I am putting a subpanel in the basement (Tigard, Oregon). There is
already a 6/3 copper cable run down there. This cable will be attached
to a breaker in the main panel. What is the maximum size breaker I can
use? I have read conflicting stuff. Is it a 50 amp or 60 amp breaker?

How long is the run from the end of the 6/3 cable in the basement
you want to install the sub-panel from the main breaker panel it will
fed from... If it is a long run, your ampacity on that line will be
as you would have to run a bigger sized wire to compensate for the
greater distance from the main panel to get the same amperage service
to that location...
You see this in situations sometimes when you have a circuit that
a distant part of your house, far away from your breaker panel, you
run a wire a size larger than you what is "needed" to compensate for
