Guys:
Yes, the disco before the meter has been around for a while, depending on your POCO

PSE&G has 'HOT' sequence & 'COLD' sequence requirements. 'COLD' seq. translates to the disco before the meter, allowing the meter tech to do his/her thing 'dead'. Mostly on self contained 277/480, 200 amp.

JCP&L (GPU/First Energy) IMHO changes like the wind, or maybe it depends on the Field person.

Alas, the immortal words of the Great Sage...
TALK to the POCO guy....before you get into the job!!
