IF a diesle generator has an arc flash label "HC DANGEROUS" on the electric gen end and the gen gets started at the transfer switch that also closes a 2000 amp breaker on gen startup, [transfer switch is a HC dangerous also]. How can this be started safe as per 70E ? Switch gear is rated HC 4. Generator startup could be for testing online or offline.
thanks to all for your help.
