Power factor is not typically considered when calculating the current for a single-phase load in designing a Miniature Circuit Breaker (MCB) for several reasons: Simplification: MCBs are primarily designed to protect against overcurrents and short circuits. Considering power factor would add complexity to the design calculations without significant benefits for single-phase loads. Unity Power Factor: Many single-phase loads, such as resistive heaters and lighting, have a power factor close to 1 (unity power factor). In these cases, the apparent power (VA) is approximately equal to the real power (Watts). Therefore, using the current based on the real power simplifies calculations. Limited Impact: For most residential and small commercial applications, the impact of power factor on the current is not significant enough to warrant special consideration when selecting an MCB. Focus on Overcurrent Protection: MCBs are primarily intended to protect against excessive current that can lead to overheating and fires. Their main purpose is to disconnect the circuit when the current exceeds a safe threshold, regardless of the power factor. However, in industrial or commercial settings where power factor correction is important, and where non-linear loads like motors and electronic equipment are common, power factor may play a role in electrical system design and protection. In such cases, other protective devices or specialized equipment might be used to address power factor issues.
But sir isme motor ke liye select karu to usme inrush current calculat krna padega to motor ke liye ye inrush current extra humko dhyan me rakh ke select krna padega na ....ya firr 25% jo extra leke chalte he wo iske liye inough he??
Pls sir 1.5 ton 5 star inverter ac ke liye konsi mcb le mene kitne logo ko pucha sab alag alag bttate hai koi c 16 Amp koi c 25 bolt hai kyuki saruaat me load jydaa hota. Hai bad me Kum hota hai .. aesa bolte hai to pls help me..
Rccb 32 amp aur MCB 40 changeover ghar ke liye sahi hai Please reply urjent Use- मोटर, वाशिंग मशीन,फ्रिज,प्रेस, (5 फैन 50 से 70 वाट का) लाइट बल्ब led Rccb32 एम्पियर सही है और Mcb40 एम्पियर changeover सही Thanks waiting for reply
If we use 6AMP MCB and as per your calculations load current is 4.5AMP . Now if current flow through load is 5.5 amp. Then equipment may damaged and MCB will not trip ...is it correct?
Sir agar kitchen mai fridge hoga, induction cooktop hoga.,rice cooker hoga aur 2 led bulb aur eak wall fan hoga to kitchen ke leye kon si ampere ki mcb lagani hogi aur wire kon si lagani hogi.....bathroom mai agr geyser hoga..washing machine hogi aur eak led bulb hoga to kon si ampere ki mcb lagani hogi aur kon si mm ki lagani hogi.. Aur sir 3 rooms mai agr 2...2...bulbs eak wall fan aur eak socket hoga jis mai winter ko blower lagana hai. To in 3 rooms ke leye kon si mcb lagani hai..aur wire kon si mm ki lagani hai.. To sir is poore load ke hisaab se main double pole mcb aur rccb kitni ampere ka lagana hoga.. Aur sir is load ke hisaab se service line kitni mm ki hogi aur double pole mcb se rccb tk aur rccb se single pole mcb tk kitni mm ki wire hogi.. Is load ke hisaab se kit kat fuse kitni ampere ka hoga aur changeover kon sa lagana hai.. Sir app ka ki bhtt meherbani hogi mje is comment ka answer dedo.. Yaa to is poore topic pr eak video banalo is load ke hisab se thank you sir.. Hamari voltage 220 ki hai
Sir if in my whole house i have 1 fridge 1 induction cooktop 1 rice cooker 1 blower 1 geyser 1 clothing iron 15 led bulbs 6 wall fans so according to this load which double pole mcb and rccb i have to install in home.. We have 220 voltage..my question is which type of mcb and rccb in ampere according to this load plzzzz sir it will be your most kindness if you give a answer honestly...
Meta ak BASIC sa questions hain sir alternating current main hum neutral se shock ku nehi khate? Or Agar 2terminal pe voltage dfrnc same ho toh Kay current flow kar sakta hain..? Koi vi possibility hain?
Very informative 😊
सर , घर का load calculation निकालने के लिये power factor add करना चाहिए क्या नही ?
0.9 power factor add kar sakte ho Ghar ke ander
Thank you so much sir 🙏 Video
Have a nice day sir
B, C, D curve pe bhi Bana dijiye apki video bahut useful hai thanku you for making such videos..
🙏 GM Sir, u having shared good information about MCB selection. Thanks 👍

1st Comment nice sir thanks
Sir aik video mein ap ny current nikaalny k lia voltage or root3 ko multiple kia hai p.f nhi lagaya...
Single room ke liye 32amp ki MCB lagayI hai koi problem to nhi
B,C,D per bhi bana do
thank u sir
Bhai aap bhut pyara padhate ho
But sir isme motor ke liye select karu to usme inrush current calculat krna padega to motor ke liye ye inrush current extra humko dhyan me rakh ke select krna padega na ....ya firr 25% jo extra leke chalte he wo iske liye inough he??
