DEWA Electrical DB load schedule EXPLAINED - A detailed explanation

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.

Nice video 📹 so sir please one video in distribution bord dressing practical hope you can do it

[@boroboro8278]

Thank you i love your videos 👍

[@Electrical_Engineers_Academy]

Thank you. Please stay tuned for future videos.

[@ghousequadri9756]

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

[@Electrical_Engineers_Academy]

You're Welcome. Yes you're right, they are inside the DB itself.

[@mohamedfazil5240]

clear explanation, can you pls produce the video for single phase also

[@Electrical_Engineers_Academy]

Yes, sure. I will be putting a detailed video on how to prepare or extract a DB load schedule from the light/power layouts.

[@juliuscastillo2241]

Thanks for a wonderful explanation. But sir how to calculate the size of incoming isolator?

[@MrCuteGamingofficial]

THANK YOU V MUCH

[@rajanvarghese2352]

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?

[@Electrical_Engineers_Academy]

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.

[@rajanvarghese2352]

@@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.👍👏🤝

[@thahakayaralam8598]

Can u explain a lighting layout and power layout of a building.

[@iqrascookingandislamtv2481]

Thanx sir

[@shahkam3994]

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

[@ahmedelsharkawy3760]

[@mustafaghori3575]

How we calculate voltage drop in load schedule. Like 4% voltage drop calculation?

[@user-bv7eh5js6e]

100% thanks eng

[@abz831]

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?)

[@zairwani]

@23:15 u mentioned about radial and ring circuit. Can u explain these wiring techniques in any video?

[@Electrical_Engineers_Academy]

I will try to give a brief explanation in one of the coming videos.

[@sujeethms5212]

Sir,How much load/ how many circuit connected to a 40A ELCB?

[@FrankElimihele-ot7db]

How can I get the full course for complete electrical design for building plan

[@xavierthankaraj1381]

How to Find Diversity factor please make a vedio

[@abdulraheemmohammedarif4198]

The sum of individual max power demand to the ratio of max power demand.

[@lenyr7905]

will you explain why it is 100mA for lighting and why 30mA for power points? also why it is 40A ELCB rating? thanks

[@Electrical_Engineers_Academy]

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.

[@lenyr7905]

@@Electrical_Engineers_Academy Thank you for the detailed explanation...Keep it up

[@lenyr7905]

@@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.

[@teja7733]

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

[@nallavar1]

1 socket we can take 100w in schedule.. Then 3 phase 32A industrial socket how much watts in schedule?

[@Electrical_Engineers_Academy]

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.

[@Vivekvvooz]

Till how much load can single phase supply take ?

[@Electrical_Engineers_Academy]

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.
