Adding a ground to your outlets

Your house has old wiring, and your outlets don't have the third slot for the ground prong. What can you do? How do you go about adding a ground wire or ground connection to your outlets?

First, why have a ground? The ground wire was added for personal protection. Appliances that have the third prong for the ground, have a portion of the equipment, or casing connected to that ground prong. Then if there are any wires inside the appliance that get loose, and make contact with the casing, the current will flow through the ground wire, instead of you. Without the ground connection, you may well be the best or only path to ground, and you can receive a shock.

So, for your protection, it is a good thing to have grounded outlets where ever you use anything that comes with the ground prong.

Older wiring didn't have the ground.. as the years went by, standards changed, and while it is not usually required to upgrade your house, it is still a good idea. As with all wiring, make sure you are only working on dead, de-energized circuits. Check with your local building inspector to determine if any permits are required or inspections.

Well, perhaps the best way, if access allows, new wire can be run that has a ground. At the entrance box (where your fuses or breakers are), the ground wire will attach to the grounding bar, which in many cases is the same as, or connected to, the neutral bar. Then, in your outlets, the ground wire can be attached to the green ground screw of the new grounded receptacles.

Some homes without the ground wire, may be wired with BX or armored cable. This is the cable with the flexible metal casing around the wire. If this is the supply to your outlets, and it runs from your metal boxes all the way to your entrance box (where your fuses are), you are in luck. The outer casing of this wire can serve as the ground. For you to use this as the ground, your entrance box should be connected to ground (it usually is) and the BX cable connected to metal receptacle boxes in your walls. You should test this first be verifying that the voltage between the hot lead and the box is 110 V. The new grounded outlets should be wired from the green ground screw to a screw into the metal receptacle box.

Perhaps one of the cheapest and simplest ways to address this is by using a ground fault interrupter or GFI also known as a GFCI outlet. This is a good choice for many hard to re-wire cases. Instead of running a ground wire, or connecting a ground connection to the outlet, you will rely on the GFI function to provide the personal protection. It is not the same thing, but for most instances it is better. A GFI breaker or outlet will trip when there is not the same amount of current flowing in both electrical lines. So, if there is a loose wire, and some of the current starts to travel into the casing (toward you), it will trip and stop all current flow. Better than just letting it travel to...
