Outdoor grounding system
Grounding electrode system requirements
The installation site must be equipped with a grounding electrode system (that is, buried
ring ground, copper clad rod, electrolytic rods, metallic water pipe, and so on). The site
grounding, including all Alcatel-Lucent B25 RRH4x30 antennas and antenna cable
shields, must be bonded to the grounding electrode system.
ring ground, copper clad rod, electrolytic rods, metallic water pipe, and so on). The site
grounding, including all Alcatel-Lucent B25 RRH4x30 antennas and antenna cable
shields, must be bonded to the grounding electrode system.
The grounding electrode system shall be installed as part of site preparation with a
sufficient number of pigtails. Electrically conductive materials in the vicinity that are
likely to become energized must be connected together and to the grounding electrode
system in a manner that establishes an effective ground-fault current path.

Buried ground conductors must be, at a minimum, 35 mm

copper wire. Exterior ground conductors must be, at a minimum, 35 mm

sunlight-resistant) copper cable.
Exothermic weld
Exothermic weld is recommended for grounding connections where practical. All
below-grade connections must be exothermically welded. Compression type, two-hole
(0.75-inch center) lugs or double crimp “C” taps are acceptable for above-ground
connections. The contact area where connections are made shall be prepared to a bare
bright finish, and be coated with an anti-oxidation material before connections are made.
