Illustrated practice of mounting and connecting electrical installation devices and accessories in various electrical installations – Part 1

The photos in this series are partly my and from my friends who working everyday these jobs in their practice. Many thanks to my Friends from various page and regions.

Note: Almost every photo is one short lesson without many words.

There are a large number of different electrical devices, equipments, parts, elements, accessories… such as:

– electric installation switches with and without signal lamps of different constructions and purposes for classic electrical installations,

– fuse fuses of different types from different manufacturers,

– automatic circuit breakers,

– manual low voltage switches,

– automatic switches,

– fuse-switches,

– manual switches for control circuits,

– selector-type switches,

– switches for almost any purpose,

– double, three-pole, five-pole installation and industrial sockets and plugs,

– relay,

– contactors,

– buttons with and without signal lamps for control electric circuits,

– electrical conductors and cables,

– sound and light signaling devices,

– special protection devices of the switching type,

– classical lamps,

– LED lamps,

– decorative elements and lamps for lighting and visual simulations,

– time switching and control components for each purpose,

– modern devices for home installations with remote control using

remote controls and telephones,

– micro switch,

– limit switches,

– sensors and sensor switches,

– electric and electronic measuring instruments and indicators,

– electric and electronic circuits and devices for measuring and controlling all physical, non-electrical and electrical quantities; temperature, current, voltage, overload, stress, pressure, velocity, flow, heating, all modes of movement, etc.,

We could enumerate indefinitely both by category and by name, but let’s leave that for another occasion.

I will not theorize much in this series of practical examples.

ostavimo to za neku drugu priliku.

U ovoj seriji praktičnih primera neću mnogo teoretisati.

2.  Izrada nadzidne (OG) električne instalacije.

Upotreba u ekstremnijim uslovima rada.

2. Working out of wall-mounted (OG) electrical installation.

Use in more extreme working conditions.


Slika 2.1. Vertikalno polaganje instalacionog kabla po betonskom stubu za
nadzidnu trofaznu šuko utičnicu. Kabl ili izolovani jednožilni provodnici
su uvučeni u plastičnu rebrastu instalacionu cev, koja se pomoću obujmica
pričvršćuje na stub pomoću specijalnih zavrtnjeva ili ekserima za koji se
specijalnim alatom upucavaju u beton. U praksi ovu vrstu instalacionih cevi
monteri odnosno elektroinstalateri nazivaju crevom ili bužirom.
Figure 2.1. Vertical laying of the installation cable along the concrete pillar
for the three-phase wall socket. The cable or insulated single-core
conductors are pulled into a plastic ribbed installation pipe, which is fastened
to the pole with clamps using special screws or nails for which they are
drilled into the concrete with a special tool. In practice, installers or
electricians call this type of installation pipes a hose.

Slika 2.2. Slika prikazuje montiranu trofaznu utičnicu na betonskom
stubu do koje je došla instalaciona rebrasta cev sa provodnicima.
Figure 2.2. The picture shows a mounted three-phase socket on concrete
the pole reached by the installation corrugated pipe with conductors.

Slika 2.3. Primer dovoda trofaznog napona za jednu trofaznu šuko
utičnicu montiranu na betonski stub, vazdušnim putem do stuba i po stubu
vertikalno naniže. Za zaštitu provodnika korišćena je rebrasta plastična
instalaciona cev crne boje. Kod vertikalnog polaganje instalacionih cevi ili
instalacionih kablova obavezno se za podlogu učvršćuju pomoću obujmica
na međusobnom rastojanju cca 50 – 70 cm.
Figure 2.3. Example of three-phase voltage supply for one three-phase schuko socket mounted on a concrete pillar, by air to the pillar and along the pillar vertically downwards. A black ribbed plastic installation pipe was used to protect the conductors. When laying installation pipes or installation cables vertically, they must be fastened to the base with clamps at a distance of approx. 50 – 70 cm.

Slika 2.4. Detalj montiranja jedne trofazne šuko utičnice sa zaštitnim
poklopcem na otvorenom prostoru. Provodnici su dovedeni kroz rebrastu
instalacionu cev koja je uvedena u kablovski uvodnijk sa elementima za
dihtovanje za zaštitu od prodiranja vode u istu. Po pravilu, cev se fiksira za
podlogu (ovde betonski stub) na 15 cm od uvodnika kutije, što je u ovom
slučaju i učinjeno. Cev je pričvršćena pomoću obujmice izrađene od
perforirane pocinkovane trake a pričvršćena pomoću zavrtnjeva.
Figure 2.4. Detail of mounting one three-phase schuko socket with protective cover with a lid in the open. The conductors were brought through a ribbed installation pipe which was introduced into the cable gland with sealing elements for protection against water penetration into it. As a rule, the pipe is fixed to the base (here a concrete pillar) 15 cm from the inlet of the box, which is done in this case. The pipe is fastened with a clamp made of perforated galvanized tape and fastened with screws.

Slika 2.5. Izgled pravilnog povezivanja trofazne šuko utičnice sa faznim L1,
L2, & L3, neutralnim N i zaštitnim PE provodnicima.
Figure 2.5. Appearance of correct connection of three-phase schuko socket
with phase L1, L2, & L3 conductors, neutral N and protective PE conductor.

Slika 2.6. Detalj prikaza spojeva faza L1, L2 & L3 (braon, crna, siva boja
faznih provodnika), zaštitni PE provodnik-žutozelene boje a neutralni N
provodnik plave boje. Ovde je korišćen provodnik punog preseka, a pošto
su priključnice sa zavrtnjima i specijalno oblikovanim priključnim elementim
kao se vidi na slici, na krajevima provodnika su napravljena okca. Ova okca
moraju biti okrenuta sa otvorenim delom prema desno zbog zavrtanja
steznog zavrtnja. Telo utičnice je od porcelana kao što se vidi na slici.    
Figure 2.6. Detail of L1, L2 & L3 phase connections (brown, black, gray
phase conductors), protective PE conductor yellow-green and neutral N
conductor blue. A full cross-section conductor was used here, and since the
connectors are with screws and specially shaped connecting elements as
seen in the picture, eyelets are made at the ends of the conductors. These
eyes must be turned with the open part to the right due to the tightening
of the clamping screw. The body of the socket is made of porcelain as can it
see from photo.

Slika 2.7. Na ovoj slici je prikazan instalacioni prekidač montiran na
betonskom stubu gore za električno osvetljenje a jednofazna priključnica
ispod predkidača. I za prekidač i za utičnicu su dovedena dva kabla kroz
zasebne rebraste instalacione cevi.
Figure 2.7. This figure shows the installation switch mounted on
a concrete pillar above for electric lighting and a single-phase socket under the switch. For both the switch and the socket, two cables were fed through separate ribbed installation pipes.

Slika 2.8. Slika prikazuje jednu nadzidnu elektroinstalacionu razvodnu kutiju
montiranu na betonskom stubu ispod horizontalne betonske grede. U ovu
razvodnu kutiju instalacione cevi sa provodnicima ili kablovima su
dovedene sa strana horizontalne betonske grede zgrade. Iz razvodne kutije
niz betonski stub odlaze dva električna kola, jedno za prekidač osvetljenja
a drugo za jednofaznu šuko utičnicu a što se može videti na prethodnoj
slici.
Figure 2.8. The figure shows one wall-mounted electrical installation junction box mounted on a concrete pillar under a horizontal concrete beam. In this junction box, the installation pipes with conductors or cables are brought from the sides of the horizontal concrete beam of the building. Two electrical circuits go from the junction box down the concrete pillar, one for the light switch and the other for the single-phase socket, which can be seen in the previous pictures.
