I was doing a reverse ride along with a new inspector. Condo conversion in a courtyard style building, built in 1928. Mostly, a real good conversion.
They totally redid the electric, with big 600 amp disconnects in the basement and multiple meter panels. Six service drops in all (for each of the six “sections” of the building. 6 units per drop with 100 amp service to each unit (one and two bedroom units).
This is the drop. Six (each) of the two hot legs and neutral (Excuse me, Paul. Grounded Conductors.). Each service had its own rigid pipe service entrance, take to the 6 parts of the building (into six different basement electrical rooms. BTW: The owners thought that the electrical rooms were great places to store their bikes. What a freakin’ mess!
Each incoming SE was at least a 6/0 (Maybe 8/0. They were most probably the width of my thumb. Please remember, this was a three year old conversion, NOT a temporary hookup.
But look at what the ComEd guys used for the drop. It couldn’t have been bigger than 2/0 or 3/0.
