Multi Meter Box Strategy:

•  Relocation & Grouping: Position energy meters
  outside consumer premises, especially in areas not
  easily visible from main roads, and cluster them
  together. This setup discourages individual
  tampering.
• Access Control: Design meters to be inaccessible to
  linemen, allowing only the outgoing connection box
  to be reached. This further reduces chances of
  tampering from inside.
• Enhanced Security with Multi Meter Boxes: These
  boxes, designed to accommodate multiple energy
  meters (single or three-phase), ensure connections
  end within the box. A locked metering chamber
  safeguards the meters.
• Shielded Wiring: Wires, both incoming and outgoing,
  are neatly organized and protected within the boxes.
  Cable tray covers are employed to ensure a neat,
  complication-free setup, making them invisible from
  the outside and reducing tampering potential.
