If you’re working on a service, there is usually no way to just turn the power off. For single and multifamily units and even some small commercial, the poco usually just issues you a work order number and gives the OK to cut the Buddco tag, pull the meter, disconnect the drop and do what you need to, then put it all back together and have the AHJ call it in after inspection. They just send someone out to install a seal on the meter can.
This system has worked fine around here for many years, so now all of a sudden NFPA 70E declares it to be too dangerous to perform without a full PPE arc suit? P-L-E-A-S-E!
I have the necessary gear, shield, hot sticks, gloves and insulated tools, etc., and know how to use them, so will continue to do so when needed.
Maybe page one of NFPA 70E should start with: “a licensed electrician that does not know how to safely work on energized equipment under 600V is not a qualified person.”
