These panels contain electronic meters displaying electrical parameters. Typically installed at the point of entry or on an exterior wall, a meter. In this video, we explain everything about the Distribution Box (DB Box) — its recommended gauge, ideal size, and how many electrical pipes it can accommodate. more.
