Surface-mounted wiring is achieved when you use hollow channel (often called raceway) to extend the circuit. By simply adding a surface-mounted extention box, add a piece of raceway, and add a box in the new location, you'll have a new outlet in your home in no time at all.
The boxes and raceway are made of PVC plastic and are very durable. The raceway comes standard in 5' lengths. There are inside and outside corners, splice plates and 90 degree corners to form the raceway in whatever direction you need to go. The raceway comes in two pieces that include the back and front cover. There are shallow and deep boxes for all of your different installations. There is also two-gang boxes that will accomodate more than one device. These boxes allow you to extend outlets, switches and also light fixtures. That's right! You can actually tap into a circuit, add a switch, and then feed a light fixture in the middle of you ceiling. I know that some of you have homes without a light in the ceiling, but this can give you one and shed a whole new light n your home!
The downfall of this installation is that is is visible, but with the addition of paint, you can make the raceway and boxes blend into their surroundings. All in all, this makes a quick fix to a problem of too few outlets. Always remember that the crcuit that you connect to can only handle so much load. More outlets doesn't mean more power, just more places to plug in to.
