Cant agree with you more. Recently while installing a simple water filter next to my washing machine, I received a mild electric shock* when my elbow accidentally touched the side panel of the washing machine. When tested with a Philip test pen on the metal drum n metal door hinges of the washer, to my horror, the pen lit up! I suspected during house renovation more than 15 years ago an inexperienced electrical contractor worker must have wired the wires wrongly. My suspicion was proven right when I checked it with a power outlet/socket tester (see pic below). It showed that there was no Earth! 😅 After dismantling the wall socket, I found out that the PVC insulation of Earth cable was not peeled off enough and the tightening screw was actually screwing onto the PVC insulation only instead of on the copper wire! Imagine if there had been a short circuit during the 15+ odd years, you guys wouldn’t be hearing this from me already unless…. 😂😂😂

*Talking about mild electric shock, I had also experienced the same with my MacBook but I had already check the power outlet it’s connected to and the L, N and E were in order. Wonder what could be the reason…🤔

OMG!!! 🤦‍♂️

In fact, I had gone to the length of checking all my house power outlets with the outlet tester to make sure that they were wired properly. I don’t know how I could have missed the power outlet of the washer despite being so meticulous! 😂 I had also labeled all the outlets to avoid overloading any particular circuit but in spite of that, recently a 3-pin plug and the wall socket melted! It must have happened over years. Good thing the ELCB had tripped eventually else… The mistake was in connecting a 2400W kettle and a fridge in parallel in the same circuit AND most probably the use of a 3-core flexible cable which was lower than the required rating. Notice that the PVC insulation of the Live wire inside the plug and parts of the plug melted.

Normally I do not pay much attention to whether a product has SIRIM sticker or not. Now I know better! 😅

Yeah, usually if I were buying 3-pin plug, socket or switches, i would go for MK or Schneider-Clipsal. This burnt plug was happened to be on hand when I needed one and I didn’t think much of it. Most likely it came with another product I bought earlier but which had went kaput.

Bro, you have misunderstood me. What I meant was, I didn’t take SIRIM’s approval seriously. In order words, I didn’t care whether a product was SIRIM approved or not.

Never crossed my mind that the fuse in the plug top could be the weak link. Learn something! 👍

All your high current extension sockets have the plug fuse bypassed? Wow, very brave of you! What happens if your MCB fails to trip cos MCBs do fail sometimes.

Wirebrush the socket pins? I wonder how many people care enough to do that. I certainly don’t. Never thought of doing it in fact although I have wirebrushes! 😂

MCB or RCCB at the wall socket? I’m curious to learn how you do it. Mind share a picture of it? TIA

Oh this is the extension you meant. I believe I’ve seen it used by electrical contractor during my house renovation many years ago. I didn’t pay much attention to it then.

To wirebrush the metal parts of all the plug tops and wall sockets around the house will require crazy amount of work! 😅Instead, I think I’ll just wirebrush (with cordless drill) only the plug tops only of those power-hungry appliances and maybe smear a thin coat of Vaseline on them after that. 😀

These are actually what I want but the prices...

Actually, I'm capable of making the wooden extension myself. It's true. The one we make ourselves, if using all quality parts, will be much better and safer than the ready made one sold in the shops. What I'm looking for is a wall socket with RCD and not an extension.

This MK Electric 2 Gang RCD Socket will be nice to have. Having said that, I think it's not really necessary if RCDs are already installed at the DB box, unless like you, the fuse in the plug tops are bypassed. Furthermore, if possible, to inspect the plug tops, maybe once a year, to make sure that they are not oxidized.

How I wish this MK RCD (aka GFCI) socket costs a few dollars more than the normal MK socket! It’s more than 700 bucks! 😅

I actually have one of that but it’s more of a tester than a wall socket. Don’t know if PDL makes one like MK’s 2 gang one.

Agree with you.

I just have a rccb at my DB box. It’s made by ABB, model: FH202 AC, same as this:
https://s.lazada.com.my/s.3Sv4X
Specs: https://new.abb.com/products/2CSF202006R125...h202-ac-25-0-03

So it’ll be tripped at 30mA, the Rated Residual Current, correct?

The more I know about my home electrical circuit the more angry I become with the electrical contractor who did my house wiring! After grouping the various power outlets in my house into their respective circuits, I just discovered that my two washing machines, one dryer and one water heater, in addition to four other power outlets were actually all connected together to a same 20A circuit! I’m surprised that they had never tripped the 20A ELCB all these years! 😅😅😅

I think so. That means my rccb will only trip when the residual current is 100mA? If so, that’s bad news! 😔 I may have to change to one that’s rated at 63A, 30mA to be on the safe side.


Sharp eye you have! I didn’t check carefully…🤦‍♂️ TQ
