hi Mike_Riverside.
2-3 w/gnd sub-feeds. Some runs are as far as 350 feet from the meter room.
I'm comming up with roughly 12 volts or 5% drop @ 240....blows the 210.19(A)FPN....
every 4 feet, the problem is they are doing the three at a time with zip ties and drywall screws!
hmmm, messy...
well ok ..T310.15(B)(2)(a) , given 310.15(B)(4) {kick's the noodles out} means 6 conductors @ 80%. , so per 310.16 starting @ 100a we get 80A.
~This is all assuming it's AL,
and bundled per 310.15(B)(2)
~ The other issue is the tie wraps, i believe panduit had obtained a listing in recent years, but i'm not sure as to it's specifics.
~ The EMT straps may be an obvious listing violation to some (110.3(B))
~ 310.15(B)(2) Ex has an 02' change applicable to the derating of 'bundled' MC
