Running electrical conduit on the surface of a wall is an easy way to add wiring to a workshop, garage or basement or anywhere else there are no open stud cavities. And electrical metallic tubing (EMT) is a perfect choice. It's strong, cheap and easy to bend once you learn how. After the conduit and boxes are mounted, you push or pull wires into them, and connect the wires to the switches, outlets, lights or other devices you're installing. These tips will help you get the job done right.
