Circuit breaker ideas

[zippyduck]

Looks like my circuit breakers could use replacing. There is a 30 amp breaker on each battery of a 36 volt system.
Should I go with the same or is there a better idea.

Zippy,  seems like the single battery feed going to your trolling motor should be at least 50A and depending upon the motor perhaps a 60A.  It will be clearly stated in your installation manual for the trolling motor.  I have no idea what the purpose of three 30 Amp breakers are doing with your trolling batteries.  The values are not cumulative so you are actually running on a 30 Amp breaker going to your troller and that most likely is not enough.  Check your Manual.  Heck, My 24V Minn Kota requires 50A to 60A on a two battery circuit.  I have no breakers between the batteries.  Now it makes me wonder just what is the size of the wire going to your trolling motor.  With the kind of luck you have been having it just might be too small and need replaced.

Bud,
The wiring is extra heavy duty.

There is a 30 amp on two of the batteries and what looks like 2 30 amps bracketed together on the 3rd. I've never seen this and will be upgrading soon.

Where should I look for these kind of circuit breakers.

Zip I'm not sure on a 36 Volt System what size you need for a Single Breaker.

Most 24 Volt use a 50 Amp, I'm pretty sure.

The Old Rule Of Wiring was 8 Gauge for 12 Volt TM, can be used for 24 volt.

6 Gauge for 24 Volt is Preferred.

Not sure for a 36 Volt System, but I'd think it should be At Least 6 Gauge.

Since you just Bought the TM, did it come with a Owners Manual? If so there is probably a section in it that says what size Breaker to use.

Now where to get them. Places like US Boats and Others.

Here is a Link to a page that carries several styles:

Good Luck man and I hope this is the last bit for you. Really sucks when you get something New To You and the former owner didn't take care of it.

Bud hit it on the head. The 3 breakers you have aren't doing anything for you. You need a single breaker on the hot 36v  feed going to the trolling motor.

The new trolling motors don't pull the amps the older ones did while producing more thrust. I've got a single 50 amp auto reset on my 36v 112 ft/lb Ulterra.


If you don't have pieces leftover, you didn't put it back together right...

FD is correct, those breakers aren't doing anything for you the way they are configured and 30 amp is not heavy enough for 70 to 100lb thrust trolling motors. You most likely need a 50 or 60amp. I don't remember which TM you have.


You want a waterproof marine breaker on your main feed (+) close to the battery.

I'll echo others here also. I have a single 60amp breaker mounted right near my batteries.

I have a 60amp breaker in my Stratos and it's mounted right next to the Trolling motor batteries.  I have a 24volt system.

Yes guys the instructions call for a minimum of a 50 amp to 60 amp breaker. This will be my project on vacation this week.
