A 60 amp circuit breaker for inline or panel mounting. It takes 4 or 8 gauge cable with set screw fittings and weatherproof grommets. Why use a circuit breaker instead of a fuse? A breaker can be reset after it trips, so there is no spare fuse to carry. How do I pick the rating? Rate the main power fuse to suit the cable size, not the amplifier power, and fit it as close to the battery as you can. Ask the F.A.E. team if you are unsure.
