The Continental Control Systems WattNode BACnet meter connects to three solid-core toroidal current transformers positioned on phase conductors within a gutter wireway above the switchboard. Phase A, Phase B, and Phase C lines route through the current transformers while voltage references tie into a fifteen-amp three-pole meter voltage breaker. The unit receives power from line phases and neutral terminals alongside ground connections linked to additional meters. Communication wiring utilizes an FT-10 BACnet network daisy-chained to previous and next meters.
