    That opening segment with the reenactment of the family that was killed by electrocution. I remember reading it in the news. So tragic. Imagine how traumatised the daughter was when she saw her father collapsing as well. Thankfully she was smart, probably noticed something wasn't right and did not reach in to her father, otherwise she would've been electrocuted as well. I cannot imagine the feelings she went through in the moment. The trauma she's going through now. Just sad.

    @@Emsyaz So says who? The Quran is not the continuation of the Gospels or the rest of the New Testament. The Quran cannot substantiate itself according to the Bible ( the whole of Jewish writing in the Old and New Testament.) There is no reference of the seal of the prophets in the Old and New Testament. It is a writing (the Quran) meant to connect itself to the greatness of the Lord but the writing is not from God but from another source. The end of time will reveal this. It is a good thing the end of time is coming soon. The Lord Jesus will not come to smash the graves of Christians but he will come to take them away instead. It is called the Rapture or Catching away. This will be the greatest proof that God favors Christianity and not Islam. Millions or Billions of Christians will suddenly disappear. Hopefully in your lifetime and then you will know what is the truth. I pray you will have conviction and will put your faith in Jesus Christ on that day.

    For electrical installation of water heater, there are at least conditions to consider: 1. Minimum standards for installation of both storage and non-storage heaters to be well communicated to water heater vendors and their contractors. 2. Qualified electricians to do the installation. Requiring a qualified electrician for every installation, while still highly recommended, may not be the most practical measure, given their availability and costs. As many of the shop contractors specialize in such installation and are almost doing it everyday, they are in a position to comply if the minimum standards are clearly communicated with penalties for non-compliance laid out. Surely something can and must be done to reduce the number of death by electrocution from water heaters.

    Usually the small wall installed water heater also has its own safety electrical circuit called a ELCB ( Electric Leakage Circuit Breaker) that comes with a small test button on the water heater itself. The person using the water heater from time to time must check that this circuit breaker is working by first switching on the power and then pressing that small button to trip (stop) the electricity supply to the heater. This is an additional safety circuit on top of the RCCB ( Residual Current Circuit Breaker) found in the main electrical board/box of the house or apartment which must also be tested on a regular basis to make sure it is working.

    There are errors being presented as facts. Storage water heater has protection against overheating so pressure buildup is not due to this. 2 DP switches for the storage heater does not equate 2 energy source buildup to cause the fire. Pressure relief valve need to test for functionality and not just to ensure drain pipe is not plugged. LEW test for earth bonding, resistivity value of more than 1Ω and LEW claimed it is too high which is incorrect assumption without calculating the impedance. Steve your heater wiring of 1.5mm² may not be undersized ask your LEW to check against the conductor table in SS638. Please check against the correct table. Mr Wang stated water heater draws a current of 14 to 20A. He needs to clarify that he is referring to storage heater and not single point instant heater, subsequent images show man showering using instant heater. The cable used to demo it heating up, he neglect to state cable is undersized.

A few years ago, my parents wanted to install electric water heater because they're old and taking cold water bath makes them feel uncomfortable and boiling water in the stove just to take a bath is cumbersome. I opposed that and recommended a gas water heater because electric water heater will need a lot of maintenance, I'm glad I said that. Now, time to check my water heater, jeebus.

I don't even trust electricians as not everyone of them takes pride in their job. I wired my own home and everything is a bit of overkilled. Here they suggest the wire size for water circuit is 2.5mm² which is acceptable given that th water heater requires less than 20A but I wire mine with 6mm² which can handle up to 40A current. 😅

    using lower gauge/thinner cables is how some electrician save money. i've seen it done to a heated food display unit. the wire from the mains went into a splitter to make sure the wires dont contact each other. but the wires from the splitter to the thermostat and wires joined to the heating elements cables are of 2 sizes too small. as a result, they lasted a week before melting their insulation. having two switches to a single water heater doesnt mean the heater gets double the power. it can draw more current if there's a fault in the heater/wiring. the wife was faster thinking in that case to switch the circuit breaker off. in a fire, switch off the power and gas. you smell gas, shut off any flame and mains power. there's a reason why there's a breaker under your electricity meter outside of apartment. here's another thing to take note of, older HDBs have thinner cables, the circuits design is 15Amps while current new homes is 20Amps and 25-30 amps for high power devices(AC units/ovens/fridges). if you are moving into a 30-40yr old HDB. check the home wiring, either from prev owners or getting an electrician. my current home is 40yrs old, turning on circular Fluorescent lights causes brownout due to how old the circuits are and it has caused my desktop PC to crash.

