WARNING
The Residual Current Device (RCD) is basically provided
to protect the user from lethal electric shock. The RCD will
turn off (trip) if the current flowing in the live conductor
does not fully return down the neutral conductor, i.e. some
current is passing through a person down to earth or
through a faulty appliance.
To ensure the RCD is working correctly, the test button
should be operated each time the vehicle is connected to
the mains supply (see section 5.1)
The Miniature Circuit Breakers (MCB's) operate in a similar
way to traditional fuses and are provided to protect the
wiring installation from overload or short circuit. If an
overload occurs the MCB will switch off the supply. If this
occurs you should investigate the cause of the fault before
switching the MCB back on.
