A Big Thanks for your magnificent job of teaching us from scrach. It often helpful to make some quality negotiation with consultant & infra individual as a "Sales Specialist".
Thanks a lot for making a video of full knowledge, easy explaination, simple method.. it helps us a lot to perform best in company and to face the interviews. Tons of thanks to you❤
Yeah much easier than engineering theories. But on Job it is a challenge to deal with complexity of projects. This was just a basic sample to make it easier for audience to understand.
Great, thank you! Can we consider socket outlet power consumtion as a common connected load? And also please share us electrical design for residential house G+3 with all connected load like kitchen, lighting, washing machine, Iron, sockets, water pumps, oven , etc. Thanks bro.
manny many thanks sir g....outstanding video.......please continue thils topic electrical designing. upload more videos related to electrical building design..l...cable selection farmula etc.etc please
I am working as a deputy messenger in a good housing society in Pakistan. I have seen your video on youtube. It is important to learn building. Tell me some main points
Awesome explained.....sir kindly make video on cable sizing, voltage drop, ssc, bus bar sizing, earthing and lighting arrester calculation for the same project.
Thank you very much for this informative video. I had one question. 2BHK flats are provided with single phase supply. So when determining C.B size, for converting Watts to Amps, we should be multiplying with 8 and not 1.9 right? (Based on your G+5 electrical design video)
thanks sir for your kind to explain us more I would like to ask you PART-4 for the C.B sizing for main meter panel and flats.at PANEL-1 How you got common load result in 60kw? thanks sir.
Thanks for the Video, Can your please explain how the Multipier Value (KW - A =x1.9 ) Comes. Where as I =P/(VxPF) for Single phase and I = P/(1.732xVXPF). Kindly Correct me if I am Doing any mistake understanding Data manipulation. Warm Regards
HI Dear, I wanted to know that why did you assume DF as 70% while for the commercial buildings you mentioned earlier standar DF is 80-90% in India. please explain this point, Thanks
Great brother..Suppose you have 2 transfer pumps,1 is standby and other is on duty, means they will work interchangeable and both will not ON at Sam time and they are in same panel MCC,..So how will you calculate main cable to this panel, will you consider kW of both motor or only 1 ?
Time 11:04 When you are calculating MCB for 2BHK load, you multiplied 5kw by 1.9 ... but wo to 3 phase ke liye aayega na ... for 1 Phase 5.43 Amp aayega na as 5 kw load is Single Phase load. Please correct me if i am wrong.
Brother you didn't count future expansion of 20-30% why? Also you considered only demand factor but not diversity factor .. And i designed further and calculated and i got secondary current more than 1200A ...so should I take 3 runs of 1core 300sq mm cable or 3 run of 3 core 300sqmm cable.?
I need urgent help. Actually I got bit confused. I have to select cable, which load I should consider while selecting cable size from transformer to MDB Should it be tcl amp or peak load amp or transformer amp or circuit breaker amp. Pls do reply as early as possible
Usually a cable between transformer and supply connection facility is provided by supply authority and is sized depending on transformer secondary side ampere setting. Supply connection facility is used by supply authority to set the current to certain required amperes depending on supply application done by electrical consultant by calculating max demand. The cable from supply connection facility is sized depending on circuit breaker setting in supply connection facility. I hope this answers your question.
Always cable +breaker is sized as per continous current of the Transformer + consider the derating factors for grouping depth of laying and Thermal withstand capacity. and also the voltage drop . all calculated precisely.
@@ElectricalInfinity can't find it in there... Is it mentioned explicitly that for a 2bhk this much capacity energy meter and so on... I have calculated loads of all flats individually but even after taking into diversity factor the load is quite large...
I have a doubt related cb sizizing For 1500kva transformer Secondary side. Once we convert kva to amp 1500kva*1.4 =2100A Should be consider 1.5 safety factor or directly select breaker from 2100A
All loads are distributed equally among each phase of 3 phase supply. Usually the loads are single phase for example lighting circuits and power loads. If it's 3 phase load then a 3 Phase supply is provided.
Sir can you tell me if load is 868KW, power factor is.0.8 and voltage is 415v and the cable length is 138meter. Which size cable we should chose to have maximum voltage drop of 3 percent

first of all thank you for the great video, But please can you explain how you decide to use 7.5 kw for 3BHK ?
wow very helpfull
Thank you so much for this. Could you please if you have time just explain the above 40-floors building details as per Indian standard.
Can you please make a video on calculation of lightning arrestor and calculation of earthing rod, pits and wire?
Thanks you so much.
Hello! I just saw your channel and I am so thrilled. J would just like to ask.. Is this as per australian standard?
Hi Franchette 👋,
Thanks for watching. Yes, the design is as per Australian standards.
Nice 👍

Sir, We need to consider hvac load
for public area and corridor's,
Firepump
But the loads you clubbed together are single-phase loads. Where as the main power supply will in three phases.
At 11:00 how did you get those MCCB values? Why is it almost doubled when you already multiplied them by 2?
Safety factor
B+P+33 including club, stp, water supply, fire system. Provide electrical load calculation.
Thanks for the Video, Can your please explain how the Multipier Value (KW - A =x1.9 ) Comes. Where as I =P/(VxPF) for Single phase and I = P/(1.732xVXPF). Kindly Correct me if I am Doing any mistake understanding Data manipulation. Warm Regards
Please make a video overall design parts such as cable calculation, voltage drop, short circuit, power factor.
Great video, thank you!! Would you make video on cable sizing considering voltage drop for high rise building.
Thanks. Will make it soon.
I think common load should be seperated and it should have Seperate SMDB
Sir give a link for , workout screen calculation...give a new video also sir
HI Dear,

