6.
The reliability conductive connection between the main part the equipment and the
separable part the equipment (lids doors) shall not influenced ageing deformation
of packing between both parts.
Inseparable terminals could made soldering, welding moulding.
The separable terminal for connecting the protective conductor the exposed conductive
part made screw terminal.
All exposed conductive parts electrical equipment mounted stage shall durably and
reliably connected the terminal for protective conductor.4.
The outward protective terminal determined for the connection separate protective
conductor for equipotential bonding.
6. Conductive connection these parts the separate
protective conductor represents equipotential bonding (main supplementary).
The inward protective terminal situated close the phase terminals and determined
for the protective conductor, which the part the supply cable.
According the way connecting protective conductors there are:
− separable terminals,
− inseparable terminals. situated the outer surface the exposed conductive
part equipment and used for connection with exposed constructive parts other equipment
and with extraneous conductive parts.
. Proper installation electrical equipment
As for the danger excessive temperatures, following measures shall carried out.
A washer ring shall inserted into the screw terminal for carrying over the contact
pressure effecting the conductor.CONSTRUCTION ELECTRICAL INSTALLATION AND EQUIPMENT 61
− where electrical monitoring earth-continuity used, the operating coils shall not be
inserted protective conductors. reliably conductively
connected the exposed conductive part the supplied appliance equipment.3 Terminals for protective conductors
According the purposes connection protective conductors can distinguish:
− inward terminals,
− outward terminals.3. One part separable terminals shall made corrosion
resisting material, preferably brass. For screw terminals determined for higher values current
than the springy element shall used
