Everyone should know basic electricity stuff..... its common sense....

[Clearnfc]

no fuse but got breaker la..

Breaker is on the socket side, not the plug. Then I just learn that that water electrocution case, no circuit breaker for the heater!!

So, never assume that there is definitely a breaker.

in a short circult if graded correctly breaker should operate.
at the mains box there every circuit should have a breaker

I'm one of those dunno one. Every time touch live wires do repair work, scared sheetless. Maybe put some classes here for learning?

Everyone is scared also. This is what multimeter and test pens are for!!

Basic safety rules, if you are doing any wiring stuff. You should always turn off the main circuit breaker. Then for safety, test the wire with multimeter or test pen to ensure no power. Then you are good to go.

one will go read up and learn abt it when they are curious or have interest in this area.. how many actually will have interest in such area like electricity cables and such?

 

[Coffeemate]

Actually school got teach lol. Just that people forget. I rem I was taught 3pin plug and earthing at least. Class had a good laugh on MCB and elcb

Yeah!! But.... that 3 person dead case.... no breaker!! I was shocked... Huh? How come no breaker. The RCCB only for utility room....

I agree is life skill since EVERYBODY uses electricity in modern society

not everyone know how to tell difference between 13A plug n 15A plug....

see the fuse lo

 

[riceboy]

I learn electricity in school teacher start with Ohms law
Only after i buy US textbook then they tell u about history of how electricity is discovered, static electricity, electrons etc.

Its failure of our schooling system. Never teach the what & why straight jump to how.

I think it is caused indirectly by poverty. Yes, there is poverty in "rich" SG.
SG Govt should task the Town Councils (especially those in charge of poor constituencies) to give FREE handyman (properly licensed) services to such poor families. To install such electrical devices.

Where the money come from to give this FREE? Ask GF for her plastic bag money.
Tell them please don't waste money forcibly giving each household a "portable refuse recycling bin".
Just for GF to show her boss LHL that she is working. We do not want this uncalled for rubbish item.

Use that money to give this electrical handyman service to poor families and save lives.

I call it basic knowledge, common sense rather than interest. ITs like basic maths....

13A plug comes with rectangular pins whereas 15A plug comes with thicker round pins. There should be voltage and current labels on the plug itself.

No, its HDB.. You read the article. There was an upgrade then RCCB was installed but only protect utility room....

Seems like u know your stuff. Can u advise me on this?

After my renovation I found out that the contractor took short cuts and pulled a wire from a single point to multiple locations. So several electrical outlets share a single point.

In my db, one of the switch controls up to 8 pts. While 3 other switches are not assigned at all.

Any electrician expert can advise what's the adverse impact for this ? Will it cause overload? and should the Reno electrician evenly distributed the points?

erm...i thought common sense is see hole, must plug it in.

My army commander told me. Got button you press, got lever you pull, that's how you strip a rifle.

13A plug comes with rectangular pins whereas 15A plug comes with thicker round pins. There should be voltage and current labels on the plug itself.

yes... but do they know what is it for? unless someone tells them, if not they will just use it like normally....

 

[ishtarsg]

In any case, if there is an earth leakage, shouldn’t the ELCB trip first? Over current MCB trip? That is the purpose of those component.

Yeah!! And then, you won't see 15A sockets in the socket unless its for aircon. Standard are always 13A sockets.