Thank you knowledge
Thanks bro ur awesome 🙏
Pls sir 1.5 ton 5 star inverter ac ke liye konsi mcb le mene kitne logo ko pucha sab alag alag bttate hai koi c 16 Amp koi c 25 bolt hai kyuki saruaat me load jydaa hota. Hai bad me Kum hota hai .. aesa bolte hai to pls help me..
Very nice sir
Good
👍👍👍
Kya isme #Power #Facter multiply hoga (P=V×I×Cos) (Watt=V×I×√3×cos)
kya ye formula right h
Yes, u have consider the power factor.
Rccb 32 amp aur MCB 40 changeover ghar ke liye sahi hai
Please reply urjent
Use- मोटर, वाशिंग मशीन,फ्रिज,प्रेस,
(5 फैन 50 से 70 वाट का) लाइट बल्ब led
Rccb32 एम्पियर सही है और
Mcb40 एम्पियर changeover सही
Thanks waiting for reply
Coski value nhi aayegi kya isme?
Very nice
Nice video

single phase ka matlb single wire hota hai???
Nice sir 👍
Bhai calculation kr dia kro Puri ki Puri
agarthree pole mcb 32 amps ki h to complit mcb 32A ki h ya ek pole 32 amps ka h??
Dear sir
Please ek video VFD per or bna do
sir pls video bnaiye B ,C,D, type MCB kya hota h
Bhai kya 1.5 mm wire pe 1200wt ricecooker ka load utha sakhte hai...?
A.B.C.D K.Z TYPE OF MCB PL MAKE TJE VIDEO
Sir mcb par details mai video banao
Plz give the detail video on type of MCB ie B.C or D tupe
Sir 4.5 A is load
So can I select 10 A MCB what happens
why did you neglect the power factor while calculating current??
My question is same
He should be assume pf 0.8
Sir if in my whole house i have 1 fridge 1 induction cooktop 1 rice cooker 1 blower 1 geyser 1 clothing iron 15 led bulbs 6 wall fans so according to this load which double pole mcb and rccb i have to install in home.. We have 220 voltage..my question is which type of mcb and rccb in ampere according to this load plzzzz sir it will be your most kindness if you give a answer honestly...
Current calculation me power factor aur efficiency ko include kyu nahi kiya
Hello dear, you missed 1 important point " Power Factor"
sir explained more in single phase please 🙏
👍
8kw के लोड हो तो कोनसा MCB लगाउ सर ?
bhai thanks for your video ,but where power factor"
sir this formula is for apparent power not active power, how does you get Ampere when you divide kw by V, ?
first convert the given power into kva then use this formula P = (I)(V)(POWER FACTOR) for current calculations,
❤️❤️❤️
220V&415VMA. HP. KW AMP MFD PF K LIYE. COSTAK BATAIYE. YANE KI. FORMULA
Single phase power factor nehi lage ga
B C D made this topic video bro.
मेरे आटा चक्की में 1फेस की 3hp मोटर में कौनसी mc b लगाई जाए
What will be Wire size for B type 10amp MCB.
B c d k type kya hai
Sir 1 hp me .746 watt hote hi sir ji
Power factor kidhar hein
B=32,c=32are same?
Nhi function alg hota h. Par dono overload 32 ampere he hoga..apko detail video chiye ho too comment karke jarur btaye.
Sir 100Amp MCB all so available in market
What MCB for 3kw load?
Sir why you have not multiply of pf
Hp/1.341 = kw
Sir ,
Why we took this value 1.341 ?
Why you have not multiply power factor in current find out formula
सर इस हिसाब से रीडिंग कम आ रही है ट्रिप हो जा रहा है बार बार
Meta ak BASIC sa questions hain sir alternating current main hum neutral se shock ku nehi khate?
Or
Agar 2terminal pe voltage dfrnc same ho toh Kay current flow kar sakta hain..? Koi vi possibility hain?
Nutaral ak return provide krne ka kam krta hai . Islye nutral me current and voltage 0 hota hai
1hp = 735.5 watt
3hp mein kitna empier MCB
Power fector hai gay
P.f nhi hoga
1HP=746W
P.f q ni lagaya....
In my home I have fridge, washing machine, TV, vown
Oven, which ampier MCB I have to select.
Sir transformer sop send me
What is 1.341
Galat kyu bata rhe ho sir
Smjh nhi aaya video bhut fast h
Yeh hota hai video, no bakwas sidha content.
Ur HP to KW conversion is outrightly wrong. U have confused between electrical KW and refrigeration or work done KW.
1 amp ki mcb khahape milegi sir
बहुत मजे ले रहे हो😂😂🤣😋🤣😂 स्विच भी नहीं आता 1A का तो
@@Tech_Gaurav video me bataya hai ki 1 amp ki mcb aati hai aap video me dekh ke tasalli kar sakte hai 4:28 minutes pe
Me bhi confused hun ki 1 amp ki mcb aati hai ya nahi
Thanks guru
B,C,D type ki mccb par bhi video banaye
