Before you go to touch any low voltage electrical system, first things you must always remind ourselves, Prije nego što idete na dodir bilo kojeg niskonaponske elektro sustav, prvo što morate uvijek podsjećati sebe, “SAFETY FIRST” is our most concerned matter. "Sigurnost na prvom mjestu" je naše najvažnije pitanje. Why? Zašto? It simply that you don’t want any unhappy things like the following happens on us. Bilo da se jednostavno ne želite bilo kakve stvari kao nesretan sljedeće dogodi na nas. It’s not just money matter but your body and life are irreplaceable and very precious than gold. To nije samo pitanje novca nego svoje tijelo i život nezamjenjiva i vrlo dragocjen od zlata. Furthermore, you are the pillar of our family who need you so much. Nadalje, ti su stup naše obitelji kojima je potrebna vam toliko. Everyday, they want see you go back in whole piece. Everyday, žele vidjeti da se vratite u cijelosti komad.

You may find the main reasons of electrical safety concern are mentioned as below:- Vi svibanj pronaći glavnih razloga električne sigurnost zabrinutost se spominje kao ispod: --

i) i) LIFE IN DANGER - we must avoid any electric shock which make us uncomfortable whole day. ŽIVOT u opasnosti - mi moramo izbjegli električni šok koji nas čine neudoban cijeli dan. More seriously, it may bring fatality with direct contact on exceeding 30mA current when time prolongs. Ozbiljnije, on svibanj dovesti fatalnost uz direktan kontakt na prekoračenje 30mA sadašnje vrijeme kada se produžava.

Basic Solution: use Residual Current Device (RCD) to cut off the current leakage promptly. Osnovni Rješenje: korištenje zaostalih Current Device (RCD) da iskorijeni trenutni curenje promptno.

In the market, you can search many forms of RCDs as displayed as above. Na tržištu, možete pretraživati mnoge oblike RCDs kao prikazan kao iznad. The useful data is as follows: Korisne podatke je kako slijedi:

1) In : 40 Amperes (Normal current), 1) U: 40 Amperes (Normal struja),

2) I∆n : 0.03A or 30mA (Operating current), 2) IΔn: 0.03A ili 30mA (Operativni struja),

3) Un : 240V~ (System Voltage), 3) Ne: 240V ~ (System Voltage),

4) 50Hz (System frequency). 50Hz (System frequency).

5) 2 poles ( two upper terminals & two lower terminals) 2 motke (dva gornja i dva niža terminala terminali)

Now, we will move to the next safety reason:- Sada ćemo se pomaknuti na sljedeći sigurnosnih razloga: --

ii) ii) PROPERTY DAMAGES - we must prevent any fire on the building and equipment which cause from overheating. IMOVINE ŠTETE - mi moramo spriječiti bilo kakvo požar na zgradi i opreme koji uzrokuju od pregrijavanja.

Basic Solution: use Circuit Breaker (CB) to isolate the overcurrent effectively. Osnovni Rješenje: koristite prekidač (CB) izolirati od overcurrent učinkovito.

1) In : 60 Amperes (Normal current), 1) U: 60 Amperes (Normal struja),

2) Un : 415V~ (System Voltage), 2) Ne: 415V ~ (System Voltage),

3) 50Hz (System frequency). 50Hz (System frequency).

4) 3 poles ( three upper terminals & three lower terminals) 3 motke (tri gornje terminala i tri niža terminali)

iii) iii) LOSS OF PRODUCTION – we must avoid the nuisance trip on the electric machines to ensure continuous operation without disturbance. GUBITAK proizvodnje - mi moramo izbjeći smetnju putovanje na električnih strojeva kako bi osigurala kontinuirani rad bez ometanja.

Basic Solution: select the proper rating and setting of Circuit Breaker or RCD. Osnovni Rješenje: odaberite pravilan rating i postavljanje prekidač ili RCD.

All electrical equipments are manufactured and governed in compliance to the local legislation and electrical ordinance which make sure all manufacturers meet their standard. Sva električna oprema i upravljali su proizvedeni u skladu s lokalnim zakonima i električne propis koji pobrinite svi njihovi proizvođači zadovoljavaju standard.

The selection of RCD and CB will be discussed in detail later on. Odabir i CB RCD će biti detaljno objašnjeno kasnije.
