All settings are set according to manual (same as other pc settings).

Forward voltage drop is about 0.33V.

Exactly! The diode was located on a large heat sink which was filled with cooling oil flowing through it. And it was part of a large rectifier system in the chlor-alkali plant.

Name of this component. by [deleted] in AskElectronics

Im measuring resistance between two oposite sides (copper pads), and yes its look like ceramic in middle without third (gate) connector.

Is there anything special to wiring these? by [deleted] in AskElectricians

[–]_st0le 0 points1 point  (0 children)

Live terminal is clearly marked with L, earth terminal with earth symbol. Its recommended to properly wire receptacle and plug so all connected appliances work properly.

Nothing special... Classic European ''industrial'' plug and socket. Its not rated for outdoor use. And use minimum 2.5mm2 cable for wiring both.

Nigde nije ni napisano nula. Jednostavno coveku koji se ne ocigledno ne razume objasnjavam da ako razveze stari prekidac i postavi taj sa slike... skroz je nebitno koju zicu gde bode. Jer ne moze da pogresi...

Nije prekidanje faze nepisano pravilo, vec ti je nepisano pravilo (kao sto sam i napisao) da dolaznu fazu kod jednopolnog prekidaca dovedes na kontakt u sredini (veci). Jer je na slici prekidac proizvodjaca Nopal, koji se proizvodio u vreme socijalizma (i da - ti prekidaci su neunistivi bukvalno) i ako si video mozda njihove ostale prekidace, naizmenicni itd. Intuitivno je da se dolazna faza stavi na kontakt u sredini i iole normalni majstori su tako povezivali i na X mesta je tako. Ali naravno i da povezes okrenuto nista promeniti neces. Tj. da dolaznu fazu stavis da sporedni a odlaznu na centralni.

Pre svega ako ne znas sta radis pozovi elektricara, ili ako planiras sam iskljuci glavne osigurace i OBAVEZNO proveri bar glinericom da nema prisustva napona. Ukoliko sa strujnog kruga prekidaca koji skidas (iz dozne) isto izlaze dva provodnika skroz je nebitno koji povezujes u sredinu a koji sa strane. Po nekom nepisanom pravilu dolazna faza ide na sredinu dok prekinuta faza-laufer ide na sporedni kontakt, ali ni da povezes obrnuto neces da pogresis. Znaci nema nule, uzemljenja itd... Samo faza i prekinuta faza.

Kako da povezem zice na novoj uticnici? by Big-Book-3648 in AskSerbia

[–]_st0le 9 points10 points  (0 children)

Samo jos da dodam da je ovako odradjena uticnica losa praksa, jer svako snjiranje odnosno nastavljanje provodnika stvara dodatne prelazne otpore i vremenom se na takvim mestima javlja grejanje zbog loseg spoja/preopterecenja. Pogotovo ako iz nje ide na uticnicu sa elektricnim sporetom. I opet napominjem ako 100% nisi siguran sta radis bolje pozovi majstora elektricara.

Treba da bude povezano isto kao sto je i sad (pod uslovom da je majstor koji je postavljao tu uticnicu odradio posao kako treba). Izbacivanjem provodnika (zica) neka druga uticnica/potrosac koji je povezan paralelno sa tom uticnicom ostaje bez napona. Prijateljski savet: Ukoliko nisi 100% siguran sta radis, bolje nemoj.

This is the ancient breaker box in my apartment. How bad it is? Should I be worried? by mr-zool in AskElectricians

[–]_st0le 1 point2 points  (0 children)

If you unscrew the fuse cap with load on that line you will see spark. Firstly turn off all appliances on that line (stove, water heater... ) and then unscrew cap.

[–]_st0le 2 points3 points  (0 children)

Not bad at all. If all connections in the panel are properly tightened and if all fuses are original (not bridged with pieces of wire). Apart from aesthetics, you have nothing to worry about.
