Basic requirements

To protect against excessive current, short-circuits and earth faults in PRIMARY
CIRCUITS, protective devices shall be included either as integral parts of the
equipment or as parts of the building installation, subject to the following, a), b)

protection may be provided by protective devices in the building installation;

c) it is permitted for PLUGGABLE EQUIPMENT TYPE B or PERMANENTLY
CONNECTED EQUIPMENT, to rely on dedicated overcurrent and short-circuit
protection in the building installation, provided that the means of protection, e.g.
fuses or circuit breakers, is fully specified in the installation instructions.

If reliance is placed on protection in the building installation, the installation
instructions shall so state, except that for PLUGGABLE EQUIPMENT TYPE A
