Boat Bonding System Diagram

A bonding system provides an alternative path back to the power source that doesnt travel through the water thereby reducing although not necessarily eliminating the destructiveness of this type of corrosion. We recommend that a boat should have an electrical system survey once every 5 years.

Fuel tanks and fills should be linked with the main dc negative bus.

Boat bonding system diagram. Moreover all electrical equipment and large metal objects should be grounded to prevent electric shock and increase lightning safety. A wiring diagram is a streamlined standard photographic representation of an electrical circuit. This does not take long and does not cost much and can save you thousands of dollars in unwelcome headaches.

Over time boat systems degrade particular as respects to the effects of corrosion. Last year i encountered a situation where a well known and respected boatyard had added a bonding system to a 42 128m motor yacht. There should never be any current in the bonding system.

Second and relevant in the aforementioned vessels case when the bonding system is connected to a sacrificial anode as it always should be the anodes used aboard this vessel are aluminum then that anode will then afford protection to all metals that are interconnected and immersed in the same body of water. The bonding system included a wire to the metal housing for the bow thruster. Abyc develops the consensus safety standards for the design construction equipage maintenance and repair of small craft.

It shows the components of the circuit as streamlined forms and the power and also signal links between the gadgets. They used 8 wire for the system and did a nice and tidy job of it. Battery monitors inverters ac systems grounding systems.

For the most part all metals touching sea water should be bonded including seawater pumps strainers and plumbing. A separate system electrically connecting all metal fittings on the boat that are in contact with the water including the sacrificial anodes and connecting them to the earth ground so they are all at the same voltage potential zero. The ground connection is usually made by clamping to a metal water pipe or by driving a long copper stake into the ground.

The development of uniform standards is the basis for industry wide comparisons of products and performance. Bonding systems also mitigate galvanic or dissimilar metal corrosion. On a boat things are considerably more complicated.

American boat yacht council inc. It consists of the green grounding wire in the ac wiring system and serves the purpose of preventing shocks or electrocution. How to test for continuity resistance voltage potential and stray current flow in a boats bonding system.
