Keep the 3 wire circuit to the main box and add a separate wire to a ground point like a water pipe. Ground wires for individual branch circuits or metal sheathing that acts as a ground lead back to the neutral or ground bus bar of the service panel.
Fundamentals Of Electricity
Where does the ground wire go. The service panel itself must be connected to the earth so that the entire electrical system is safely grounded. Thats not quite as simple as it sounds tying the ground wire to a ground electrode driven into the earth is not generally sufficient to trip the breaker which was surprising to me. Typically the ground wire is attached to the metal housing of the light fixture. In order to do this you will begin by finding the ground screw that is going to be found either on the mounting bracket or on the actual light fixture. The second method is to have a wire from the negative side of the part go to a switched grounding device like the on board computer or ecm. National electric code article 250 requires that the ground wires be tied back to the electrical neutral at the service panel.
This may not be allowed under some local codes sounds like option 3 was what your husband did. The ground wire connection should provide a continuous bond throughout the metal components of the light fixture. Normally the current returns to ground through the neutral wires in the electrical system. Originally the term applied only to wires that were actually connected to the earth and in many cases this is still true. If the wire is covered with green insulation you will need to strip 12 inch of the green insulation off of the tip of the wire. But should some breakdown of the pathway occur the hot current may instead flow through other materials such as wood framing metal pipes or flammable materials in your home.
The first method is a common ground that connects several grounds to one wire that then goes to a good location on the frame or to the engine. A ground wire sometimes also referred to as a grounded wire is an electrical wire that neutralizes and protects devices appliances and buildings from current problems and shocks. So in a line to case fault the fault current flows through the appliance ground wire to the service panel where it joins the neutral path flowing through the main neutral. Locate the ground wire coming from your homes electrical box where the light fixture is to be installed. In some cases the ground wire extends through out the light fixture to junction box locations where the light socket wiring is spliced together. Get needle nose pliers and twist the very tip of the wire to make a hook.
The ground wire will be either green or bare copper wire. Once you have found it you will take the ground wire that will be coming from the electrical box in your home.
