Dear all, Thank you very much your valuable vedio to improve my knowledge and it is very useful and simple.. ❤so i request another vedio for How to select proper earth cables size For different applications ?

[@hfaArt]

Great sound, great video ❤❤

Great work bro 👏

[@myasir8129]

yes he truly deserve thumbs up

[@ahmedchowdhury1208]

🎉 the best video

[@electricallectures]

Thanks alot. Stay tuned and dont forget to subscribe plz

[@charithawickramarathne2108]

For the voltage drop calculation you should take load current which is actually drawn by the motor! Not the value used to rate your cable! Right?

[@electricallectures]

Always find the values based on rated load as it keeps u safe

[@kamranafzal6684]

Very good video

[@electricallectures]

Thanks for appreciating

[@danielteyehuago1633]

0:52 Please can you further explain the group factor as well as the number of circuit

[@taimur649]

Didnt really understand that how at the beginning of calculations and without knowing the cable size, we can assume going for 2 multicore cables (after which we obtain 388A load current)

[@electricallectures]

This is just supposition in order to calculate group factor. But if you keep foing calculation , you get a rough idea that how many per phase cables are needed to take the load. But proper way is to start by ond cable

[@samuelokoroafor4165]

anyone know what documentation or code he is getting the different tables from?

[@ianhowe1449]

The NEC (National Electrical Code) manual. I can look up the page numbers if you need em. The NEC is like 900 pages, but there are probably 20 pages you actually need to size any wire.

[@androb.]

Sir I need NEC book you have PDF copy of NEC book .​@@ianhowe1449

[@ajilmenon]

Hi..3.17.. No of circuits/phase means or phase?

[@electricallectures]

Means number of total cables for each phase

[@abhijithmurali9463]

I per cable = 194x1.25=242.5 right then how is it 238?

[@electricallectures]

Yes you are right

[@suvashkumarsarraf]

hello can you help me in cable sizing for building service

[@electricallectures]

You can follow this video step by step as per your load

[@arhamzayan-gu3li]

😊😊😊

[@electricallectures]

Thanks

[@bheemashankark3380]

From where we can get those tables or references?

[@electricallectures]

You can get the tables from cable manufacturer or you can download BS 7671 : 2008 standard pdf

[@thatsawesome2060]

I watch this up untill the first formula come out, and then i be like nahhh formula is not my cup of tea

[@electricallectures]

Some formula you must need rmto derive basic quantities

[@Pikachu-pi2px]

On which basis you have taken two multi core cable per phase?

[@electricallectures]

Just for an example to tell that how grouping factor apply

[@vivekpal5883]

Same calculation for aluminium armoured cables also.

[@electricallectures]

Yes same method but values different

[@TommasoCaraceni]

from which standards are the tables taken from?

[@electricallectures]

Tables are taken from cable manufacturers catalogue

[@balukummari6418]

Plz give all tables pdf

[@electricallectures]

You can find it in any cable manufacturer book

[@waqiuddinshish7127]

What if the insulation is TRS?

[@electricallectures]

Then another very critical factor also applies which is enclosed in thermally insulated material. In that case the factor is o.5 if the total run of cable on TRS is 300mm

[@waqiuddinshish7127]

@@electricallectures thank you!

[@irfanfarooqbhatti323]

Subtitles are very disturbing to se the theory

[@electricallectures]

Plz specify what is meant by disturbing. The calculation is clearly defined

[@mental_suicide]

@@electricallectures the guy probably left an automatic subtitle parameter opened lol

[@AhmedMohammadali-pn3ud]

not really understand , i will do more practise

[@saikrishnacherala2519]

Do you have any excel in which we can do cable sizing as per NEC

[@vivekpal5883]

?

[@electricallectures]

What sir
