The composition of the electrical panel to install on the street
What should be in street opening shield Typically, the input voltage 220V or 380V, if you agreed and received permission to use the three phases. A couple of groups of machines, counter and heating device. It is possible here to tell the long term electric, but the thrust of the article is not on super electrician, and for entry level to normal so to speak Housewives and for this we are going to describe everything as written in cooking recipes. Water fill toggle switch in order to cut off all and even the metering device to dismantle. Further, the metering device and the layout of machines in groups. From the box goes in the corrugated hose bundle of wires to different objects on the plot or house. It is important to choose for each group just under the load of the machines. Specialists and primary input put the machine. Of course you realize the introductory box, but in the first case is much more compact and practical. As machines you can use and traffic (but it is already the last century), at this time all the easier. Bet DIN rail to put her machines type UM-1X-UHLS (GOST R 5034-99) and do not forget to choose automatic current cut-off. They have to 25A or 16A or 40A. The metering device is the disconnection between the pad and the machines into groups, you can make an intermediate lamella, but it does not need the extra transient contacts are always more harm than good. Phase slashem on all inputs machines, and let the earth separately, that is all the wisdom of the wiring inside the introductory panel of power for a home or land. If you need heating, typically in the box put the bulb holder and bulb through the switch and if the cold, the lamp is kept in the engaged position.
Counters can be enabled both on a straight line if the current 100A or a current transformer, if more. The counters are written on what current they are designed, if included without current transformers. It is worth remembering that if you put the transformers, the index counter will need to be multiplied by a factor. And the box itself will be more than a third, from the case without the use of current transformers.
That is actually the most basic set of devices that can be put in the opening of the Cabinet. So if you develop this area and if introductory Cabinet in a dry heated room, you can diversify electronic stuffing. You can put the relay from the loss of a phase, if you enter three phases. You can install powerful unit stabilize the input voltage, if dad is an electrician and you have walking much voltage. If everything is somewhere on the street, it is damp and put the electronics in a box is not recommended. If you pitch heated there on a permanent basis, and then we can try, in other cases, the electronics on the street only put in sealed cabinets. How to implement heated in cabinets You can put a basic thermostat and tie its inclusion from the electronic thermometer. In this case, if the temperature in the introductory box falls below critical, the circuit is closed and is heated. The system will consume a lot of provided that you shield induction is well insulated from the external environment.
the shield can be grounded, and you can zonolite. As you wish. Put a separate block and NN touches the earth wire and the wire from the body of the drawer PE and N. the grounded shield as well advanced. Is the contour of the ground and from it to the shield pull copper wire with a diameter of more introductory. But such a practice already in enterprises, homes in the country or in the apartment is not required, just a single vanishing.
And probably most important, but little related to the electrical! Should this introductory shield to have a special filling of the hole. The shield is closed, all of the machines are visible through the cover, all the releases are derived, and the box is sealed and closed. Do this so you do not fall into the inner space and not trying to take away energy by the metering device.
