CBs for fuses

Given the pros and cons ... question: does a change from fuses to CBs require either an STC and/or 337? (I have to fuse the installation of the alternator and figured that "as long as I am at it ..."! :wink: )

Does not require an STC (although there may be some out there). It does require a Form 337, but does not require Block 3 approval (field approval.) IMO

Hmmm

I changed from fuses to breakers at the same time I installed the alternator STC. It's just another line on the 337.
