Electrical installations

The power switches of the modular series consist of the framework and the mechanism itself. There are two types of modular series: German and Italian. By the German standard, the frame is divided by links, within which two switches are placed. Such modules can be installed both vertically and horizontally. The modules are more compact by the Italian standard, because they don’t share the links. But they can only be set horizontally.

If the bar is parallel, the number determines the number of points in the outlet (one, two, three and four) for a single phase power grid. These are the most common options in the accommodation and office arrangements. One phase is 220 volts. If the strokes are located by a semi-star, then the outlet is three-phase (380 volts). The number of seats is always the same. Such symbols are used in accommodations to indicate electrical connection outlets, as well as in drawings of industrial buildings and facilities where the equipment is used.

Water supply outlets: A special lid shall be installed to protect contact from water contamination. Level of protection against IP 44. The first number means the degree of protection against dust and fine particles. It’s going to be 0 to 6. 0 is not protected from dust and particles; 1 is protected from dust particles larger than 50 millimeters; 2 is protected from dust particles larger than 12 millimeters; 3 is protected from dust particles larger than 2.5 millimeters; 4 is protected from dust particles larger than 1 millimeter; 5 is very secure from dust; and 6 is completely protected from dust of different sizes. Number two. indicates the level of protection of the outlet against moisture. Maybe between 0 and 8. 0 — there is no protection against moisture; 1 — protection against vertical drops of water; 2 — protection against droplets falling at an angle of 15 degrees; 3 — protection against drops of moisture that can fall at an angle of 60 degrees; 4 — protection against spray of water; 5 — protection against jets of water; 6 — protection against high water jets; 7 — protection against short-term flooding into water; 8 — safety against long-term flooding into water. In the normal spaces, outlets with IP20 security. In bathrooms, in rooms with an IP44 security outlet pool. There are outlets with IP65 and above on the street. In the bathrooms, outlets with integrated ultrasound should be installed. Receptacles with protective curtains equipped with a protective deactivation function. The power shall be switched off automatically when a dangerous current leak is detected.
