The lower end of the upper cable section
is fitted with a lower termination, and
the upper end of the lower cable section
is fitted with an upper termination. The
lower termination inherently has a lug
termination, but the upper termination
needs to be fitted with a bonding
termination (ERICORE/UTSP) and lug
(termlugcoup) to allow it to be lugged.
Each of these two lugged terminations
must be electrically bolted together and
to a suitable conductive structural point. In some installations, both lugs can be
directly connected to a suitable
conductive structural point, but in some
installations it will be more convenient to
connect both lugs to a small busbar, and
have this busbar connected to a suitable
nearby conductive structural point. Note
that the conductor used in this case must
be a minimum of 16 mm
2 (4 AWG) and
should not exceed 5 m (200 in) in length. A
suitable conductive structural point may be
either structural steel work or the
reinforcing within concrete panels or slabs.
These joints should not be exposed to the
weather and are usually located in a
service shaft. Very tall buildings will have a
number of connection points depending on
their height.
Details of where to provide the joint will
be provided by the ERICO application
engineers, after consideration of the
building details.
