I must of ran into the same inspector. He would walk in and say,"Looks likeI've got one inspector who is so hung up on box fill that I write the # of conductors / #allowed... next to each box, just to save time. He stopped checking them.
a lot of wires in those 4sq (1900) boxes, did you account for box fill?"
"Yep." So the next job in his area I wrote the box fill on the covers of every
box and number allowed. He looks at the boxes, laughs and signed my card
and never questioned me again. A very good and thorough inspector BTW.
