15.3 Apparatus not requiring earthing
Where there is no requirement for earthing or bonding, for example, in some types of
electrical apparatus having double or reinforced insulation, or for which supplementary
earthing is not necessary, an internal or external earthing or bonding facility need not be
NOTE Double insulated apparatus, while not presenting a risk of electrical shock, may need to be earthed or
bonded to reduce the risk of ignition.
15.4 Size of conductor connection
Earthing or equipotential bonding connection facilities shall allow for the effective connection
of at least one conductor with a cross-sectional area given in Table 5.
In addition, earthing or bonding connection facilities on the outside of electrical apparatus
shall provide effective connection of a conductor with a cross-sectional area of at least
