What size circuit breaker to pair with the NK180?Updated 8 months ago

The NK180 speed controller comes with over-current protection built in, so there isn't a need for a circuit breaker. You can read more about the protection and how to solve this issue by viewing page 36 of the owner's manual.

If you would like to have a circuit breaker connected for additional protection, a 30A circuit breaker would be recommended.
