Just an update -- I haven't maxed out the Planer yet since replacing the breaker, but I did just run a bunch of 9" wide 8/4 walnut. Prior to breaker replacement, stock this wide (and generally, anything over 8"), was causing the breaker to trip even on a pass limited to 1/64 depth of cut (equivalent to a quarter turn of the depth wheel), and at the slowest speed setting of 1. Did not experience any problems, so I am hopeful that the breaker was indeed the culprit, and that the issue is now resolved.
