AWG BTCW.
In most cases, connect the other end of the ground leads to the equipment ground bar (EGB) or
MGB if each equipment cabinet has separate, external attachment points for ground lugs. If the
Itron concentrator equipment cabinets collectively have only one or two ground attachments, the
BTCW ground leads may be exothermically welded directly to the BGR.
TCU / CCU on a Concrete Pad
Use a concrete pad to hold the EGB flat. Several inches above the surface of the pad, securely
bolt the TCU or CCU with stand-off (cherry) insulators to prevent movement. In this
configuration, the ground bar is typically used only for Itron TCU / CCU equipment grounding.
TCU / CCU on a Steel Frame or I-Beam or Platform
If the Itron TCU / CCU equipment is mounted on a steel frame or I-beam, bond the steel to the
BGR at opposite ends with two No. 2 AWG BTCW and exothermically welded at each end.
Secure the BTCW ground leads to minimize the possibility of creating a trip hazard.
Ensure that all ground paths to the BGR are installed so that any potential discharge of electricity
is downward or flat. The MGB needs to be properly located to ensure that this is possible.
Warning! Do not allow ground paths to go upward. Make all connections to ground
bars in accordance with this document.
TCU / CCU on a Raised Metal Platforms
The following procedure outlines how to ground a CCU that is installed on a raised metal
platform.
Grounding the TCU and the CCU on a Raised Metal Platform
1. Bond raised metal platforms used to support the Itron TCU / CCU equipment at raw land or
collocation sites to the BGR at two locations with No. 2 AWG BTCW exothermically welded
to opposite sides of the platform.
For rooftop sites, the platform ground leads are connected to the MGB.
2. If the raised metal platform contains removal grating, install metal clips on removable
sections to insure the metal platform is electrically continuous.
3. Securely mount the MGB below the platform using stand-off (cherry) insulators to electrically
isolate the bar from the steel platform.
In this configuration, the MGB is typically used for Itron TCU / CCU equipment, coax cable,
and platform grounding.
4. Mount the MGB so that all equipment, coax, and platform ground lugs attach to the top two
rows of holes and the leads connecting to the BGR attach to the bottom two rows of holes.
