10.2 – Shock Boundaries
SHOCK BOUNDARIES
The shock protection boundaries identified as limited and restricted approach boundaries shall be applicable where approaching personnel are exposed to energized electrical conductors or circuit parts.
See Table 1A for the distances associated with various ac system voltages. See Table 1B for the distances associated with various dc system voltages.
Limited Approach Boundary (Shock)
an approach limit at a distance from an exposed energized electrical conductor or circuit part within which a shock hazard exists.
.
Restricted Approach Boundary (Shock)
an approach limit at a distance from an exposed energized electrical conductor or circuit part within which there is an increased likelihood of electric shock, due to electrical arc over comb
