Screws used for electrical connections or
connections providing earthing continuity screw into
metal
Screw used for earth connection. N
Screws not of insulating material if their
replacement by a metal screw can impair
supplementary or reinforced insulation
N
Type X attachment, screws to be removed for
replacement of supply cord or for user maintenance,
not of insulating material if their replacement by a
metal screw can impair basic insulation
N
For screws and nuts; test as specified (see appended table) N
28.2
Electrical connections and connections providing
earthing continuity constructed so that contact
pressure not transmitted through insulating material
liable to shrink or distort, unless shrinkage or
distortion compensated
N
This requirement does not apply to electrical
con ne ctio ns in circuits carrying a curren t not
exceeding 0.5A
N
28.3
Space-threaded (sheet metal) screws only used for
electrical connections if they clamp the parts
together
N
Thread-cutting (self-tapping) screws only used for
electrical connections if they generate a full form
standard machine screw thread
N
Such screws not used if they are likely to be
operated by the user or installer unless the thread is
formed by a swaging action
N
Thread-cutting and space-threaded screws may be
used in connections providing earthing continuity,
provided unnecessary to disturb the connection and
at least two screws are used for each connection
N
28.4
Screws and nuts that make mechanical connection
secured against loosening if they also make
electrical connections or connections providing
earthing contin u ity
N
Rivets for electrical connections or connections
providing earthing continuity secured against
loose ning if su bjec t ed to torsion
