How to Install an Energy Meter

Energy meters should only be installed by suitably qualified engineers, elecricians and elecrical contractors.To install an energy meter correctly, it is important to firstly choose the right meter (single-phase or three-phase meter depending on the power system, sizing in Amps and measurements required). The chosen meter can then be installed using the correct wiring in terms of connectin voltage and current inputs, made according to the relevant wiring diagram. How the meter is mounted and installed will also depend on its format (DIN rail, panel mount, wall mount, pole mount etc). The meter will also require protection from energy surges and short-circuits and must be installed with appropriately sized circuit breakers or fuses to prevent damage. Once installed the installation cannot be certified and signed off without verification and testing to ensure the installation is electrically safe and provided readings and accuracy required.
