Chemical Ground Rod Installation
If required, install chemical ground rods and bond the chemical ground rod to the BGR
with No. 2 AWG BTCW. Refer to the illustration under To install a chemical ground rod
on page 101.
To install a chemical ground rod
1. Auger a vertical hole in the earth with a minimum diameter of six inches. For ‘L’
shaped chemical ground rods, dig a trench 12 inches wide.
The depth of the hole must be six inches greater than the vertical length of the rod.
2. Remove the sealing tapes from the bottom of the unit only. Tapes must be saved and
made available for inspection by the contracted engineer to verify removal and proper
installation. For ‘L’ shaped models, remove only the tape on the horizontal section.
3. Position the chemical ground rod unit in the hole.
4. Mix the backfill material if required. Pour backfill around rod in augured hole. Fill up
to red "Bury to Here" marker. Do not overfill.
5. Place inspection hand hole box with cover over the top of the rod so that the cover is
at grade level. Use backfill or grout to stabilize box around the rod. Keep the breather
holes free of obstruction and debris. The top of the box should not contact the top of
the rod.
Note Protective cover box must be either concrete or PVC construction and must be
12 inches by 24 inches by 22 inches deep, or equivalent.
6. Remove the top sealing tape ONLY after backfill is complete. This prevents soil from
blocking the breather holes. Tapes must be saved and made available to the Inspector
to verify removal and proper installation.
When an Itron TCU / CCU / Repeater is co-located with another wireless service
provider’s site, bond Itron’s grounding system to the tower BGR, to another provider’s
ground system, or to the common ground ring to ensure that all ground systems are at the
same potential.
Perform bonding at the earth ground ring level using a minimum of No. 2 AWG BTCW.
When bonding to another service provider’s ground ring, connect the Itron ring at two
locations to the existing grounding systems.
The size of the wire depends on the distance between the two systems. In most cases, if
the two systems are located in the same compound, No. 2 AWG BTCW will suffice.
