Frequently Asked Questions

  • Do trolling motors need a circuit breaker?
  • It’s highly recommended for your trolling motor to have a circuit breaker. This reduces the short circuit problems and increases the longevity of your motor. You can try to use a 50 amp circuit breaker for your motor, depending on the ampere capacity.

    What size wire should be used for a trolling motor?

    Do trolling motors go bad?

    The average lifespan of a trolling motor is around 4-5 years. But if you want to increase it, you may try to install a circuit breaker. At that rate, some breakers may last for 10years too.

    How are circuit breakers selected?

    You may select your circuit breaker by observing nominal voltage, rated maximum voltage, continuous current rating, short circuit rated current at maximal voltage, voltage range factor, and operating time. These things will make sure the breaker you’re buying is excellent.

    Can I use a fuse instead of a circuit breaker, and what is the size recommendation?

    Yes, of course, you can use a fuse instead of a circuit breaker. For the size, the maximum amp capacity of your troller should be lower than the fuse amp size. For example, if the motor has a capacity of 38 amps, then go for a fuse that has at least 50- or 40- amp fuse.
