Shore power
-240Vsystem
The standard shore power system consists of:
Input socket
Residual current operated circuit breaker
Main double pole circuit breaker
Polarity test system
Voltimeter
Six circuit breaker/switches
Input socket
Situated in the cockpit area, this is used to connect the boats system to the supply
from the shore. The standard socket is a 220/240V 15A type.
Residual current circuit breaker
(RCCB)
Situated in the egine
room/sail
locker between the input socket and the main
distribution panel, this is a 30mA type and is used to protect the system and its
users. This device will trip out if there is a voltage change between positive and
negative anywhere in the boats 240 Volt system after this unit.
Main double pole circuit breaker
Fitted in the distribution panel, this is used to protect the outlet system from
overloading. When the switch is on you will get a voltage reading on the voltimeter,
The standard loading is
ISA
if the total load exceeds this the switch will go to the
off position.
Polarity test system
Fitted in the distribution panel, this consists of three LED's, one orange and two
red, positioned on the distribution panel. It is used to ensure that the polarity of
the
supply
to the boats system is correct. When the polarity is correct the two red
lights will come on, if the polarity is incorrect the orange or orange and red lights
will light up.
