Thats kinda overkill... which is cool, but for a single constant power source some 14/2 wire with an inline fuseable link with the right amp fuse and shore plug will do just fine for your fridge considering it only pulls 1-1.5 amps on the fridge setting. Thats how mine has been running for the last 2 years and thats how AT trailers were wired for the fridges also in the past... So far so good :sombrero: Remember your plug may have a fuse, plus the fridge fuse along with your fuseable link is plenty of overload protection.
