EN 60950-1:2001 section 2.6.4 deals with this subject. Separate terminals
must be provided for the "protective earthing conductor" and for the
"protective bonding conductors". For permanently connected equipment and
pluggable type A or B, all can be connected to the same stud provided the
protective earthing conductor is placed first with a nut to separate it
>from the protective bonding conductors.
We always use separate terminals, one for the protective earthing and one
for the protective bonding conductors. Each is marked according to
Section 1.7.7.1 of EN 60950. Lock nuts on the protective earthing add
security and means that there is no reason to disturb the protective
earth conductor during maintenance or servicing.
