Yes maximum size breaker 50 minimum ampacity 30.9. I would have used #10 before.
but I thought he could only use this wire for the given application (article 440) under 2 conditions:
1) 60 degree column works (it doesn't, he needs next size #8)
2) per 440 (or 430 per 440.7), the unit is marked and says on the label "max size breaker 50A" (he didn't say this but I am guessing everyone assumed it ?)
#10 would be fine if it were piped.Yes maximum size breaker 50 minimum ampacity 30.9. I would have used #10 before.

Scrape the .9 off of the tag.
So I'll use 8 to the disco. #10 to the unit.
All wire references are copper.
Unless you want to change to some other wiring method than NM.

With all the talk about the 60 degree coloum in 310.16. I am second guessing my self. Is #10 Romex okay on a 240 v Geothermal Heat Pump? The breaker will be 50 amps, the minimum circuit ampacity is 30.9.
Is romex #10-2 WG okay?
