Approved Grounds
This chapter describes the approved grounds appropriate for the single-carrier 
cabinets.
Definition of Approved Ground
An approved ground is the closest acceptable medium for grounding the 
building entrance protector, entrance cable shield, or single-point ground of 
electronic Private Branch Exchange (PBX) equipment. 
If more than one type of ap proved ground is available on the premises, the 
grounds must be bonded together as required in Section 250-81 of the National 
Electrical Code (NEC), or the ap plicable code in your country. 
Acceptable Mediums for Protective 
Ground
The following protective ground types are acceptable:
Grounded Building Steel. — The metal frame of the building where it is 
effectively grounded by one of the following grounds: acceptable metallic water 
pipe, concrete encased ground, or a ground ring. 
Acceptable Water Pipe. — A metal underground water p i pe, at least 1/2 inch 
(1.3 c m) in d iameter, in d irect contact with the earth for at least 10 feet (3 meters). 
The p i pe must be electrically continuous (or made electrically continuous by 
bonding around insulated joints, plastic pipe, or plastic water meters), to the 
point where the protector ground wire is connected. A metallic underground 
water p ipe must be supplemented by the metal frame of the b uilding, a concrete

encased ground, or a ground ring. If these grounds are not available, the water 
pipe ground can be supplemented by one of the following types of grounds: 
nOther local metal underground systems or structures — Local 
underground structures such as tanks and piping systems
nRod and pipe electrodes — A 5/8 inch (1.6 cm) (solid rod) or 3/4 inch
(1.9 c m) (conduit or pipe) electrode driven to a minimum depth of 8 feet 
(2.5 meters)
nPlate electrodes — Must have a minimum of 2 square feet (0.6 sq. meter) 
of metallic surface exposed to the exterior soil
Concrete Encased Ground. — An electrode encased by at least 2 inches 
(5 cm) of concrete and located within and near the bottom of a concrete 
foundation or footing in direct contact with the earth. The electrode must be at 
least 20 feet (6 meters) of one or more steel reinforcing bars or rods 1/2 inch 
(1.3 c m) in diameter, or at least 20 feet (6 meters) of bare, solid copper, 
4 AWG wire. 
Ground Ring. — A buried ground that encircles a building or structure at a 
d e pth of at least 2-1/2 feet (0.8 meter) b elow the earths surface. The ground ring 
must be at least 20 feet (6 meters) of 2-AWG, bare, cop p er wire. 
Approved Floor Grounds
Approved floor grounds are those grounds on the floor of each high-rise building 
suitable for c onnection to the ground terminal in the riser closet and to the Private 
Branch Exchange (PBX) equipment single-point ground terminal. Approved floor 
grounds may include the following: 
nBuilding steel
nThe grounding conductor for the secondary side of the power transformer 
feeding the floor 
nMetallic water pipes
nPower feed metallic conduit supplying panel boards on the floor 
nA grounding point specifically provided in the building for the purp ose
!WARNING:
If the approved ground or approved floor ground can only be accessed 
inside a dedicated power equipment room, then connections to this ground 
should be made by a licensed electrician. 
NOTE:
All protective grounds must b e electrically connected together to form a
