An electrical panel is the single most consequential piece of equipment in any building. Every circuit, every outlet, every appliance, and every life-safety device traces back to it. When the panel is correctly sized, properly grounded, and made by a manufacturer that didn't have product recalls, the building's electrical system runs invisibly for decades. When the panel is undersized, deteriorating, or one of the brands flagged for fire risk, every other electrical decision in the home is constrained by it.
