Theory & SafetyPregunta 118 de 120
Entrances at each end of the working space are generally required for equipment rated at least what value and over 6 feet wide?
a.1,000 amperes
b.800 amperes
c.1,200 amperes
d.600 amperes
Explicación
Equipment rated 1,200 amperes or more and over 6 feet wide containing overcurrent, switching or control devices needs an entrance at each end of the working space so a worker is never trapped behind an arcing fault. The 1,000-ampere threshold belongs to service ground-fault protection, and 800 amperes is the ceiling for the next-standard-size overcurrent rule.
