I have a superwinch S9000 winch and am trying to figure out what size fuse i should use, if any fuse at all is recommended.

The loads for the winch are:

73 amps at 0 load
130 amps at 1000lbs load
165 amps at 2000lbs load
240 amps at 4000lbs load
316 amps at 6000lbs load
420 amps at 9000lbs load

Remember you opinion does matter

Thanks

 

A fuse is highly recommended. And a circuit breaker is even better than a fuse.

Buy the biggest wire that you can afford. Buy a "Slow Blow / "Time Delay" circuit protector that matches the size wire that you buy.

 

JK-Ford the winch has a #2 cable for the hot side and the ground. So i guess i need a 150amp circuit breaker for the #2 cable.

I do have a isolation solenoid located between the battery and controlled by a switch on the dash so the winch only has power when needed.

Let me know

Thanks

 

I agree. I also recommend a quick disconnect for the battery. I keep my winch disconnected, unless I plan on using it. If I do, it takes 2 seconds.

 

Ya I normally don't like the wire ampacities rating based on length. But DC motors connected to batteries present a new concept to me. Normally I would say to wire the motor to its full load capabilities. But I don't think that installing a 400 amp circuit is very applicable either. So I force myself to a compromise. If you can afford it, I would recommend wiring a 200 amp circuit. And make the connection to the winch as close as possible to the motor. I really have no clue how often you may see high current during a recovery. But if it were my winch, I would want the most capabilities that I could possibly engineer. Good luck with your install.

Hope this helps.
