Jim,
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.

Larry, my 2001 reference says 2% for voltage drop. It also says
that #8 in a three wire bundle will handle 40 amps.

I forgot to mention.
If you size the wire for the current, the 5% rule comes in at about
125 feet IF I remember correctly.
