- เผยแพร่เมื่อ 31 ก.ค. 2024
- This is the first video of a serious of upcoming several lessons, in which I will be going through the journey of Electrical Engineering Design principles, based mainly on the UAE regulations and standards (mainly DEWA).
In this video, you will understand what does a 3 phase distribution board load schedule represent, what does it consist of, and what does it relate to when it comes to the actual electrical panel representation of this sheet.
You will also understand the basic principles related to preparing the electrical load schedule as per DEWA standards, which will make it easier for you to understand and comprehend how to prepare a load schedule with a solid understanding of each and every relevant technical detail....so, you will be understanding instead of simply memorizing.
My overall goal is to share my Electrical engineering design experience which I have gained from working in this field for over 12 years and I will be going through the design procedure, the calculations involved, the principles behind these calculations, helping everyone who is interested in learning to thrive and succeed in their career.
If you like my videos, please give a thumbs up, SUBSCRIBE to my channel, and share the videos to whoever might be interested.
Please refer to the following address for a fully detailed explanation :

After all theses years only after watching ur video i got clear understanding of the electrical system
U r great tuitor my dear..
Really appreciate the video! I look forward to more of these videos for MDB & SMDB and other electrical based videos
Sir you are doing a great job.
Thank you very much for these videos.
Great explanation sir 👍we are waiting for more vedios
Thank you very much for the content you make. It's been a great learning experience.
Usually i dont comment on videos but Masha Allah very nicely explained i relly didnt wanted the vedio to end
Thanks for your clever explanation about the load schedule
Best explanation...please continue your work❤❤❤
Thanku sir.......... waiting for more videos this channel
It was much helpful. Please make the next part with the electrical designing concepts of load schedule and the associated.
U are wonderful lecturer sir.
Thank you very much for the well explained tutorial
Very informative video. Great job
Keep up the good work
thanks a lot for your efforts sir
God bless you
Thank you so much sir its Really easy to understand and very Knowledgeable 😊
Very nicely explained 👏 👌
thank you so much.. nice.. Waiting for next video which explains how to make a load shedule from drawing
Helpful content
Good explanation 👍🤝😍
Assalamalaikum brother! Thank you so much for this video.. I appreciate your effort. More videos hopefully..
super
Pls make more videos. It's very helpful
Thank you very impormative
Thank you for your video really helped me, please make the same wiring connection of villas..
Can you please make a video about building electrical wiring and electric panel design in AutoCAD Electrical ?
THANK YOU V MUCH
جزاك الله خيرا شرح رائع وجميل ولغه ممتازه
thank you very much. can you make a video about how to design a load schedule
bro we look forward you to upload more practical based videos subject to dewa sewa installation standarda
بارك الله فيك
نتمني فيديوهات مثل هذه عن ستنادرد أبوظبي FEWA
Thanks for well detail explanation, please do video on the DEWA standards for cable sizes and CB sizing
Sure. I am planning to do a complete series on electrical design in general...and as applicable to DEWA standards specifically.
Thank you i love your videos 👍
Thank you.
Please stay tuned for future videos.
100%
thanks eng
How can I get the full course for complete electrical design for building plan
Thanks for a wonderful explanation. But sir how to calculate the size of incoming isolator?
Sir,How much load/ how many circuit connected to a 40A ELCB?
How we calculate voltage drop in load schedule. Like 4% voltage drop calculation?
Nice video 📹 so sir please one video in distribution bord dressing practical hope you can do it
Excellent Explanation. thanks sir Please make a video for Capacitor bank Selection and Voltage drop calculation
Please refer to my latest video for CB selection basics :

Awaiting your new videos brother. I hope you are doing well.
Thanx sir
Why the maximum ampere rating of 13a Single socket outlet is connected only in 200w each onces,and how many 13a sockets can connect.
If the load balancing is more than 20% in any of the phases either R or B, how can we balance the load. (Making spare?)
