DIY electrical projects: A reader asked Tim Carter, who writes the Ask the Builder column, if they can run electrical wires in their home. Carter points out that while installing and hammering wire and electrical boxes is not physically difficult, it is difficult to safely install code-compliant systems. “You have to understand that if you decide to install electrical wires, you are indeed playing with fire,” he writes. But even with that warning, he says rewiring a home can be done by a novice with research, an electrician’s guidance, and common sense. It offers a compromise: hire an electrician to handle the advanced tasks and choose one that will allow you to do the more novice tasks, such as nailing boxes and running cables between them. Read on to learn more about how Carter would approach this complex project.
