Electrical Exam Term
Working Space
The clear space required by the NEC around electrical equipment to allow safe operation and maintenance.
Detailed Explanation
NEC 110.26 specifies minimum working space requirements: 36 inches deep (for 120-250V equipment), 30 inches wide (or width of equipment, whichever is greater), and 6.5 feet high. The space must be clear of storage and obstructions. These requirements ensure electricians can safely access panels and equipment for maintenance, testing, and emergency disconnection. Violations are among the most common code inspection findings.
