1/2" conduit is a bit tight, particularly on longish runs the 8s
already in place. This site has a useful conduit fill calculator:
http://jlgengsoft.com/Documents/fill.htm Exactly how hard did they
try to pull out the offending wire? It's possible they damaged the
insulation. Is the work being inspected or are you relying on what
these guys tell you?

You don't have to pay for work that isn't done, but then again, I
don't know how that change order was worded. These were the guys that
kept requesting new boxes of connectors when they hadn't finished a
single box and kept scarfing your beverages. Rack up another one.
Your next step is to find out if these guys are really licensed.
Using a buddy's license doesn't cut it.

Well I started watching them closely, they were not taking my stuff, just
exceedingly absent minded.

Last week, one of them left about a half reel of 12/2 MC cables in the
attic, it was a reel of 250' long cable about half used.

But then again, I found tons of crap in my attic, I found about 65 brand new
(but 35 years old) AC filters up there today.
