Electrical Systems
Grounding and Bonding
Definitions
The terms grounding and bonding are often incorrectly
used interchangeably. They are different systems that
can work together to provide solutions to common
problems and risks on the water.
Bonding is the process of connecting various metal
components in the boat to a common electrical con-
tact. This helps to reduce the chance of rails and
other metal objects carrying dangerous electrical
charges.
Grounding is defined as the method in which any elec-
trical potential is connected to the surrounding water
for the purpose of energy dissipation.
Properly designed grounding and bonding systems
incorporating zinc or aluminum anodes and bronze
plates will also help control corrosion of aluminum and
stainless steel parts.
Grounding
The negative terminals of both batteries and the nega-
tive cable from the outboard engine are connected
together at a negative buss bar located inside the con-
trol console. This negative buss bar serves as the
return point for the entire 12 VDC electrical system.
The accessory fuse block and negative terminal strip
also connect to the negative side of the 12 VDC elec-
trical system at the buss bar. The connections are
made with #8 awg black wires from each device.
Note: All grounding wires and cables are
black
