How To Wire a Single Phase kWh Meter? 120V/240V & 230V AC – NEC & IEC
In the following step by step meter installation guides, we will show how to wire a single phase electric meter for 230V AC (UK, EU based on IEC) and installation of single-phase 120V and 240V (US based on NEC) regulations for existing or new mains service installation.
For general and clear illustrations, we have used the RED color for Phase, Line or Live wire while the BLACK color shows the Neutral wire. The color coded versions are also included for both IEC and NEC wiring color coeds.
Single Phase Meter Wiring for 230V AC – (UK & EU) – IEC
In UK, EU, Asia and IEC following countries, the single phase supply of 230V AC is provided by two wires systems (Phase & Neutral) from the transformer (Single-Phase 230V, or Three Phase 400/230V Transformer) to the meter box and further to the main distribution board in the residential premises.
An electric meter (aka energy meter or kWh meter “kilo-watt-hour”) can be digital (smart with an LED display known as electronic meter) or analog (electromechanical) having a rotating aluminum disk. Nowadays, smart electric meters are commonly used due to extra useful features and advantages over the old school technology, That’s why the Govt of UK required electric energy suppliers to install smart meters instead of analog meters.
Installation of Single Phase kWh Meter (1-Phase, 2 Wires, 230V AC Energy Meter)
First of all, make sure to disconnect the main power before working on electrical installations.
Starting from the left side for MAIN, connect the incoming (from transformer) Phase (Line) wire to to the 1st slot on the meter (Main).
Connect the incoming Neutral (N) wire to to the 2nd slot on the meter.
On the Load side, connect the Outgoing Neutral in the 3rd slot.
Now connect the outgoing Phase wire in the 4th slot and connect it to the main distribution board as shown in the fig.
Below is the basic connection diagram for installation of a Single-Phase, 2-Wires) kWh meter (Digital or Analog Energy Meter) from the 230V AC supply to the main distribution board in home.