Can you make a video on the cable size selection from transformer to transformer's CB and from tx's CB to load' CB?
Great brother..Suppose you have 2 transfer pumps,1 is standby and other is on duty, means they will work interchangeable and both will not ON at Sam time and they are in same panel MCC,..So how will you calculate main cable to this panel, will you consider kW of both motor or only 1 ?
Total of both.
@@ElectricalInfinity but at any instant, both will not work together, then why we consider both load ? Is it general rule to consider both ?
That's why we take 0.7 demand factor after calculating total load.
Why you take 2 time demand factor
1) for TCL and
2) for metering panel c.b selection
Please give the answer ?
Hello,
Can I convert kw to amps by .
First kw to kva
Then kva to amps.
If do like this different values coming ,what should I do?
How you find the value of 1.4 when you convert kva to amp ?
Nice explanation
But
The breaker size of 40A for 5kw load seems to be high
Also 50A breaker is not standard size
In the video, df for residential is mentioned as 0.6, but you considered 0.75, why the difference? And what are the actual standards?
Is it according to Uae standard or indian standard
How to calculate electrical meter room and duct size
This is very informative.
I am here in UAE as a fresh electrical engineer and looking for job. Can anybody help me getting a job.
Thank You
Time 11:04 When you are calculating MCB for 2BHK load, you multiplied 5kw by 1.9 ... but wo to 3 phase ke liye aayega na ... for 1 Phase 5.43 Amp aayega na as 5 kw load is Single Phase load. Please correct me if i am wrong.

Can u make video on Important is and nec standards
Will try to make one
Could you please provide links to reference guidelines?
Bro it's better to share the image of those calculations thanks 👍🏻 very useful
Noted
Sir cable size bhi bata dete
Sir please mention cable size.....in SLD...
Will do separate video for that
Where is the standard to be exact for 2bhk 5kw energy meter and 3bhk 7.5kw? I need to furnish it for a project of mine...
IS 13010
@@ElectricalInfinity thank you so much
@@ElectricalInfinity can't find it in there... Is it mentioned explicitly that for a 2bhk this much capacity energy meter and so on... I have calculated loads of all flats individually but even after taking into diversity factor the load is quite large...
@@ElectricalInfinity also if I could discuss it with you somwhere else..
It's a general thumb rule contractor follows for considering total load. Usually it's 0-10 amps, 10-20amps and 20-30 amps energy meter rating.
Circuit breaker calculations?
From where I can get the Standerd chart of Transformer , Cb e.t.c
You can get Transformer standard sizes from supply authority and cb sizes from manufacturer manuals or datasheets.
Buy TNEB Hand book.
Ipad kaun sa hai bhai btana lena hai mujhe
Bhai single phase meter kitna load leta he
please make your next video at low speed
Raw power is done ...Sir plz added ups power....
It would be great to explain this slowly. Kind of confusing and some details were not explained properly. Why did you use 400A in 9:52?
please upload video we are waiting for new video
You should explain it according to any international standard,
Time 06:17 where this 1.4, 1.9 and 1.5 came from ?
Whay about shop, if considerd?
Well we need add total load of the shop and consider demand factor as 0.8 to 0.9 for commercial places.
I have a doubt related cb sizizing
For 1500kva transformer Secondary side.
Once we convert kva to amp
1500kva*1.4 =2100A
Should be consider 1.5 safety factor or directly select breaker from 2100A
How a flat will use 3 phase???
All loads are distributed equally among each phase of 3 phase supply. Usually the loads are single phase for example lighting circuits and power loads. If it's 3 phase load then a 3 Phase supply is provided.
@@ElectricalInfinity sir, then there are SPN inside the room which are not showing here???
upto 3KW - 1PH /240V IS enough , >3kw opt for 3ph 415v.
Can i have this Sheet you write in the video please?!
IN FOUR POINT HOW WILL YOU DESIGN THE PANEL?
Bhai ye pen kaha se magbaye
Logitech
For 19 amp y we use 40 amp breaker+
Thank u , but its very fast way so
As you r trading from papers
Sir can you share the notes??
Sir can you tell me if load is 868KW, power factor is.0.8 and voltage is 415v and the cable length is 138meter.
Which size cable we should chose to have maximum voltage drop of 3 percent
Calculate VD on actual current , Not on Derated Current. Derated Current is only for cable+Equipment selection.
Where is cable sizing, voltage drop, sc calculation?
Will make another video for that. The video would have become lengthier if added everything you asked for.
@@ElectricalInfinity Thank you
Hloo bro can you share your linked in profile?
ONLY I NEED YOUR ONLY FEW TIME IF POSSIBLE I WIST YOU GIVE ME POSITIVE RESPONSE
they said three lift but write only two lifts
This video already you had made
Steps 4 and 5 are different. This one is for high rise building not g plus 5. Watch it full you will know the difference. 😊
1 KVA = 1.9 anybody explain please
in my calculation its is 1.39 something
Very interesting but your vedios is too much fast 🙈
Thanks and sorry for that. You can use reduce the speed to 0.8x while watching
Hlo
very fast explanation 🙄
really helpful amir need a small help is it possible to get in touch with you that will be your most kindness
