Electrical Distribution & Protection
Distribute Power and Protect Your Electrical Circuits
A campervan electrical system needs more than a battery and charger. Distribution and protection equipment connects appliances in an organised way and provides appropriate protection for wiring and individual circuits.
Explore battery switches, fuse blocks, fuses and holders, busbars, circuit breakers and distribution panels. Smaller installations may use a straightforward fuse block, while larger systems can benefit from a more comprehensive main DC distribution arrangement.
Protection must be selected for the application. Voltage rating, current rating, interrupting capacity and cable size all matter. DC and 230V AC equipment are not interchangeable, and a battery switch does not replace fuse protection.
Need help specifying the components? Share your battery, inverter, charging equipment and cable lengths with CH Marine so we can help identify suitable distribution and protection products.
