The generally accepted and code-compliant height for switches is typically 48 inches (4 feet) from the finished floor to the top of the switch box. This standard helps ensure accessibility and consistency across installations. While the National Electrical Code (NEC) doesn't specify a mandatory standard outlet height for most general-use receptacles, established industry best practices and accessibility laws provide clear guidance. The NEC (Article 210. 52) specifies where receptacles must be placed (spacing along walls, required. The commercial electrical code requires switches at 42 to 48 inches and receptacles at 18 inches above finished floor in most applications. This height is an ergonomic choice, aligning well with the average reach.
