The 600 Ampere busbar from Blue Sea Systems, PN 2104, also is useful for supplying high current to large loads.
When you supply high current to large loads such as a windlass, an inverter, and a DC Main circuit breaker panel, you may want to use a 600A busbar on the positive side of the house battery circuit. Instead of connecting multiple terminals to your battery switch stud, use this high ampacity busbar.
Be sure to include circuit protection. Choose the appropriate fuse or circuit breaker for each application.
