The dedicated equipment space above a panelboard extends from the top of the equipment to what height?
a.To the structural ceiling in all cases
b.3 feet above the equipment in all cases
c.6 feet above the equipment or to the structural ceiling, whichever is lower
d.6 and 1/2 feet above the finished floor
Explicación
The dedicated space is the footprint of the equipment extended from the floor to a height of 6 feet above it or to the structural ceiling, whichever is lower, and no foreign piping, ducts or equipment may be installed in it. Suspended ceilings with removable panels are not considered structural ceilings, and the 6 and 1/2-foot dimension is the minimum headroom of working space, a separate requirement.
