Distance from the front of the lighting distribution box
The working space must extend at least 36 inches deep, measured outward from the front of the panel. That 36-inch figure applies to equipment rated up to 150 volts to ground under the simplest installation conditions. The NEC, published by the National Fire Protection Association, is the baseline safety standard for electrical installations across all 50 states, though local jurisdictions often adopt it with modifications. 1 As of early 2026, 25 states enforce the 2023 edition while 20 others still operate under. Working space: The front clearance, side clearance, and height clearance requirements for electrical equipment that provide a safe area for maintenance, inspections, and other work. Dedicated space: The space equal to the width and depth of electrical equipment in addition to the space extending. These requirements vary depending on whether the electrical equipment is rated at (1) 1,000 volts or less (See, Article #2) or (2) over 1,000 volts. For instance, OSHA's Table R-6 specifies minimum approach distances for various voltage ranges, ensuring workers adhere to safe practices when operating near live electrical parts.
