Please also include the thickness of the GI sheet i.e. the cable tray u have shown how to calculate the width, Depth and thermal expansion gaps but how do u select the thickness like the weight bearing capacity of the tray and the supports needed like the tray is supported on c-shaped channels hanging from threaded rods suspended in the ceiling or simply supported by steel channels on ground . As you done the calculation , you should also include the weight of the cable per meter multiply it with the tray length and number of runs which will give you the exact weight of the cable lying on the tray depending on the weight you have to select the thickness of the cable tray(like 1.5mm or 2mm depending on the weight bearing capacity of the GI sheet/ ladder rungs if it is ladder type/ perforated/ solid bottom ) and you also need to provide cable cleats or cable ties in order to protect the cable from shooting out of the tray in case of short circuits. Please feel free to correct me if anything wrong in it at the end no one is perfect ......ohhhh i almost forgot to mention the spare capacity in case you need to lay more cables on the existing tray for future expansion of the facility.😛😛
Bro mostly they don’t calculate for cable tray. They just calculate how much loads are going to pass through. No one gives a damm about air space. Anyhow ur video is informative. Thanks for that.
Brother your videos are Electrifying the Electrical Engineers
Lots of love from Qatar ❤
Thanks a ton
very informative and important one
Sir i have a question. Why we are not considering the thick ness of arnouring like materials apart from the conductor size to determine cable diameter
Same question , insulation material should also consider 👍👍
Sir need more flat load calculation video I am learning Revit MEP software plz provide the notes regarding this in pdf it will easy for us
Informative..! Which notepad are you using..?

It depends on contracting company. If they follow standards it is good for client as well as for company.
BTW thanks for appreciation.
can somebody explain me that why are we multiplying the no of cores with the diameter to find the final diameter of cable??
Sir could you please share/mention the reference document for this explanation
Your electrical designing is awsome. Is there seperate course from which we can learn.
I'm not able match these method with cable manufacturers catalogue.....pls could you help me on this..
Nice video keep it up.
Can you tell me before starting electrical project design calculation what should we do.
Really a helpfull video
Glad to hear that
Awesome amer bhai
Thanks! Glad you liked it.
What about for 80 percent fill or 50 percent fill in hazardous locations
Very good
Thanks
Nice bro
Thanks
Concept is good,video is going very fast please make it slow
Why the maximum air gap is 100% sir???
If the cable sizes are different then how we will calculate the space factor
consider the biggest one among two cables.
Sir why you did D=2r
Diameter
Presentation is too fast like advertise of TV diffcult to understand ✌️
Sorry for that
So much ads!!!
