Can the main power box of a new house be moved
For this reason, in most jurisdictions, moving the main electrical service panel is not a task permitted for a homeowner to perform. Local regulations almost universally require that this type of work be performed or directly overseen by a licensed electrician. Relocating an electrical panel is a substantial home improvement project that can vastly improve the safety, functionality, and compliance of your electrical system. The panel is the central distribution point where the main electrical service enters the home and is then divided into smaller circuits. We'll talk about the reasons to move a breaker panel, the legal guidelines you need to be aware of, the step-by-step process of moving an electric panel, and how to assess the cost and timeline of the project.