    My old house meanwhile is probably 1 of the minority with a 15A power point in the laundry yard (so the pins are circular instead of rectangular) for older washing machines, but newer ones draw 13A instead & thus use the more common rectangular 3-pin plug (BS1363). So when my family changed to a newer washing machine, we had to change to a 15A plug too

    Hi Steven, I recently received a letter from HDB informing about plans to upgrade flats with older electrical systems to those with RCCBs. This was due to the case where a family of 3 were electrocuted from an incorrectly wired water heater. I went back to read the judges verdict and was surprised that the flat had already been upgraded with an RCCB during the HUP to add a utility room in the kitchen. Unfortunately, the RCCB only served the utility room. Although not clear, the report seemed imply that the electrician had only routed wires from the RCCB protected circuit to the utility room, essentially creating a distribution box with a dual electrical system. This was in 2003 after RCCBs were mandated in all new HDB flats. I am not sure if the EMA has electrical codes requiring newly installed RCCB must cover the entire electrical system rather than just a single circuit, so cannot comment if any rule was broken by the electrician. I wrote to EMA to enquire about the possibiliy of my home electrical system being upgraded as my home is fitted with an ELCB which predates the RCCB, and wanted to know if we would be included in this upgrading programme. Sadly, I was informed that we were not included as the RCCB is merely a renamed ELCB. EMA is not completely wrong of course because the original ELCB, which is a voltage sensing device that detects voltage leakage through the ground wire, whereas the RCCB, which was first called the current-operated ELCB was renamed to prevent confusion amongst electricians. However they differ drastically in operation and should not be confused with each other. Whilst RCCBs can detect any leakage in current (either through a short circuit in groung wiring or an alternative ground return such as through an object or person during an electrocution) the ELCB is severly limited to just leakage through the ground wire (which modern appliances tend to lack). Perhaps Talking Point could explore this topic further in your next episode? It is likely that a larger percentage of homes are currently installed with less protective ELCBs than RCCBs.

    My question is this. I've always wondered what's the point of a Fuse in the 3 pin plug? Fuses generally are meant to prevent this kind of things no ? Once current draw exceeds 13amps , it's supposed to break internally , severing the connection and preventing a short . In this scenario , the wires already fused and connected to each other and STILL the fuse did not do anything when it is supposed to when the current draw exceeded 13amps.

    I believe those 3 pin installs purposefully bypass the fuses, water heaters will to draw more than 13A so the standard usage would have already cause trips. Additionally it is likely RCCB was also bypassed for the first case as electrocution by leakage didn't trip the breaker causing subsequent electrocution.

It is melting cause it can't hold 13A load so it is "breaking" before the fuse.

    In some cases, there are electricians that would just wound copper wires where the fuse should be. This bypasses the safety features of the fuse. In some cases, the wires were under-gauged, being unable to even carry 13 amps in the first place. So wires giving up (burning) before the fuse gave way. (you can see this in the check the electrician in the video did with the ohm-meter, and got the resistance reading) I've done solar work as a hobby, I have an EE background, but for serious work, I'd still bring in a license electrician any day, pays to be safe. In some cases, an unlicensed electricians could also invalidate your insurance policy, so makes sense to get a proper electrician and plumber to sort your devices out. Stay safe folks.

    3:48 I would expect either the fuse or breaker to trip if enough current was leaking to make the earth wire live; I wonder if the earth connection itself was a bit weak. Maybe a ribbon-style cord would be less prone to this kind of leakage, since the wires would be running parallel instead of twisted together. One other thing that has compromised earth connections in recent years has been the use of plastic piping. With metal piping and fixtures, nearly all the plumbing had its own connection to the earth despite any wiring shortcomings, but now the that path would be intermittent, depending on whether the plastic pipes are full at the time. The metal water main in my father's house was replaced with plastic a while back and the installers just left the earth clamp hanging, effectively de-grounding the wiring of the whole house. It was only when I went to sell the place, after my father had died, that I noticed this condition and installed a grounding rod to restore the connection to the earth.

    Water heater sellers usually include installation as a package. When they suppressed contractors labor charges, there's where things go wrong.. Wire size and required water piping will be skimmed off to cover cost. If the resident can find their own qualified contractors, whatever charges imposed is nothing when safety and long term solutions is in question. Installation is less than 5% of the heater purchased and customers usually pay up. As mentioned in the video, qualified contractors are not easily available or their schedule is too packed to entertain immediate attention. Better yet. shop owners must bundled all the wires, piping and circuit diagrams for proper installation. For my personal instant unit, my RCD is one foot away from the heater. The heater unit itself (consumers must know) also has a CB but the additional RCD is rated at 3mA. Lastly, don't buy metal cased instant heaters, metal shrouded flexible hose and metal shower units. to reduce electrocution risk. Children are prone to splash the unit with water during bathing time. Plastic casing is best.

    Permanent high current installations should be directly wired. If the plug is loose in the socket, or corroded, it will heat up, even at lower currents. The fuse offers no protection against this. Nor does it protect against loose wires nor any bad contact -- that will overheat and cause fire. All connections should be inspected, and the loop tested for low resistance or checked under load with an infrared camera to verify there is nothing overheating.
