2. Install the MGB flat, if necessary, to ensure that no paths to ground turn upward to allow
connection to the top of the MGB.
3. Properly ground the MGB at a roof top site by two separate electrically continuous paths to
ground where practical as determined by the responsible Itron Project Engineer. The paths
can be in order of preference:
Grounding Building Steel and Existing Building Lightning Protection or
Grounding Systems
1. The first path to ground includes bonding the MGB to building steel with a 4/0 AWG
conductor. Consider only building steel that has been verified by the AE to be continuous to
earth and appropriate for grounding.
2. Install the second path to ground by bonding the MGB to the existing building lightning or
grounding system with 4/0 AWG conductor.
Grounding Building Steel and One 4/0 AWG Down Conductors
1. The first path includes bonding the MGB to building steel with a 4/0 AWG conductor.
2. Provide the second path by installing a 4/0 AWG down conductor from the MGB to the
ground rod or chemical ground rod. Use the water pipe main entrance if the ground rod or
chemical ground rod are not available. Do not use AC service panel grounds.
3. If the Itron TCU / CCU equipment is located on the ground floor or in the basement, the MGB
may be connected directly to both building steel and the water main or ground rod.
Grounding One 4/0 AWG Insulated Down Conductor and One Existing
Building Lightning Protection Down Conductor or Building Ground
System
1. The first path is the installation of one 4/0 AWG insulated down conductor from the roof top
MGB bar to the ground rod or chemical ground rod. Use the water pipe main entrance if the
ground rod or chemical ground rod are not available. Do not use AC service panel grounds.
2. Install the second path by bonding the roof top MGB bar with a 4/0 AWG insulated conductor
to the existing building lightning protection system or building ground system down
conductor.
3. If the Itron TCU / CCU equipment is located on the ground floor or in the basement, the MGB
can be connected directly to both the existing lightning protection or building ground system
and the water main or ground rod.
Grounding One 4/0 AWG Down Conductor
Note: Use this option when neither building steel nor a building lightning protection or
ground system is available at the Itron TCU / CCU equipment location.
