Equipment work space specifications are provided for both a maximum of 1000 volts and a minimum of 1000 volts. Which code section provides the specifications for 1000 volts or less?

Equipment work space specifications are provided for both a maximum of 1000 volts and a minimum of 1000 volts. Which code section provides the specifications for 1000 volts or less?

• A. 110.34
• B. 110.50
• C. 100.22
• D. 120.68

Answer: (A)

In electrical codes, the space around equipment is linked to the voltage of the equipment. For gear rated up to 1,000 volts, the section that specifically sets the required working space and clearances is the one dedicated to that voltage level. That section provides the dimensions and access rules needed for safe operation and maintenance on equipment at or below 1 kV. The other options cover different topics—approach boundaries for live parts, or other unrelated provisions—so they don’t address the standard workspace for 1 kV or less. Hence, the correct code section is the one that targets 1,000 volts or less.
