Remodeling An Old House: Rewiring

Remodeling an old house involves several fields of interest which can be performed easily with some helpful instructions. One of these is the electrical field which requires knowledge on how to install new electrical wiring.

In rewiring a remodeled house you will discover that it is not as difficult as it may seem. With a little common sense, some patience, and a few simple steps, you can do it yourself. You will also save a few bucks.

This project will require a little more effort to do than it would on a newly built house. However, the money you will save and the knowledge and experience you attain will make it well worth your while.

In doing this job and any other job involving electricity, be sure to take all precautionary measures to ensure your safety, including the use of good, protective eye wear.



If the breaker box is in place, make sure the power is turned off before starting this project. Keep in mind that electrical wires will come from the breaker box to feed circuits run. Be sure to check the amperage of all your electrical appliances you will have so you will use the correct size wire to correlate with the amperage of the appliances and to connect the wire to the correct size breaker to accommodate accordingly. Aromex wire of 12-2 guage wire with ground should be appropriate for the outlets, switches, and lights. Be sure to check with your local power company for requirements, guidelines, and restrictions.

Once the number of outlets, switches, and lights per circuit is established, plan out the circuits. If the house is of age, pull the new wire through with the existing wire. Some assistance will be required. Have your helper remain below while you carefully climb up into the attic. Trace the wire coming from the breaker box to one of your designated locations. To avoid cutting holes in the walls, knock above the outlet where the wire descends. You will see where this is when you trace the wire. The wire will go through the hole and down the wall to the outlet or switch. Your helper should be able to pin point the spot. Enter the light with the wire leaving enough wire (no more than seven or eight inches) in the box to work with. Remove only the old wires in the box.

In whatever room you begin, have your helper knock on the ceiling just above the outlet against the wall. You should be able to see where it is and feel the vibration from the knocking below. Have your helper remove the box below while you snip off enough of the old wire to tie on to the new wire. Make sure that the wire going down the wall is loose. One of you can tug on the wire and the other can feel for pull. Strip back the insulation about three to five inches. Cut the black and white wires leaving only the grounds. Loop the grounds with each other and twist snuggly closed. Using electrical tape, wrap from about two inches before the wire is stripped through about two inches before where the other wire is stripped. This keeps the wires from pulling apart. Have your helper pull the wire from underneath while you feed the wire directly into the hole for easy pulling. Strip the wire back, slip it into the breaker box, and replace the box. If you wish, you may go ahead and install the outlets while you are there. Repeat the same procedure according to the number of outlets, making sure to mark or identify the wire going from the right to the switch. Identify on the left. If you make each room a separate circuit, do not be concerned with overloading. To make the connections on the right, strip back all the wires equally. Take all bare wires, which are the grounds, and twist together. Cut off all but one and bend it back. Take a wire cap and twist it on. Push it up in the box and leave the wire hanging. Take the white wire from the switch and connect it with the blacks from all the other wires. Twist them together and twist on the wire cap and push up in the box. Twist all the remaining white wires together. Take a single strand of white wire and twist with whites, but leave it hanging.

You now have a circuit feeding through and a light ready to be hung. Install the switches by stripping the insulation back, exposing the white, black, and ground. Screw the ground on the green screw and the black and white on either one of the two remaining screws, one above the other. Install the light fixture.

At the breaker box enter with enough wire to connect on the breaker. Connect accordingly. Repeat the same procedure for the other rooms. Simply drop the wire for the appliances where they will go. The type of outlets must also be established. Check the amperage to determine the size of wire and the breaker needed. Make sure to tighten all wires on the breaker box and the neutral and ground bars.

Home repairs, interior designing and remodeling usually involve working with electrical wires. If you carefully reviewed and followed each step, your completed project of rewiring an old remodeled home should be a total success.
