Sir your video was so knowledgeable to me i understood what is actual use of MOV we need teacher like you 😊

[@TARIQLAB]

My pleasure

[@faisalarshid]

Very good information for learner's or beginners, Great work.

[@hadicutiepie3583]

Great idea, thanks a lot

[@azam1955]

Nice review,thanks but you should also inform in case there is short circuit after the fuse and about fuse rating etc.

[@JV-nt9bp]

Genius 👏🏻😊

Bahoot achha par fuse ki velu Ohm Watt ye kaise select kare ye bhee batadete to complete video hota. Jo ki ye main baat hai

[@zarzarel1910]

But, for example, a Led TV or a switching voltage source (for PC) do not have protections against voltage peaks? And yet, they also fail... but the fuse board for lighting and sockets in the house, what are they still useful? isn't it, too many protections "damage" the electrical circuits in the house? thank you for your simple and easy-to-apply explanations... my respect for you

[@TARIQLAB]

Alll good brands use varistors inside the LED tv or computer power supply

[@zelina364]

@@TARIQLAB then we dont need to add an alternative MOV?

[@patricknmd7383]

When I was young, i made this protect but I took 3 Mov. Beetween phase et neutre, phase et terre et phase et terre with a fuse sur la phase.

[@ali619786]

Aapne kitne watt ka fuse kis appliance/load ke liye use karna chahiye, agar wo bhi explain kiya hota to video poora ho jaata. Comments me batane ke bajaye, ho sake to ek video fuse wattage calculation ke saath banaiyyega. Aur agar possible ho to kitne volt ka mov use karna chahiye usually wo bhi bataiyega. Ghar ke aam electronic devices ke liye. Jaise mujhe koi idea nahi ki mere ghar ke electronic devices kitna high voltage jhel sakte hai, aur kitne voltage ke baad kharab ho jayenge. 275 volt ya 300 volt mov use karna hai etc Mov aur fuse ki value kitni honi chahiye ye mujhe clear nahi hua. Baaki working concept aapne perfectly samjhaya hai, ek baar me samajh me aa gaya. Very good explanation...👍

sir mere pass battery charger hai 20 ampere ka jo k mostly 240 volt pr jl jata hai uskeliay me ye plug bnana chahta hun to uske liay fuse kitne ampere ka lgega or varistor/MOV code bhi btaden suitable. iske ilawa mere 2 questions hai 1. MOV me positive negative legs ka chakkar to nhi hai? 2. MOV k jlne se fire to nhi lgegi?

[@techideas6772]

You should connect thermistor after the fuse because when thermistor is gonna overload, fuse will blow.

[@ProGamer-pr9rw]

Wait till it catches fire! You should put a high quality surge protector at the electric panel.

Fuse for what ?

[@ferdm9646]

3 pin will be ideal for this kind of setup. You haven't tested it so you can't tell wheadef it's working or not

[@TARIQLAB]

All appliances equipped with this spec MOV, sure it works, i don't have power line above 240V

[@ranjithcheruvathoor3921]

Always use three-pin plug.

[@BittuSingh-ul9dh]

kitne voltage per fuse short ho jaiyega

[@jimmyjayant8072]

Two questions:- 1. Is it the aluminium wire that must be connected at both ends of a glass fuse? Actually, I connect both ends of a fuse with soldering wire, it connects with little trial and error. 2. I did the same with a 3 pin plug of Girish company with a 07d471k mov and 10ampere fuse. Upon testing, the mov did not explode even at 300 volts ac. Why?

[@TARIQLAB]

7d471 is for 220/240v appliances. It should be in parallel with live & neutral

[@electrical8457]

Sir smps me kitna number ka mov lagana chahiye please

[@souravbhattacharyya3392]

Cartridge fuse rating?

[@repairingmyhobby]

apne varistor glat lgaya hai varistor ki dono legs plug k screw mein lgani hoti hai fuse se phelay nahi lagay gi..

[@TARIQLAB]

Phir jab ye short hoga tu fuse kesy jaky ga, wiring kharab ho sakti hai, ya jab bhi lagta hai fuse je baad lagta hai

[@faisalarshid]

Can be use for water pumps 9 to 10 ampere

[@TARIQLAB]

Yes

[@adwaitkumar]

Tariq bhai kya 14D471k aur 14D471 ek hi hai ? Ye kine ampere tak load utha sakta hai. Jaise celling fan, led tv,refrigerator har ek ka load alag hota hai amps alak lete hai.

[@TARIQLAB]

Jee aik hi hai, is ne load nahi uthana hota dono wire pe lagta hai aor jab high voltage aty hain tu ye short ho jata hai aor is se pehly fuse jal jata hai ya breaker trip ho jata hai ,ghar ki kisi bhi cheez ke saath laga sakty hai

[@adwaitkumar]

Thank you🎉

[@xtesster]

how the varistor protect the circuit from over voltage? in case if u had an over voltage, the varistor will burn but the voltage still be able to flow to the circuit

[@TARIQLAB]

If load consumption is 5A, we can use 10 or 20A varistor, when varistor shorts , 5A fuse easily burn that is before varistor

[@aabidsofi19]

is it better to send the surge to neutral or ground wire

[@HunterEddie]

Neutral

[@rajkhumar001]

Sir your video is nice sir. Am AC technician. In lg single door inverter fridge mov value written on this is 20d681s. But this part is not available in my area. So is there any alternative value can i add?

[@TARIQLAB]

That is 680v , check voltage on varistor if 220 then use 20d471
