't use this breaker for anything other than your stove.
Restore the power at the breaker panel. Slide the probes of your test light into the outlet to test the circuit. Plug your stove into the outlet and test each of its features.
