Exterior lamps outside your home, including the porch lights and entrance lights, are installed in the same way as the interior lights, and are part of the same house circuit. The main difference is that the exterior lights are designed to withstand weather conditions, so it is important to make sure that the accessory that is installing is made for outdoor use. Normally, cable connections are made with wire covers only, but for outdoor accessories, it is a good idea to wrap them in electrical tape, thus providing additional protection against moisture.
Ideas for mount the exterior lamps, switch off the existing external light in the fuse box. Use the screwdriver to remove the screws that hold the existing lamp in place. Disconnect the cables behind him. Look for the mounting bracket for the new light, which is a flat metal plate with holes in it. Hold the support to the electrical box. Align the screw holes and insert the screws that come with the bracket, to secure it.
Fix the bare copper ground wire to the green ground screw on the mounting bracket. And then adjust the screw. Hold the light to the electrical box and connect the white light wire to the white wire of the box. Turn a plastic cover over the two cables to connect them. Wrap the connection with electrical tape.
