Hey Patrick! The Redarc Tow-Pro Liberty # RED52VR calls for a 30A circuit breaker or fuse on the power wire as close to the battery as possible. See the diagram below.

Hey Patrick, did the 30A fuse work well with your Redarc Tow-Pro Liberty brake controller? I'm curious to know how it turned out for you, as it could help others looking to set up their brake controllers.
