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. This article reviews (2) when the electrical equipment is 1000 V or more.
Minimum clearances in front of electrical equipment (600 V (now 10000 V) or more);
