•
The 220 Vac Voltmeter in the electrical panel, located just ahead of the switches and upon
the 220 V outlet (see page 57), starts functioning every time the yacht is connected to the
shore supply or when the generator is working, but only after having previously turned on
the 220 Vac Main Breaker switch; it indicates the existing tension in the 220 Vac yacht
network.
•
When living the boat, even for a short while, turn off at least the 220 Vac Main Breaker
switch or pull out the shore network plug.
•
Check that the shore outlet supplying the 220 Vac current keeps watertight and does not
oxidize.
•
The 220 Vac network is protected by the safety switch, connected to the 220 Vac Main
Breaker, and by a magneto-thermal switch for each service.
•
Between the safety switch and the watertight outlet, the circuit is protected only by the
safety switch in the mooring wharf power panels. However, please bear in mind that the
above-mentioned safety system is not always available.
Warning:
the 220 Vac system cannot tolerate changes in tension of over 5%;
therefore, if this should happen, you have to cut off immediately the 220 Vac supply by
the above-mentioned 220 Vac Main Breaker switch.
Magneto-thermal switches
1.
The magneto-thermal switches located on the electrical panel have a dual function:
-
activate or enable the various services;
-
protect the services and their system from excessive overload.
Warning on magneto-thermal switches
The cable sections have been calculated according to the power used by each service
provided. Do not overload any magneto-thermal switch by-passing it or replacing it
with one of bigger amperage.
•
If a magneto-thermal switch goes off, do not turn it on again before finding the possible
anomaly or short circuit.
