Electrical switchboard for dacha. Assembly and installation

Including light, using electrical appliances, we do not think about how to begin electricity supply in our house. And it begins in any building, even in a small dacha building, with an electric flap.

Kinds

The switchboard is the location of the devices for recording and distributing electricity, protecting the power grid, and communication media. The installation of this complex device is a responsible business that requires special knowledge of electrical engineering. But, having basic information, you can install an electrical switchboard for the dacha on your own.

You need to start by choosing one of the two existing options for the flaps - internal (concealed installation) or overhead (outdoor installation). The first looks more aesthetically pleasing, but requires additional preparatory work. However, if it is planned to install a street electric switchboard for a summer residence on an external wall or to put a shield inside the house so that it does not come to your eyes, then it is quite possible to do with an overhead box.

Setting the base

To install an internal switchboard, you need to prepare a special niche in the wall, corresponding to its dimensions. It is clear that the thickness of the wall should be such that it can be "drowned" in it the whole device at the required depth. The overhead switchboard for a summer residence does not need such preparation, it is enough to fix it on the wall with the help of any suitable fasteners.

Scope of the shield

The ideal option would be to purchase an electric switchboard for a summer residence in the collection, and not to collect it in parts, because sometimes it is quite difficult to find all the details that would fit successfully into the shield and were securely fixed there.

When choosing the size of the switchboard, one must start from the number of protection devices and circuit breakers, and also take into account the reserve in case of connection, in the future, additional objects of electricity consumption. Everyone knows that the construction of a dacha is an endless process.

The standard switchboard for a dacha usually consists of a meter, a two-pole circuit breaker, circuit breakers for consumer groups and a residual current device.

In addition, to install the RCD and A3, you will need a DIN rail, ground bus (if there is a loop), a box for sealing the input A3, a connecting bus, connecting wires with a cross section corresponding to the load, a double-insulated cable bundle.

Installation of devices

Usually the electricity supply of the house consists of several groups: lighting, outlet, power and others. Each group must be connected through a separate protection device. Any device of high power (washing machine, air conditioning, water heater, oven, etc.) is recommended for safety reasons with a separate automatic switch.

In the conditions of giving it, it would be very prudent to install an RCD for a line of street outlets that serve to include garden tools and power tools, as well as to a bath line where there is an increased risk of electric shock. RCD - the device is expensive, so the desire of consumers to save on their installation is understandable. In a small country house, you can limit the number of protective devices or put one common RCD at the input.

Sometimes, because of a lack of space in the shield, you have to use differential automatic protection devices - AZ and UZO "in one bottle". Such combined devices are very expensive, in part and therefore not worth saving on the size of the shield.

Automation, filling the switchboard for the dacha, should be purchased only from reliable manufacturers, because the quality of these devices depends on the safety of people.
