My in law's place had upgrading last year. They drew another power line to bring to the toilet for the instant heater.

yes, very old house usually dun have separate line for water heater i think, just wondering if the built-in elcb in the instant water heater helps?

In the old days... you dont pour... you put the kettle or pot into the bucket of cold water,  the water is heated up, the boiled water can still use for drink, make tea or whatever. 

This is a good idea

I will put the kettle into my MIL bathtub.

I assume still plug into the wall and switched on to heat up the water?

Maybe can also save electricity putting the toaster in the bathtub too?

Is it common? 

After that CNA video, then i know instant heater cannot connect to a 3 pin plug socket. Now then i realised at my parents old house, the instant heater was connected to a 3 pin plug, luckily never got electrocuted when using it back then. So i guess during that time, the heater was installed by an unlicense electrician.

Unless the owner rewire the whole house electrical wire, and separate one line for the water heater. But if the owner wants to install storage heater, think it is a must to have a separate line for it, even the house does not have one.

I do, but I just forgot my knowledge if this is HBD requirement for the LEW to sign. I may need to go back and check

you can use this to save some electricity...tell you MIL is 100% safe ..

won't get electrocuted

I thought all hdb come default with heater switches, at least my 24 yrs old flat came with both at the mbr n kitchen, paiseh lost touch liao very long nvr move house... wahaha!

“The plug itself supports up to 13 amps. The heater uses, let’s say 14 amps. That means the plug itself will have to work even harder to fulfil that 14 amps, but the limit for that plug is only 13 amps. It gets hot because it works even harder, and that’s why the wire burns,” he explained. 

"The regulation has always been to use a heater switch."

 

On the above, the 3-pin plug has a 13A fuse inside right?  If 14 amps run through it, wouldn't the fuse breaks and cut off the electricity at the plug? 

Just wondering.......

The way you quote, is like I say one...LOL

How come your rice cooker tripped at 4am? The rice cooker power is on?

When I examined the rice cooker, some part of it has corroded. You know when you use water to cook rice, sometimes small amount may spill out, but this went into the rice cooker electrical parts. JHE, unknown brand cooker, better not to buy.

The corrosion (with the neutral wire) could have edge towards the earth wire. Then somehow create an electrical path, and that tripped the RCCB. The rice cooker is not powered on, but a neutral wire touching an earth wire will trip the breaker.

HDB with default heater switches should be those newly built HDB. Old HDB dont think have.

So it mean for electrical applicances, even it is not powered on, it might still can tripped off the RCCB? Or even have risk to electrocuted a person?

That's the right way. Lay another set of power lines from the breaker. But that cost more, which people try to save.

So they end up tapping from the nearest wire, which may overload those wires.

The same thing happened in car electrical. People want to install power hungry amps and whatnot. The cheap way is to tap onto existing wires, which cause them to overload sometime in the future. And car burst into flames. Car electrical accident is more obvious, bcuz it runs on low voltage DC, so the same powered device use more current, which means more heat, unless the wires are upgraded.

There were talks of moving from 12Vdc to a higher 48Vdc. but till today, nothing much has changed. Higher voltage means lower current, and the wires can be thinner.

Like that maybe built in 90s and above got heater switch by default.

Just buy from Lazada Panasonic shop lor

they got arrange for installation

Next time I get Steven Chia to install. I saw in his video, he installed the Storage heater perfectly with much approval from the license eletrician.

Just wondering.......

The current leakage through the human body is way below 13A.  

ELCB prevents leakage to earth (through a human for example).  MCB should cut in when there is a overload (not necessary leakage). That 13A fuse is really the last resort when the MCB fails to trip.

There is also RCCB, which I think is newer solution to the ELCB.
