Do not change the location of the equipment independently. This arrangement of devices due to the layout of the building. You first need to know if you are suitable for single-phase meter. He works at a voltage of V. To learn such data in the technical conditions of supply. More information is on the scoreboard the old device. When you buy the device for energy metering is necessary to know the maximum power consumption of energy.
With this information, selected not only the device itself, but also the cross-section lead wires, machines protection. This files most often equal to 3 kW. The counters are: induction; electronic. Nominal and maximum current are always listed on the front of all meters. Select the device will be easy even for inexperienced consumers! The electricity meter is selected in the network settings. Moreover, the device must pass state inspection and sealing. If all conditions are met, the equipment you can buy.
The electricity meters can be connected in different ways: using a direct connection. The counter is included in the power circuit. So, connects to most single-phase devices to control the electricity in the apartments; with the help of a transformer. This type of connection is used in industrial plants. To install the equipment with their hands to prepare the following tools: the perforator; pliers; pliers; knife; line; building level; flat screwdriver.
If all the tools exist to get to work. Do not forget that before installing the equipment, it is necessary to disconnect an apartment. To check the absence of voltage using a screwdriver with an indicator. Do not use broken tools and does not allow water inside the device. Boxes made of non-combustible material and can be recessed and mounted. Depending on the wall material chosen mount.
After installation of the box are moving to the modular equipment. In front of the device for electricity metering should be protective switching equipment. Most often it is automatic double pole switch. It is needed in order to: to protect the device to account for the testimony from short circuits or from the fire, as well as for the further works related to maintenance of equipment; to limit the maximum allowable power.
All single-phase devices are connected with a specific schema. You may use the specific region or general practiced codes in the local area i. Single Phase V AC:. Three Phase V:. Related Posts:.

Hello, What is the best practice to wire a 3 bedroom apartment with two toilet, a kitchen, a seating room and 4 outdoor security lamps. However i will like to know the how many circuit braker and ratings that will be needed for, lamps, sockets, 2 water heater, etc Thanks in advance and looking forward to hearing from you.
Have need of a circuit to control 3 d. Any switch can turn on all horns at same time. Also could use a single timer to control horns but also must be able to be as an emergency alarm system. And have a command switch from the front office to override all in paralel. Any other questions- my phone is i am maintenance leadman at a manufacturing plant. Dear Sir, You are giving very good knowledge useful for electrical family. I request you to please send electrical technology subject to my mail also.

Table of Contents. Electricity is our friend as well as enemy at the same time, if you give it a chance to kill you, Remember, they will never miss it. Please read all caution and instruction while doing this tutorial in practical. Disconnect the power supply and make sure it is really swathed OFF before servicing, repairing or installing electrical equipment. To do so, switch off the main switch in the main consumer unit or distribution board. Please contact to the supply and service provider to confirm the connection type before installation.

Dear Sir, We have already done the experiment by connecting two parallel wires to two different energy meters, connected common single load of halogen lamps of 2 X 1 Kw, capacity each, both the lamps connected parallel, and each input and output connected to 2 X Wire resistance was 1.
Live source to both the meter, and neutral to 2 nd meter, Neutral made common at mtr end to run both the energy meter. Current observed 8. It was observed that 2 nd mter reading was moving fast, and the ratio of power consumption observed in the ratio of 1. Calculated Amps for each lamps 4. Power consumption in second meter observed fast compared to 1st, even after alter terminations from 2 nd to 1 st meter. Result are attached. This is because of high resistance in wire.
