CHAPTER XI
BONDING
AIM!
The next step is the bonding system. The!
bonding system is actually a ground wire that joins!
all the metal fittings above and below the water!
line thus reducing the possibility of damage caused!
by lightning or electrolysis. For this reason,!
avoid sharp turns in the wiring. Refer to the D.C.!
electrical plan, sheet #8. The system must be!
independent of the D.C. or A.C. wiring.!
Do not use it as a return wire for the D.C. system.!
In fact, the D.C. system uses two wires throughout!
and never a common ground and the A.C. system uses!
two wires plus a ground wire.!
WIRE TYPE!
Use ffS AWG bare, multi-stranded copper wire. If it is covered, it should be green. The
system consists of a wire laid on the lowest part of the hull from front to rear and
connected to the ground plate of the bottom of the mast support. To this wire, all metal
fittings are connected. Don’t forget a direct connection between the filler cap for the
kerosene and diesel tanks. It is done to avoid a static electricity spark between your filler
cap and the re-fuelling nozzle. The chainplates (to which you have already connected a
terminal), seacocks, thru-hulls, tanks, bowsprit and even the stanchions should be all
connected to this system.!
