I've tried, but I don't see 22 wires in that pic. Are you sure you counted correctly ?
I don't know Tom personally but I'm going to go out on a limb here and say he can count. BTW, I saw 22. :grin:Nakulak, best I can count is 17.
Now I'm really confused.
Using Chapter 9, Table 4 for RMC and #12 THHW, I get:
0.220 sq.in. divided by 0.0181 sq.in per conductor = 12.15, or 12 conductors.
Using Table C8 for RMC and #12 THHW, I get:
Why are these numbers so different?
The best I new of was an apartment building turned condo turned offices. When they were gutting the building for offices the electricians found 2" pipe packed so tight that when they cut at a 1' section and held it to the light no light passed threw. One of the electricians knew someone who worked on the conversion from apt to condo and asked how did they pack it so tight for a pipe that went from the basement to the 4th floor. He was told they used pulleys tied to a truck hitch. Then theey tested the wires out and any ones shorted to ground became neutrals.