Sir I have doubt 13a single socket how many watts 1 amps =174watts 174*13=2262 watts right but the drawing there writing 200 w how this pleases tell me
ربنا يكرمك
Hi bro hope u vl b fine and blooming plzzzz upload a video about slap and plzzzz clearly identify the boxs of wifi, emergency light, and fire alarm system
Can u explain a lighting layout and power layout of a building.
Thanks for your elaboration on DEWA Practices. I would like to know, when you have a 32 A TP isolater, and a 40 A ELCB serving the Board, how can the extra 8 Amps be handled safely. Shouldn't they be the same or the ELCB rated less than the isolater?
The 32A rated isolator means that the isolator can handle a maximum of 32A...but it wdoes not have any tripping functionality even if the 32A rating is exceeded.
The upstream breaker in the SMDB should not allow more than 32A to pass tot eh DB so it should be rated at 32A as it will trip if 32A is exceeded.
But for an ELCB...it has 2 rating....Ampere and Milliampere...40A rating means that maximum 40A current can pass through....but you don't use an ELCB as an MCB...you are mainly choosing an ELCB for its mA rating...such as 30mA, 100mA, etc.. which will trip in case of the current leakage exceeding this rating.
@@Electrical_Engineers_Academy , thank you for the clarification. I understand that the ELCB/RCCB device will trip on the rated millamperes. For domestic supply, depending on the Calculated load, commonly 63 Amp /100 Amp Isolators for 3 phase supply is my observation. Most places in Oman, the load schedule is not available next to the DB. Keep up the good work, and I will be looking forward for your new videos. Alf salaam.👍👏🤝
Firstly thanks Engr.Mohammed for the video and appreciate your efforts. I think these neutral links which are sown outside on the right side are located inside Electrical DB itself, Correct me if i am wrong
You're Welcome.
Yes you're right, they are inside the DB itself.
clear explanation, can you pls produce the video for single phase also
Yes, sure. I will be putting a detailed video on how to prepare or extract a DB load schedule from the light/power layouts.
@23:15 u mentioned about radial and ring circuit. Can u explain these wiring techniques in any video?
I will try to give a brief explanation in one of the coming videos.
1 socket we can take 100w in schedule.. Then 3 phase 32A industrial socket how much watts in schedule?
One socket load allocation is 200W as per DEWA.
Industrial socket load allocation is varying, depending on the connected equipment, but typically you can connect up to 5kw.
Any job vacancy for Electrical engineers in uae? I have 2 years experience. Experience not in UAE ..if Any vacancies please inform me
Till how much load can single phase supply take ?
A maximum of 2 AC units (window type) are permitted to be connected on a single phase. If more than that, then 3 phase shall be used.
As a personal standard practice, personally, 8 kW is the maximum that I have connected on a single phase DB.
will you explain why it is 100mA for lighting and why 30mA for power points? also why it is 40A ELCB rating? thanks
Many reasons :
1. To avoid false tripping due to current leakage. Nature of the load dictates this. For example, lights, in their operational mode, usually have high current leakage... There 30mA will cause false tripping. 100mA ensures that it will only trip if there is something wrong in the circuit.
2. For safety and protection of humans. Low level sockets are accessible to humans, therefore you want to provide a small suitable ELCB current rating to ensure that it not permit more than the amount of current that a human can tolerate if anyone get in touch with a live conductor.
@@Electrical_Engineers_Academy Thank you for the detailed explanation...Keep it up
@@Electrical_Engineers_Academy One more thing, how about the lights in the wet areas, such as toilet & bath, why we should use the 30mA and for FCU's should use 100mA.
hi dear can u share me the load schedule link, can i have ur mail id for doubt , as the link attached is not loading
How to Find Diversity factor please make a vedio
The sum of individual max power demand to the ratio of max power demand.
Wer r u man? Why don't u upload videos regularly?
Plz send file...
Sir iwould like to talk to you
