I ordered a Bulldog 500187 electric trailer jack. The videos say you don't have to put in an inline fuse as it has a built in circuit breaker. I guess one could still put on in if they wished. What do you think? Do I need to add one or not? If so, what size? 30 or 40 amp? Any you recommend?
I would not add another fuse/breaker in the power feed line to the jack. After viewing the video, I presume they have installed a type 1 breaker inside the jack cover.
If you are running the power directly from the battery ( as many tongue jack are run) I would add a fuse at or close to the battery to protect the wire in case of a short.
