B-P MARINE Battery Master Switch
Control your boat’s battery connection with B-P Marine part 700074, a battery selector designed around the stated operating positions.
The selector format lets the battery arrangement be controlled at a dedicated switch. Check the operating positions and wiring diagram against the intended single- or dual-battery setup before installation.
Check the stated body dimensions and terminal access against the proposed mounting location. Allow enough room for the connected battery cables and for normal operation of the switch.
Continuous, intermittent and cranking figures describe different operating conditions. Keep any stated time limits and voltage conditions with their corresponding ratings when comparing switches; the highest number does not describe the allowable continuous load.
Choosing and using this product
Choose the component for the actual circuit and power supply. Compare the stated voltage, current rating and switching or connection function with the equipment it will serve. A similar faceplate or connector shape does not establish the same electrical specification.
Plan the component together with the circuit wiring and protection. Follow the equipment instructions for the required connections and ratings, and keep the installation accessible for inspection. A component rating should not be treated as the rating of the entire assembled circuit.
Keep circuit labels and the fitted product reference with the boat’s electrical records. This makes later fault-finding and replacement enquiries more straightforward. Before returning equipment to use, check the completed installation and its operation using the applicable instructions.
Check the exact supply format when ordering service parts. A replacement cover, boot, label, fuse or switch is distinct from a complete panel or assembly. Match the existing model and the stated part reference so that the item renews the intended component.
