The difference between the Inside Wireman and the Residential Wireman is that, while the Inside Wireman is performing electrical work in commercial and industrial facilities, the Residential Wireman is performing and maintaining the electrical systems in homes and other types of residential installations.

As technology continues to grow, and houses place more and more demand on their electrical systems, the tasks associated with the Residential Wireman have also grown and evolved. Today's homes are now being equipped with computer networks, energy management systems, security systems, fire alarm systems as well as the standard power distribution systems to lights and receptacles throughout the home. The Residential Wireman installs all of these various systems. These craftspersons are learning the background knowledge and the skills necessary to make these systems work for today's homeowner.
