For indoor installations, this space extends from the floor to a height of 1. 8 m (6 ft) above the equipment or to the structural ceiling, whichever is lower. Another example is a 10-foot-high room. This room has a sprinkler system. Electrical panels need to be installed 4′ off the ground with the center grip handle of the highest circuit breaker is no more than 6'7″ high to be NEC compliant. The clearance around the electric panel must be at least 30 inches wide with 3′ of front workspace clearance. The electric panel door. NFPA 70E, Standard for Electrical Safety in the Workplace, provides guidance in determining the severity of potential exposure, planning safe work practices including establishing an electrically safe work condition, arc flash labeling, and selecting personal protective equipment. 26 is the cornerstone for establishing safe Spaces about electrical equipment. The dimension for height of working space for equipment operating at 600 volts (V), nominal, or less to ground and likely to require examination, adjustment, servicing or maintenance while energized shall comply with the 110.
