The working clearance between live parts for a system operating at 480 volts with exposed live parts on one side and no live or grounded parts on the other side of the working space must be a minimum of?

Explanation:
The working space around energized parts must provide enough room to maneuver tools and avoid accidental contact. For a system operating at 480 volts with exposed live parts on one side and no live or grounded parts on the other side, the minimum clearance is 3 feet. This distance gives a safe buffer to work without reaching into the live area, balancing accessibility with safety. Larger distances are required only when there are live parts on both sides or when higher voltages or stricter conditions apply, which isn’t the case here.
