Well its all about drop and mains "stiffness".
I am sure with your short run, ampacity is all you have to worry about.
My RCA BTA-1R1 manual calls for #8 for each conductor. I use #10 and
my run is comparable to yours. My TX branch feed is from a submain
fed with #6. The #6 run (150 amp mains) is about 60 feet and the #10
is around 25 feet.
