Driving the electricity connection

All existing models of electric meters are designed to perform the same basic function - they measure the amount of electricity consumed by the consumer.Generally, for installation of electricity meters involve specially trained people.But with a strong desire to install such a device can be on their own.We just need to thoroughly understand the connection diagram and in all following instructions.

Remember: for all possible consequences of unauthorized installation of equipment accounting only answer you.

Types of counters and their key features

parameter	Klassifkatsiya electricity
The type of current	constant and variable
number	phase, single phase,three-phase
number of tariff	single- and multirate
un working mechanism	mechanical, electronic and hybrid electricity meters - rarely used intermediate version with digital interface, the measurement part of induction or electronic type, mechanical computing device
By type of connection	devices direct connection to the power circuit and the transformer connection devices that connect to the main circuit through special instrument transformers

on the market are two main types of counters: induction and electronic.They differ in the mechanism of action and the accuracy of measurements.

Induction model is rapidly squeezed out of the market.It actively contributes to the government.The main disadvantage of this category of devices is that they are very easy to "cheat" than happy to use unscrupulous consumers.

counters Electronic counters is more versatile, compact and accurate.An additional advantage of current models is the ability to configure them to work in multi-tariff mode.This point is particularly important for consumers living in regions with different rates for electricity during the day and at night.

Thus, choosing the form of the counter for self-installation, it is strongly recommended to give preference to modern electronic models.

Advanced meters are classified according to indicators such as the accuracy class and the rated current.The smaller the counter-class figure, the better it works.

Required rated current is determined on an individual basis.To calculate the check with the local office and sales allowable rate of active power installed per user.This number must be divided by 220 or 380 on the same depending on your power supply voltage.

For users connected to the three-phase network, usually set a higher threshold of active power, however, to use a three-phase connection in the home is not quite appropriate.

Important!When connecting the meter to the buildings for which the estimated value of the current exceeds 100 A further set of current transformers.Directly "embed" the measuring device in such circumstances will not work.

In such situations it is important to consider that the inclusion in the scheme of the intermediate elements can adversely affect the accuracy of the account, so the planning transformer circuits should be approached with knowledge.It is better to consult a qualified technician.

When choosing a meter is required to pay attention to the integrity of the seal and the remoteness of its installation.Seals can be found on the housing screws counter.The maximum allowable period of limitation for the installation of a seal-phase devices is 12 months, for three-phase - 24 months.

Self meter connection: what about this law says?

To avoid problems with service and sales, pre-contact your local representative for the contract and obtaining the necessary permits for the planned work.

employee said the service will give you the documents, in which among other things will be listed in detail the requirements to be observed before and during the meter installation.

law requires that the counters connected to the private houses were installed outside the premises.This is done to ensure that, if necessary, and sales officer can access your equipment.Owners of apartments required by law to install Accounting Devices in the general panel is located, as a rule, on the landing.

Operating diagram Connection

considers the complex connectivity options, we will not - leave them to professionals, becausewithout the appropriate skills to cope with this kind of work is unlikely to succeed.

easiest option - a single-phase connection.It is performed using a maximum of 6 cable and load.Wires ground, phase and zero are connected to the input of the accounting unit.The same wires are connected to the outlet.

before counter is set breaker.This makes for greater safety and ease of use.A small device will self-disable a house or an apartment from power in the event of any kind of dangerous situations.

To avoid problems with the service and sales, be sure to switch plombiruem.For this we use the elementary kit consisting of a DIN-rail mounting, seals and plastic boxes.

design of a typical electric meter includes a bus.This product is in the form of copper strips.For its fastening clips used dielectric.Along the length of the bus is made a number of holes for supplying electric cables and their subsequent attachment.This connection method is relevant if necessary combining several individual wires in a cable.

counter arrangement: basic rules and requirements

install electricity meters fulfill strict compliance with the approved rules.Primarily, we study the requirements for use of electrical safety of any type and purpose.

1. counter is set at a temperature not below +5 degrees.Accounting equipment, as well as any other electronics, does not tolerate exposure to cold.
2. When installing the meter on the street are building a sealed heated wardrobe for him.All the necessary materials and accessories are sold in specialty stores.
3. The meter is mounted on a height in the range of 1-1.7 m above the ground.At a lower placement of the device you will simply look uncomfortable reading.

For all other guidelines and rules you introduce power company representative service at the time of conclusion of the contract and to obtain other necessary documents.

Do you know at what height is best to install the sockets?no ?then read the article on our website - here.

Also be sure to read about connecting the meter circuit.

Step by step instructions for installing

counter First of all, prepare the set for the job.We need the following:

• counter and shield;
• installation tools with pre-insulated handles;
• insulators;
• breakers (machines);
• wire;
• fasteners (screws and nuts);
• voltage meter;
• DIN-rail.

Further work in this order.

first step

We learn is our mains single or three-phase.We count the number of required switches.

second step

Install an accounting device to the body of the protective shield.Mounting is performed using special clips from the kit.

third step

Set switches.They will be fixed to the DIN-rail a special spring-loaded latch.The very same rail with screws to fix the pre-post insulators.

fourth step

Perform installation and grounding protective tires.Fasten them to the DIN-rail or as insulators in the case of the protective shield.Fixing screws and nuts perform.Tires placed at such a distance, the probability of circuit wiring has been ruled out.

First, connect the load on the switch, then connect the machines to the counter and only then carry out the connection of the accounting device.

fifth step

connected load.Phase allowed on the lower clamp circuit, zero connect with zero tire and the ground wire is connected to the ground bus.

sixth step

Set the jumpers that connect terminals on top of our machines.Jumpers are sold in specialty stores.Pre-buy the right amount of jumpers on the number of machines.

seventh step

Connect the electricity meter to the load.To do this, the output of "phase" (the third terminal of the accounting device) connected to the upper clamp machines.Next, connect the output of "zero" (represented by the fourth terminal of the accounting unit) with zero tire.

eighth step

Fix the housing electric meter panel on a wall or other suitable flat surface.We maintain a convenient height.

ninth step

find the phase and ground zero.In the absence of grounding check the special indicator each core.This simple tool will help us to find the phase.If the ground is present, you can easily recognize it - usually this vein painted or marked in green.

tenth step

Turning off the electricity supply to your home or apartment.

Eleventh step

We connect zero wire to the third terminal of the counter and the phase cable is connected to the first terminal.

twelfth step

Check meter operation at idle, and then gradually serve the load.

Thirteenth Step

their local distribution and sales services to further verification and sealing equipment accounting.

This work handwritten installation and connection of the electric meter is completed.

Congratulations, you have successfully coped with all the activities and save money on the services of third-party installers!
