As electricians, protecting wiring from physical damage is essential when making a proper installation. When wiring is ran through a buildings foundation or exterior walls it must be protected from moisture and materials that can be corrosive to the wires jacket. We often see the process of physical protection neglected by unqualified electricians creating a hazardous condition and eventually wiring failure. Service entrance cables in front of home or business where the public has direct access must be protected with EMT or PVC schedule 80 pipe. The cable must also be protected where it enters a home or business. The image above shows what happens when a service entrance cable is not properly protected. Romex is the common name for nonmetallic cable used primarily in homes. Romex is to be installed in dry locations only. The image below shows Romex exposed on the outside of a home, a code violation. This same wire was not protected through the exterior wall and the result was failure of the wire which created an unsafe condition.
