Terrova Breaker???

[Esox_Magnum]

Ok getting the new 80# Terrova next weekend and know about thje 60 amp breaker ect, my question is will the one in my rig currently work or will I need to change it. It currently is a 3 wire system with a 40 amp on both pos(+) leads and one 40amp on the neg(-).

It will work for normal use, but if you need to "put the pedal to the metal" it wont because you still are only limiting it to 40 amps. Your setup is giving you a little extra security by protecting all the leads, not adding any amperage in the breakers.

[Esox_Magnum]

Well then I guess I'll just eliminate that one and add a 60 amp, after the breaker it looks to be already 6ga to the plug...Not often I'll even run it on full bore though. Held up well on the 80# Maxxum I had on it but not sure what that pulled for max amps...

I think you are on the right track Esox,

When is the Iowa Musky Opener???

[Tom7227]

Don't want to hijack your thread but should it be on the positive or negative lead? My thought was close to the battery and on the positive lead to cut the power as fast as possible if you short out a wire on the boat.

[CAMAN]

Yes, always install a circuit breaker to the positive lead as close to the battery as possible.

"Not often I'll even run it on full bore though" Really???

Last year you had my 74 # Minn. on high for two days straight!!!

[Esox_Magnum]

I wasn't on high Del, honestly don't recall though. Rare I'm over 25 on my Maxxum in my rig, it goes to 100. Didn't matter anyway we got paid

I run a 101 Terrova off a single 40 amp breaker and have never had an issue...but I've also never had it above 70%.

Called Minnkota today. The tech recommended 50 amp breaker and 6 gauge wire for all TM installations.

[Esox_Magnum]

80# Terrova pulls 54 amps on max thrust...

[Tator2k]

Specifically asked about 24v 80 and 36v 101 lb terrovas

[Esox_Magnum]

101 only pulls something like 46 amps, just stating what other owners have found tripping the 50's on max thrust. Must be a reason Minn Kots now makes a 60 amp breaker....

[Ed Carlson]

I suggest you go with the 60 Amp on the 101. Less problems, and your good. Cost of the 60 over the 50 is nominal.

We had issues with the 50 amp on our 101 Max Pro. Went to a 60 amp, no more issues.

The other thing is be sure to use heavy 8 gauge wire in the installation beginning to end (they often say use 10 gauge, I suggest the use of 6 or 8 gauge). I also recommend only soldered cable ends, as crimps will eventually cause you issues too.

Good to know. Thanks guys.

FWIW - Switched my 50 out for a 60 last weekend as I was told that my new 80# Terrova pulled 56 amps on full. I figured I spent a pretty penny on the motor, and would want to make sure everything was safe and that I get the best performance possible out of it.

[Surface Tension]

The object with the breaker is to protect the wire and not the device.

If your load is 55 amps then you'll need wire size according to that. 6 gauge would be appropriate there with 60 amp breaker.

I know Minnkota's site talks more of length or wire used and that does have some bearing on wire size but IMO more emphasis should be made on what amp load.

A breaker that is tripping when a load is increased beyond its intended use is theoretically protecting the wire.

IMO that interruption is not good on the circuitry and probably one of the main reasons you see boards and AP fail.

On the same note, bad connections and wire too small dia for a motor means things get hot and reduce the life of the motor.
