Not if they remove that tape.Time to do some derating calculations.

WTH is all that #10 for???
How do you figure? What would you consider "maintaining spacing"?Its still considered bundling,

These cables are neither:See below note last two paragraphs.
These cables are neither:
"through the same
opening in wood framing that is to be fire- or draft-stopped
using thermal insulation, caulk, or sealing foam,"
If they were, or are to be, then the last two paragraphs apply.
According to 310.15(B)(2)(a) more than 41 current carrying conductors have to be derated by 35% Which means you could not even put a 15A breaker on those #10's. in the first picture on the left if I counted correctly. Hard to see actually how many conductors are there.
Sounds like some bad math.#10 would be 30 amp without derating. 30x.65=19.5 amps, which would allow a 20 amp breaker.
15A breaker since we round UP to the nearest standard breaker size.
40 x 35% = 14A = 15A breaker

This is awkward, but...
