BONDING EQUIPMENT TO INTERNAL GROUNDING (EARTHING) SYSTEM CHAPTER 5: INTERNAL GROUNDING (EARTHING) Continuous Equipment Grounding Conductor To MGB Irreversible copper crimp lug or split bolt connector To MGB Continuous Equipment Grounding Conductor Conduit or Pipe Removable tinned saddle-type ground clamp Metallic pipe or electrical conduit Removable tinned saddle-type ground clamp FIGURE 5-30 GROUNDING METHOD FOR METALLIC PIPE OR CONDUIT 5.5.1.7 METALLIC BUILDING STRUCTURE AND PIPING SYSTEMS Internal Perimeter ground conductor Metallic building structures and piping systems, steel roof trusses, exposed support beams and columns, drop ceiling grids, raised floor support structure, any metallic exposed building support structure and building frame when located within 2.4 m (8 ft.) vertically or 1.5 m (5 ft.) horizontally of the communications equipment, shall be bonded to the MGB, SSGB, or internal perimeter ground (earth) bus using one of the conductors and methods described within this chapter. See Figure 5-21 on page 5-35. No series or daisy chain connection arrangements shall be used. Each peripheral device shall be bonded to the MGB, SSGB, or perimeter ground bus using an individual equipment grounding conductor. 5-48 68P81089E50-B 9/1/05
STANDARDS AND GUIDELINES FOR COMMUNICATION SITES BONDING EQUIPMENT TO INTERNAL GROUNDING (EARTHING) SYSTEM 5.5.1.8 SURGE PROTECTION DEVICES (SPDS) RF SPD MGB All surge protection devices and outside telecommunication cable metallic shields including, but not limited to, items listed below shall be effectively bonded back to the internal grounding (earthing) system with a 16 mm 2 csa (#6 AWG) or coarser equipment grounding conductor by using the following requirements and connection methods described within this chapter: • Individual RF Surge Protection Devices • Primary Surge Protection Devices • Secondary Surge Protection Devices • Telecommunication Cable Metallic Shields 5.5.1.8.1 RF SURGE PROTECTION DEVICES RF transmission SPDs shall be bonded to the MGB within 610 mm (24 in.) of entry into the equipment shelter, equipment room or equipment area. A separate equipment grounding (earthing) conductor shall be used to bond each of these devices to the MGB or to a SSGB. RF transmission line SPDs may also be bonded directly to a SSGB, MGB, or the copper integrated entry panel with the proper securing hardware. GROUNDING CONDUCTORS 16 mm 2 csa (#6 AWG) MINIMUM RF SPDs GROUND BUS CONDUCTOR 35 mm 2 SSGB csa (#2 AWG) MINIMUM FIGURE 5-31 RF SPD BONDING TO SSGB WITH GROUNDING CONDUCTOR If RF transmission lines enter the building at a point other than where the equipment room or area is located, there is no requirement for SPDs to be installed at that location. The shield of the RF transmission line shall be effectively bonded to the grounding electrode system at the point of entry into the building or as near as practicable thereto (NFPA-70-2005, Article 820.93). 68P81089E50-B 9/1/05 5-49 MGB SPDs BONDED DIRECTLY TO SSGB
