I feel uncomfortable with it, but I and a lot of others, and a lot of Jeepers, don't use a fuse or breaker on the winch line...

I have a 185 amp breaker. Thought being I rather trip the breaker as a clue to use a snatch block and avoid overheating a winch motor running at max amps. It has never tripped yet. On a side note, after three years, the breaker has started to trip periodically, without any winch use, just radio and PS (straight line driving). Hit the reset and it works ok for another few weeks. Maybe age related issue?

I phoned WARN and a tech said that it is fine to have no protection so that is what I have. Like 70Bones stated I am uncomfortable with it. The fuse/breaker is there to protect the wiring from overheating. Intermittent usage is unlikely to overheat any reasonably sized wire , but a direct short between ground and the positive would probably start a fire if it is not protected. I will probably install a 300a breaker as close to the battery as possible. This will trip if the + cable makes contact with ground due to damage or abrasion but will not result in a nuisance trip when I am using it at its maximum capacity.
Until I buy and install such as breaker I am making sure that my insurance is in effect.

All circuit breakers, whether DC, or AC as in your home panel, degrade with each use, and will trip at a lower amperage than rated for with a bunch of operations.

I run master disconnect switches on all my winches just because a fire or battery explosion isn't nice. I have been running a 300 amp switch on a 9,000 pound winch since 1981 without a problem. They run from about 25 to 50 bucks on amazon and are probably not needed, but give you added safe just encase something goes wrong. A 180 amp switch is overkill for a 4,500 pound winch.
