Metallic Masts
Following installation of the TerraStreamer
®
ESE Terminal to a metallic mast,
it will be necessary to connect the metallic mast to a down conductor in
order to convey the lightning energy to the grounding system.
The connection between the metallic mast and the appropriately sized down
conductor should be completed by approved mechanical means or by
exothermically welding (TerraWeld
®
) the down conductor at a practical point
somewhere along the length of the mast.
Particular care should be taken to ensure that compatible metals are used
when connecting the down conductor to metallic masts (e.g. aluminum to
copper connections require an approved bimetallic connector).
It is important that a minimum of
one third
of the mast height be securely
fixed to the structure to which the mast is mounted.
