Electricity submetering in multi-unit buildings

Distinguish informational energy monitoring from meters used to bill occupants, which fall under trade-measurement requirements.

VERT / GREEN

For energy monitoring only, clearly separate it from billing.

JAUNE / YELLOW

Once a reading establishes an electricity charge, the device becomes a revenue meter subject to applicable requirements.

ROUGE / RED

Billing from unapproved CT sensors, breaking seals or modifying metering wiring: do not do it.
