It's from Mr DIY. So, if you think it is placed wrong, DIY it.

QUOTE(lawrencesha @ Aug 13 2018, 08:03 PM) Uncle must have failed electronics in college. The MOV is placed in the COMMON ground and neutral point - which is exactly the same as what you mentioned in the later post. Anyway the thinny-tiny MOV wont help with a real surge...

Nothing 's wrong for SIRIM to approve this product. It meets the spec on what it is intended for.
Varistor is small power and protect the basic L and N line. Probably cost no more than RM5. So, I consider the power strip is not worth that RM24

Not a big fond of this surge regulator stuff on almost every damn power strips in the market. I connect power amp for audio on power strip. Depending on audio, current draw can go extremely high in a short time.

Speaking of SIRIM, the real certified Surge Protector/Extension cords get a sticker on the plug and on the extension body?

QUOTE(JohnLai @ Aug 13 2018, 07:56 PM) Yes, I know about those three lines protection. In MR DIY powerstrip, if there is power surge and all four switches are turned on, only Green socket will be protected from surge while the Blue, Orange and Red sockets will be hit by surge. In this case, the MOV should be installed as shown below in red line (Point of entry):  This way, all four sockets will be protected from surge coming from Live wire by redirecting surge to Neutral wire out. I have no idea why the MOV is installed that way protecting only one socket and still pass SIRIM. stop making accusation if i am the socket manufacturer i can send LOD to u, the 3 line straight connect to all socket the MOV put every where also same effect if it is connected after the switch then this MOV are only protect the particular socket , but this photo clearly show the MOV connected to the main line before the switch. u try plug in and power on but dun switch on any of the socket use test pen to test the place of MOV connect it is live , means the MOV are protect the whole gang of socket. It is just place at the end of the main line This post has been edited by bereev: Aug 14 2018, 08:46 AM |

I can feel my table fan rotation suddenly speeds up a lot before returning to normal speed after my neighbours shut down their equipments. Cannot complain to TNB and let them tackle this? |
