RE: Dedicated 20 amp line - wire type/gauge?

With #10 wire (solid or stranded) max distance before voltage drop would be 57 feet-
If the distance is greater - look at #8, for 90 feet of distance.

The damage is Voltage drop at or near load - which can be significant if not accounted for-

In a work situation I had an Ultra Low (-80C) Freezer that would not operate on a 10 amp (208VAC) circuit w/ #10 at ~200 feet...
Happy Listening
