12. Installation example: EM4880 or EM4833
Commercial building floor plan
Previously, building owners with dispersed loads would need to install energy meters throughout their facility – but the EM4800 provides a simpler solution:
80 mA and 1/3 V CTs support extra long lead lengths of up to 100 m (325 feet) – you can monitor loads throughout your facility with a single EM4800 meter!
Electrical Room #1
EM4880 or EM4833 meter, installed outside of Electrical Room, allowing easy access
Three-phase meter point with 80 mA or 1/3 V CTs. A total of 8 three phase meter points are shown.
Electrical Room #2
The EM4800 can even monitor panels on different floors within the building Note: the panels must share a common voltage reference
Conduit used to connect CT leads to EM4800 meter. All CT leads are up to 100 m (325 feet) in total length

13. Flexible communications
