Structure Bonding Braid
To help ensure that the upper end of the
downconductor can be adequately electrically
bonded to the structure, a Structure Bonding
Braid has been provided at the base of the upper
termination of the downconductor. This braid is
a 75 mm (3 in.) tail which exits from under the
termination coldshrink and is supplied with a
connector to allow connection to a 6 mm
2
(8 AWG) copper cable (as mentioned in the
following text). This must be connected to a
conductive structural point to relieve the electrical
stresses on the downconductor and masonry
surfaces.
The use of the Structure
Bonding Braid is NOT optional,
and MUST always be used.
