Height clearance: The minimum headroom in front of the equipment is 6½ feet, or the height of the equipment itself, whichever is greater. At no point can this be less than the height of the equipment.
For installations built on or after August 13, 2007, 1.98 m (6.5 ft), except that where the electrical equipment exceeds 1.98 m (6.5 ft) in height, the minimum headroom may not be less than the height
The height of the working space must be clear and extend from the grade, floor, or platform to a height of 6½ ft or the height of the equipment, whichever is greater [110. 26 (A) (3)].
Minimum clearances are established for work spaces in front of high voltage - electrical equipment such as switchboards, control panels, switches, circuit breakers, switchgear and motor controllers. These
