Recently, uncle bought one cheap surge protector powerstrip from MR DIY store at RM24 something? dry.gif

But, to uncle dismay, the MOV is installed at wrong place. As the result, only one socket is protected from possible surge while the other three are not.

Some pictures below (large image):

Searching around the net for the MOV model returned:

Aside from the wrong MOV placement in the powerstrip, the MOV itself is fine for its intended purpose.
How in the world this thing qualify as surge protector when it only protect one socket out of four sockets? sweat.gif

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 sweat.gif  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
