3. Run a cable harness through a left side JCOMM knockout leaving the five-connector end near the main or
subdistribution feed CTs.
4. Connect the cable harness to the 10-pin connector for the corresponding main feed or subdistribution feed
connector (1 or 2) for this BCMS at the bottom of the JCOMM Connections Panel (
Figure 7 ). (There are
two main feed or subdistribution feed connections for each BCMS.)
5. Each cable harness has five labeled connectors (ABCNG). Connect split-core CTs ABCNG to the
connectors with matching labels on the cable harness for those phases being monitored.
