H - 8 DOCKSIDE OPERATION
If any abnormalities appear during dockside
operation, DISCONNECT the system immedi-
ately to prevent electric shock hazards! Have
the boat’s electrical system and the shoreside
receptacles checked as soon as possible.
A. Shore Power Connections
To prevent electric shock hazards, use only
equipment with approved three wire electrical
plug connections. Be sure each item being
used has been tested and is free of electrical
shorts and ground faults.
Fifty.foot,.ten.gauge,.three-wire,.shore.power.cords.
are.provided.with.dockside.wiring..The.shore.power.
cords.on.60.Hertz.systems.have.30.amp.twistlock-
type connectors. They have a power ”ON” indicator
light.to.ease.in.connecting.and.troubleshooting..This.
connector.complies.with.the.American.Boat.and.Yacht.
Council.(ABYC).standards.
Some.marinas.are.not.equipped.with.approved.
twistlock-type.receptacles..An.adaptor.is.available.
from.Four.Winns.which.converts.the.twist-lock.shore.
plug.to.a.three-wire.grounded.household.type.plug..
Use.only.an.approved.adaptor.when.an.adaptor.is.
necessary.
DO NOT use a two-wire adaptor to connect to
a three-wire system. These adaptors do not
provide adequate grounding.
Shore.power.connection.procedure.is.as.follows:
1.. Turn.off.the.boat’s.main.breaker.switch.before.
connecting.or.disconnecting.the.shore.power.
cable.
2.. Connect.shore.power.cable.to.the.dockside.inlet.
receptacle of the boat first, then connect it to
dockside.shore.power.outlet.
NOTICE
Always connect the cord to the power inlet
receptacle of the boat before making connec-
tions to the shore power source.
3.. Check.for.reversed.polarity.on.the.AC.panel...
If.the.reversed.polarity.light.is.activated,.immedi-
ately.disconnect.the.shore.power.cord...
See.Section.H-8C.-.Reverse.Polarity.Indicator.
