Electricity Meter Wiring Diagram
In these step by step meter installation tutorials we show you how to wire a three phase electric meter for 400V AC for 3-Φ & 1-Φ 230V supply (UK, EU based on IEC) and installation in single phase & three phase 120V, 208V, 240V, 277V and 480V (US based on NEC) regulations for existing or new electrical service installations.

For general and clear illustration, we have used RED, YELLOW and BLUE colors for phase, line or live wire, while BLACK color shows neutral wire. Color coded versions are also included for both IEC and NEC color coded wiring.
Connecting a three-phase energy meter for 400V, 120V, 208V, 277V, 240V & 480V, 347V, 600V – IEC & NEC
Warning: These examples show the most commonly used setups and generic wiring for electric meter installations in the UK, EU, India, Pakistan, South Africa, United Arab Emirates and other International Electrotechnical Commission (IEC) countries. The same rule applies to the NEC (National Electrical Codes) in the US and Canada. Depending on the specific areas, the design of the meter (smart electronics or electromechanical) and the supply system, there may be some variations. The setting may be different for other types of kWh or electricity meters in different places in the world. For good security. Contact the service and equipment supplier to confirm the quality of the connection before installing the wiring.
Be aware that in some cases it is dangerous and even illegal to do your own electrical work. Contact a licensed electrician or electricity supplier before making any changes/modifications to electrical wiring. In addition, he must obtain the necessary licenses and approvals from the local government before installing existing or new services.

Be careful not to touch a metal tool in the screw terminals when the circuit is live, especially in the case of a 230V and 400V meter (IEC), as the terminal block screws are not insulated.
The author is not responsible for any loss, injury or damage resulting from the display or use of this information or if you try a circuit in the wrong format. So please! Be careful because it’s all about electricity and electricity is too dangerous.
In the UK, European Union, Asia and IEC in these countries, the three-phase 400 V AC supply is supplied in a four-wire system (three phases (line) and neutral) from the three-phase 400/230 V transformer to the master box and beyond . The main distribution board in residential buildings.
The good thing is that you can find a single phase 230V supply in a three phase meter charging point. All you need is just a single phase wire and a neutral. If you need three-phase 400V, all three lines and neutral (optional) are required to power three-phase circuits such as 3-Φ, induction motors, etc.

Currently in the UK the government requires the use of smart and digital electricity meters instead of analogue electromechanical kWh meters.
Good to know: An electricity meter is also called an energy meter, kWh meter or kilowatt hour meter and is used to read and record energy consumption and power consumption in kilowatt hours.
Below is the basic connection diagram for the installation of a three-phase, 4-wire, Wye-400V) kWh meter (digital or analog energy meter) from the 400VAC supply to the main distribution box in the house.
It is recommended to install the meter vertically on the centerline. After installing the screws, etc., make sure to close the safety windows. You can turn on the main switch after successful isolation of the three phase master box to check if everything works as expected.

Here is another real operational 3-phase energy meter installed on the electricity pole at the consumption unit.
A 38mm (38mm) (tubular iron) hockey stick and main box must be installed to the following minimum specifications.
The general wiring of the three phase meter (IEC color coded) from the mains to the main distribution board is as follows.
The story is completely different in North America compared to the UK, EU and the rest of the world. Single phase and three phase voltage levels in the United States – NEC for example differ compared to IEC in these countries as the usual single phase voltage level is 120V, 240V. In addition, both single phase and three phase voltage levels of 120V, 208V, 240V, 277V & 480V are available in the 7200V transformer on a utility pole.

In these sections we show how to wire an electric meter for 240V three phase and 208V three phase & 480V three phase & 600V three phase according to NEC.
Note: If the neutral conductor is not present in the master box, only 208V is available. If there is a neutral wire, both 120V and 208V are available in the panel box, i.e.
Note: If the pipes are not properly connected to the meter cupboard, or the meter points are not properly attached to the pans, it will not read the kWh reading and you may not be able to calculate the electricity bill based on energy consumption. In addition, improper connection of the meter can trip the circuit breaker or cause a flash, damage to the meter, or even serious injury and a dangerous fire.
Let’s see how they wire 1-phase & 3-phase, 4-wire or 3-wire, 120V, 208V & 240V AC electricity meters.

Note: If the neutral wire is not available in the master box, 208V single phase is not available. If there is a neutral wire then 120V, 208V and 240V are available in the panel box i.e.
Let’s see how to connect a 1-phase & 3-phase, 5-wire or 4-wire, 277V & 480V energy meter.
Note: If the neutral conductor is not present in the master box, then 277V single phase is not present. If there is a neutral wire, 277V and 480V are available in the panel box, i.e.
This is only a three-wire phase meter, ie no neutral and single phase system included. There are 5 jaws in the meter box without neutral, but ground is always connected according to the NEC.

The connection diagram of this meter is the same as for 277V & 480V (1-P & 3-P). There are 7 jaws, ie neutral, included for single phase supply of 347V.
*Neutral format determined by load calculation and NEC 250.122 table. Always check with your local area codes.
Separation of gas and other meters: Minimum 3 to 5ft & 6 inches on the outlet side of the gas meter bar.

This section is subject to revision. Roughrider Electric Cooperative is not responsible for faulty wiring on the secondary side of the electrical supply.
Yes, but only on units up to 300 KVA. They won’t give anything bigger. Concrete block diagrams are available in the Diagrams section below.
No. But we will give the impedance so that the calculations can be done. The impedance numbers are printed on the outside of the transformers or can be obtained by calling our office.

What is the procedure to have Roughrider make a site visit to open a transformer, de-energize a service, or something like that?
Such a visit requires us to schedule a crew to visit the site. Please contact us to schedule a viewing time. Schedule is usually one week off. Plan accordingly.
Electricians will install their own plinth (not one from the co-op) and run their own wires to the plinth.
Roughrider will install counter tops, supports and temporary supports. Electricians should not attempt to install their own.
Electrical 3 Phase Energy Meter Wiring Connection
For temporary construction site power, is it permissible to use permanent utility transformers with the main line if they are already installed and withdrawn? Can an electrician install an extra 2 inches of conduit while the secondary is running, then pull the wire and plug in a 200 amp single phase meter?
During construction we hang the main loop. Once the outlet is connected, the electrician must issue a wiring certificate and a notice that the service is ready for meter and power.
CT Metered: Electricians provide the meter connection, CT enclosure and secondary wiring between the meter and the transformer, according to our specifications. See our part number list below. Electricians install a CT housing and lay the line between them
