220 Vac network
◊
The 220 Volt AC system is powered by the an electrical cable
connected to a shore power supply and the waterproof plug
mounted on the stern of the yacht (see diagram).
Caution: Remember to rotate clockwise for half a turn the plug into
the socket to activate the circuit.
◊
Remember that most dock outlets are equipped with an automatic
safety switch that cuts the power off above 2000 Watts.
◊
From the aft socket, power reaches the main electrical panel
through the 220 Vac blue breaker which includes a very sensitive
“differential” circuit that automatically cuts the power off in case
of the slightest short.
◊
From the differential breaker, the tension is measured with the 220
Vac Voltmeter (1) before reaching the circuit breakers on the main
220 Volt DC panel and the breakers.
220 Vac network cautions
• In spite of all the safety features built into the AC system (high
sensitivity differential breaker), 220 Volt power remains danger-
ous.
• Precautions, and maximum care are necessary at all times around
high voltage power.
• It is very dangerous to handle 220 Vac components, appliances or
tools in a wet environment or with wet clothing or shoes.
• Always cut off power when you leave the yacht unattended.
• Check the aft socket for corrosion or leaks.
• Inside the yacht all circuits are protected both by the differential
switch and breakers for all uses; but, between the aft socket and the
shore, the circuit is protected only by the shore power breaker on
the dock. Not all docks present adequate safety features. Take
great care!!
Caution: Spikes or drops in the 220 Volt (nominal) power lines are
frequent, especially in crowded marinas. Check for these variations
by keeping an eye on the 220 Vac Voltmeter. The system is designed
to withstand voltage variations up to +/-5% and will function
properly only between these parameters. If the variations should
exceed these values, disconnect immediately the whole electrical
220 Volt AC system by switching off the 220 Vac blue breaker.
