Final answer:
The statement that the workspace in front of a panelboard must extend its full width if it is wider than 30 inches is true. The NEC mandates that sufficient space must be provided for safety reasons.
Step-by-step explanation:
The statement is true. According to the National Electrical Code (NEC), specifically section 110.26(A)(3), the workspace in front of a panelboard must be of sufficient width, depth, and height to permit safe operations and maintenance. If the panelboard is wider than 30 inches, the workspace should be the width of the equipment or 30 inches, whichever is greater. This ensures that there is enough room for electricians and technicians to perform necessary tasks without being cramped or risking electrical hazards. Additionally, the workspace must also meet certain depth and height requirements; for electrical equipment with a voltage to ground of 600 volts or less, the workspace should not be less than 3 feet wide or 6.5 feet high, and the workspace depth should be in compliance with the clearances outlines in NEC Table 110.26(A)(1).
