Fault Protection;  Protection against electric shock under single fault conditions.

Provided by automatic disconnection in the event of a fault. (Reg 411.1)

Additional protection; only RCD's set to 30mA and operating within 40 mS at 

150mA comply.

Additional protection MEANS additional to FAULT protection and to BASIC

protection. (reg 410.3.2)

Reg 415.1.1 makes mention of careless users.

This means that RCD's are provided to provide ADDITIONAL protection

if basic and fault protection fail.

Careless users can be domestic users.

Domestic and commercial can be "instructed" users.

HOWEVER;  the use of RCD protected sockets may be needed

within some areas of these premises.
