How to Calculate the Circuit Breaker Size ? | Breaker Sizing and Selection

[@saddamhossain3504]

Thank you sir, you have explained very well, I can gain a lot of knowledge by watching the whole video

[@pallavikhobragade1255]

Too much informative.

[@shehkhan8167]

Great Video sir.. please upload video on voltage drop calculation and Selection of No. of cable runs

[@mohameddeik9556]

thank you sir,also apload cable sizing and selection

[@DucharKotha]

Clear explanation, good ❤👍

[@danielteyehuago1633]

Please can you refer me to your video on home to select cable size for a motor...

[@samuelayele4988]

Thank you so much

[@tariquekhan9418]

Nice explanation..... 👍

[@danielteyehuago1633]

Very informative, thanks for sharing it with us...dl

Dead load we to calculate or not while selecting breaker

[@oroknowledge2232]

wich cb is recommended for 40KVA diesel generator using 3phase

[@medhanieeyob9320]

Sir nice video,i have a question. Does the total sum of amper of outgoing circuit breaker must equal to the main circuit breaker àmper?thanks

[@tkvainqueur6451]

Good job and well explained.

[@oserebright6505]

Real power/apparent power

[@vibinvarghese7660]

Usefull❤

[@surajsuryawanshi3466]

Sir this tp 100mccb selected in it each phase will carry 100A or 100/3

[@shanmukhfansclub]

100A full load current and it will divided 100/3A for each phase

[@itsok2902]

What about utilization factor u must consider

[@JC-xc8rx]

8:11

[@mungulenimarlon7573]

You are the best

[@syedzubair4885]

Sir here u considered power factor 0.8 but I want to know onething if my power factor is 0.98 after correction can i consider 0.98 power factor for it. And one more thing if my connected load is 25kw but demand load for the same connected load is 20kw so for breaker sizing which load I should take to size the breaker.

[@anilkamboj9779]

Good

[@PramodKumar-zl4gq]

Very nice

[@harip9159]

PLEASE SHOW THE BOOKS TO REFER THE SIZING OF MCB&SF UNITS USED IN PANELS

[@hasanhadi1803]

How to determine the load 2+40+... =76 right? How to calculate that

[@injumable]

What about DC Breaker?

[@MUKUNUMBIJOVAN]

👍

[@injumable]

How to calculate power factor?

[@nyinyikyaw]

nice

[@haribaskar3231]

Please 1.25 what value clear explain.

[@mulawbelay9736]

I like your lecturer but you jammed some steps you didn’t show how you find the voltage 415?

[@Qunle1]

A three phase is usually rated 415v as its standard...

[@manzoorahmad9932]

Kindly please Clear me on 1.25 Value how Calculated

[@abz831]

(Eg:-20A)
Adding 25% means of 0.25 of 20A= 5A,
then add the 5A on 20A = 25A
(Or)
(20*1=20 , 0.25*20) any number multiply to 1is that number. So 1.25

[@gulamhussain5648]

Wow !

[@sojithks4728]

👍🏻❤

[@techanicaltalks7055]

the safety factor is not 25% this is 125% =1.25

[@anasalsubaie8571]

Wrong approach:
Calculate the FLC for single motors shall be separate and not to combine with 3-phase motors

[@mohameddeik9556]

allso i need cable sizing
