[PSUBS-MAILIST] Motor Protection

[Cliff Redus via Personal_Submersibles]

 For the R300 I use a Minn Kota 60A breaker between the 36V positive side of the main propulsion battery bank and the Minn-Kotta 36V motor controller battery positive lug for each of the four thrusters.  https://www.amazon.com/Minn-Kota-1865115-Circuit-Breaker/dp/B0BNTH473G/ref=sr_1_3?dib=eyJ2IjoiMSJ9.ZqOoEUKfcSHKDAlJ0cWIA70Oc4GT_j_d2PWszPuhTWJKxouMgjblPHJLMyjyCTzUVzzKhbKa3aFouF0Co9REU9luDIalX7Wx6kp1cFJPwyPuuYZV0z5hmMnH6CRpR48gTvwUR21QRQy9K_gyenbVVYYVx_pkWRwskWwRa7xyb1r5CwEMopZwTCXnNz9SNO_O5qhD-NL4juaH57I41WnPpueYD1Uy8vMU2XunD5XiRUc.ri47ao09jgU4F9rIK7dgMLJO0nonViVRQgT8Tfwlpbs&dib_tag=se&hvadid=439258262771&hvdev=c&hvlocphy=9027968&hvnetw=g&hvqmt=e&hvrand=14591139276017572863&hvtargid=kwd-330092347103&hydadcr=9495_9892223&keywords=60+amp+circuit+breaker+minn+kota&qid=1716308917&sr=8-3
BTW, in 10 years of operation of the boat, I have never had one of these circuit breakers open.

 Hey gang, I'm curious what the general consensus is regarding fuse/breaker protection on both pos/neg legs of the propulsion motor or if protection on just the positive side is enough.
