I have seen many drawings video from professionals around the world on the Internet, but this instruction set and those related are truly fabulous and best ones I’ve seen. Great job Rob
You are an amazing teacher and that is an understatement. Just watched the whole video for fun. I assume you are based in Oregon. I almost moved to Oregon in 2022 to work for Nortek but it did not work out. God had different plans for me. Found your channel by pure chance and this is a gold mine. I can't believe it only has 3.44k subscribers. People who work for you are truly blessed to have such an amazing mentor. I wanted to ask a few clarifications on this video if you don’t mind: Around 25min mark on the roof power plan, the receptacles near the RTUs are floating. Where are they mounted? Around 42min mark: 43,298A SYMM (PER PGE). Did the utility provide the available fault current on the secondary of the transformer? Or did the utility provide the available fault current on the primary of the transformer as well as the size and impedance of the transformer and you calculated the amount of fault current on the secondary of the transformer (which is 43,298A) using a software (SKM)? Around 47min mark: Is the 3500A MCB on MDP 100% rated (in my opinion it should be)? Demand on MDP is 3179A. Same question on HDP which has 800A MCB. Demand on HDP is 706A. God bless you sir.
Thank you for your kind words! I hope you are enjoying where you are, even if not in beautiful Oregon! And subscribers keep increasing little by little - thank all of you who subscribed! The TH-cam algorithm trickles videos out to people as it sees fit - but Likes, Comments, and Shares definitely help get the word out to folks that can benefit from it so thanks for those as well! As far as your questions - 1. The roof receptacles are shown diagrammatically, which means we left it for the contractor to verify in the field the best place to mount it (happens often in these types of drawings). 2. The available fault current in this case as I recall was provided by the utility at the point of connection between the utility and customer, which is the main switchboard CT terminals - so they accounted for the transformer impedance and even the secondary conductors (service lateral) impedance, which is handy. 3. Because we apply NEC demand factors to each type of load separately (i.e. 125% for continuous loads like lighting, 10KVA + 50% of the rest for receptacles, etc.) then our calculated load already accounts for the non-100% rated gear (since certain loads are already inflated, we don't have to "double-derate" the gear, which for continuous loads would be like a 64% derating). Hope this helps, and thanks for the feedback!
Great...an Easy way to understand the drawings..Thanks for sharing ..One request...Could you please share/send the link to download the drawings you taught us in this video....Thanking in advance
Amazing Stuff for electrical engineers it crazy they dont teach this in college i didnt learn this stuff utill if start working in MEP as a field engineer
Thanks for the feed back! Yes, unless you specifically take classes in something like "building systems" you may not be exposed to this in college. You also might enjoy this video about one-line diagrams th-cam.com/video/Vfo6oKN2qFo/w-d-xo.html. Appreciate the support!
Hey there! I approach bus duct a few different ways, depending upon my needs for the specific project. In this project, I knew the contractor was going to model the bus duct in detail for their installation drawings, so I just showed it in 2D with simple drafting lines - I modelled the connection point with a "switchboard" family, sized down to match the connection point, which let me electrically add my meter centers to it to get my bus duct load summary. On another project where I've wanted to actually 3D model it, I've used mechanical duct, or I've customized individual bus duct pieces and assembled them together. Sounds like a good topic for a video - hope this answers your question!
Thank you so much for great tutorial your channel helped me a lot, if you have projects like this on Autocad could you share it with me I will appreciate that. I am a student and I am taking my first steps to MEP world Thank you again.
Hey there! I'm glad you are finding my channel helpful as you enter this amazing world of MEP! I'm afraid that years ago I moved from Autocad to Revit, so I do not have any CAD videos.
Hey there! You bring up a very good point - coordination between not only the MEP trades but the architecture, structural, fire protection, etc. is a huge issue both during design and construction. In future videos, I will give examples of how this typically works - it definitely varies project to project, especially with the different construction methods such as mass timber buildings!

This is a true master class of reading Electrical plans. Thank you for sharing.
You are very welcome - I really appreciate the feedback!

Sir Great explanation 👍
Glad you enjoyed it!
Great

Thanks for sharing it. Also, a question. What have you used for the bus duct? Revit doesn't have any, as I know.

Kindly explain MEP coordination step by step.which comes first from top to bottom at the corridors
