The main service panel is typically located in a home's basement or utility room. Some homes also have a subpanel—a smaller version of the main panel—to control electrical circuits in a garage, workshop, or other outbuilding. The National Electrical Code (NEC) does not specify a minimum height for an electrical panel, although practical access for service should always be considered. But there is a maximum height allowed for an electrical panel, which is based on the height of the highest breaker switch in the panel. NEC Article 408 covers switchboards, switchgear, and Panelboards installation and applications. Guidelines set by the National Electrical Code (NEC) provide a framework that ensures these installations adhere to stringent safety protocols. This article provides an exhaustive examination of the principles and standards governing the height at which electrical panels should be installed. The National Electric Code (NEC) includes the minimum standards for installing a circuit breaker panel box. These standards set the minimum safety standards for panel boxes. Tomorrow I'll be looking at a panel that was installed in a dining room knee wall 18" above floor. You can find electric panels inside cabinets, behind refrigerators, or inside clothes closets in older homes. Electrical panels.
