apa MOV MOV ni? ELI5 takda ka?

Look carefully. It's the same.

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.

Dude, English please ELI5

Except electricity doesn't work that way. It will always travel along the path of least resistance. What the MOV does is to give it an easy alternative so the MOV burns up instead of your load. So essentially electricity doesn't really care whether it is 'nearer' or 'further' UNLESS there is added impedance which I don't believe to be the case because your power switch is barely 1' long...

Try taking a multimeter and measure the resistance between your proposed location and the actual location. Probably u get less than 50ohms. When the surge comes in at 1,000 volt, it probably isn't going to care about the 50ohms haha.

lol. TS oh TS

Now that is something new......
If that the case, why do those high end surge protector MOVs normally located before the socket or load?

Even the protection voltage also wrong.
Should be 275

Anyway, when 1000V comes along, do you think that small MOV will help?

Industrial surge protection cost thousands of dollars. And most of all, they have good grounding (which also cost thousands to achieve).

RM24 expect belkin RM90

Well the truth about surge protection is electrical surges are kinda unpredictable in terms of amplitude (peak to peak volt) or duration (surge time) so designing a perfect surge arrestor is close to impossible. Even industrial surge protector guys such as Emerson etc usually do not offer any sort of guarantee.

In fact some manufacturers put multiple MOVs across the same system in hopes that one of them 'catches' the strike. Theoretically installing a MOV at the 'entrance' is a good industry practice but there is no concrete proof that installing elsewhere along the PCC (Point of common coupling) affects the efficiency of the surge arrestor system.

If you have an expensive equipment, investing in a proper surge arrestor instead of Mr DIY is highly recommended

pls dont tell me u r an electrical engineer

we get single phase 220, 240v is rms value. peak is 220 X root(2).

275V hancur lor

What do u expect? A few hundred ringgit quality when u just buy it for few bucks? Simple terms. U get what u pay for.

you can say its electrical energy in Joule. its one of the specs.

it can many-many volts.

it depends on how much electrical energy absorbed in Joule

it will work

but not a good design

lel these cheapo thing got surge protector? jew so gullible to believe them?

betul la use 471

if that MOV is not imitation, it can offer surge protection across Live n Neutral as per spec.
