How to protect your home wiring a voltage regulator ?

Step 1 - Determine the type of protection

today there are fixed voltage regulators, installation of which is done on the house and mobile models that are able to serve one or several separate appliances.Besides stationary equipment can be three-phase or single-phase, depending on the application.Connecting with their own hands in this case has its differences: whether you connect the device to the 220, either to 380.

As a rule, in private houses and apartments will be more correct to connect the single-phase voltage regulator to a network near the electrical panel,which will protect the entire network from overloads.That is why the connection guidance will be given for single-phase stationary appliance.

Step 2 - Choose a place

installation situation is much more complicated when installing their own affairs, asIf you set the wrong body in the house, can occur in the best case, the output of the protective device of the system, not to mention the consequences of a fire.

So, to set the voltage regulator to the premises, consider the following recommendations:

• room should be dry and well ventilated, sinceone of the main causes of failure of the device is condensation inside the enclosure;
• when installing the product in a niche, make sure that the interior materials are fireproof - brick, concrete, metal or glass fiber;
• observe the air gap between the casing and the walls of the art.From all sides of the indentation should not be less than 10 cm;
• if you decide to install the voltage regulator on the wall with his hands, be sure to stand (or anchor) was able to support the weight of the body wall.

Step 3 - We make the connection to the mains

Actually independently connected to a voltage regulator in the home network is quite simple.Back of the unit terminal block located on the 5 connectors.Typically, the sequence of connecting wires as follows (from left to right): the introductory phase and zero, ground, phase and zero, reaching the load.In the photo below you can see the locations of the connectors:

All you need to choose the right cross-section of the cable for power and current, and then to make installation of their own hands, according to the scheme (for single-phase devices):

1. sure to turn off the electricity at the introductory panel to electrical works.
2. additional protection product, circuit breaker and RCD, which would prolong his life.Set automatic recommended after the counter, but before the overvoltage protection.
3. household power must necessarily have a ground loop.To make the connection without grounding prohibited from electrical considerations.
4. Install voltage regulator in the house in front of the counter is prohibited, and ensure protection to accommodate unit of electricity accounting is very difficult.It is better to make installation of their own hands as shown in the diagram above.
5. can not make a connection device as soon as you teach the codes from the cold in his house.Let electronics "depart" and all the condensate to evaporate inside, otherwise, as we have said above, the device life dramatically reduced.This may also include a ban on connecting products on the street.
6. protection, power less than 5 kW is connected directly to a wall outlet.This option is ideal for garages, country houses and cottages.Some produce cell voltage stabilizer unit separately on the computer, TV, boiler, air conditioning, generator, or a washing machine that allows you to protect only certain kind of household appliances.
7. If you need to connect the surge arrester three-phase, three-phase better buy unit to 220V and connect them wye than one at 380 volts.So you can save money not only on the purchase of a stabilizer, but also on its repair (repair single-phase device is an order of magnitude cheaper than the three-phase).
8. After wiring work, check the connection and installation, including automatic opening of the switchboard.If nothing buzzes without cracking and sparks, you've done everything correctly.
9. Do not connect the device to a higher power load.Reserve protection capacity should be between 20 to 30%.
10. Proper installation scheme is usually indicated on the product package.Primarily focused on it, but if there is no hint of the manufacturer, be sure to make the connection according to the given instructions.All popular models (from Resanta firms leader) must be connected for this technology.

Here and all installation and connection of the voltage regulator technology with their own hands.As you can see, nothing complicated, important to take into account all the requirements and recommendations.Finally I would like to note that every year you have to check the reliability of the connection wires in the terminal block and tighten the screws if necessary.
