2.7.1 C: 

Replace the subclause as follows: 

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) and c): 

a)  except as detailed in b) and c), protective 

devices necessary to comply with the 
requirements of 5.3 shall be included as 
parts of the equipment; 

b)  for components in series with the mains input 

to the equipment such as the supply cord, 
appliance coupler, r.f.i. filter and switch, 
short-circuit and earth fault 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 the building installation shall be 
regarded as providing protection in accordance 
with the rating of the wall socket outlet.
