Hah! Yes, you are correct. I have the symbol backwards! Shows how often I actually deal with DC, which actually wasn't my main point of this video, but good catch!

Wow nice! It's alot of work to do complete - congratulations!

@@ElectricRob you are right. I spent lots of time watching and practicing. Just a quick question: as I'm practicing both Revit and CAD, do you have any referral videos for CAD course specifically in electrical design? Really appreciate your help

Thanks! Glad you liked it!

Glad it was helpful!

Yes, most definitely. You can get as detailed and complicated as you like. You can tell that my family modeling is not super detailed, since my electrical models typically need connections and loads, etc. But if you are looking for a more detailed accurate 3D representation of certain items, you can get very fancy. Does give me an idea for a future video though! Thanks for your feedback!

I wish I had a more positive answer for you, but Revit's voltage drop calcs are VERY limited - in short, it takes all of the load of the circuit and puts it at the farthest load point to calculate the drop, then automatically upsizes wire per the percentage thresholds that you can control. So it does not do section-by-section type voltage drop calcs between site lighting poles that we need. Now you can create your own schedule that your have done calcs separately from Revit, and have tags on your wiring tied to it if you like. There are ways to add wire sizing "text" fields to the wires, etc. I did a video recently about Revits voltage drop and wire sizing limitations if you haven't seen that one yet here kzbin.info/www/bejne/iJKumKqkmtyHeqs. Thanks for the feedback!

Hey there! That is a nice visual setup - I've done things similar, and have seen many different systems, some using text in the linetypes or next to the devices, etc. - nice that yours works in black & white or even in color. And yes, having a family type for each of the different visual styles is a great way to do it as well. Luckily Revit does have quite a bit of flexibility in the family editing. Thanks for the feedback!

Glad you found it helpful! It's an old video, but still relevant. If you want more current info, might want to check out something like my full project video here kzbin.info/www/bejne/noerY4aljtqrj5Y - Cheers!

Hey there! Thanks for the feedback! Receptacles typically only have one circuit (the family only has a single electrical connector), so I'm not sure where you are seeing two circuits? A special family could be created that has two connectors for two circuits if needed (like I show in my 2-circuit EV charging point video, or in my 2-source transfer switch video).

@@ElectricRob This one is a special receptacle. It's not a duplex type. It is a 2-pole, so it can only take 2 circuits. I had to change out the family type in order to assign it a single circuit. Can a w-pole device have a single 240 v circuit?

@@KameronManyrath Ahh gotcha! I was thinking 2 separate circuits, but you are referring to a 2-pole, so technically a single 2-pole circuit, but yes, takes up 2 "circuits" in a panel. But to answer your question, if the # of poles is an instance or type parameter, then yes, you can change it to 120V and 1-pole. If not, then a different receptacle is needed.

Hey there! Great question - Yes, in short, the "load" , in this case your receptacle(s), must be compatible with your "source", in this case a panelboard. And to be "compatible", your load must fall within the range of voltages and poles that your panelboard is set for. For example, a 120V (single-pole, of course) receptacle can be connected to a panel that has 120V in its "distribution system" instance parameter - so the panel must be a 120-240V 2-pole or 3-pole distribution system, or a 120/208V 2-pole or 3-pole distribution system, for example. Said another way, a 120/208V 3-pole panel can accept a 120V-1p load, a 208V-2p load, or a 208V-3p load. I have videos on my channel that go over this type of stuff in detail - for example in my "residential project" series, specifically this video kzbin.info/www/bejne/fH-9dXSHeNqmocU

​@@ElectricRob perfect thankyou so much. Additional question to this: We connect the receptacles to the panelboard. And then the panelboard gets connected to the main board and eventually city circuit outside? How do we show this in Revit? Like how do I resolve the warning that Revit shows when a panelboard is not connected to another main board? .. Do you generally show the entire hierarchy of connections in a project or is it just Receptacles to Panelboard? Thanks again..

Hey there! I show the connections that I need for showing the load on panels, other equipment, that I want a load summary for sizing, or proving the existing sizing. So most typically, I connect everything downstream from my main distribution board in my building, which I need to size that board. I don't have to size the utility transformer outside, so I don't connect my board to that (which would just be the same load as my single main board anyway, so would be redundant). Hope that answers your question!

Hah! My personal tagline creator!

Also how did you create the existing parameter to change to that line type

Hey there - thanks for the support! So I think you are looking for a panelboard type one-line symbol that is not just a fixed size, but that can be adjusted to a larger rectangle, for example? I could show how to make such a family, plus would be happy to send it to you. One version could be with "type parameters" and another could be "instance parameters" for maximum flexibility.

Good question - I created the dashed linetype first, then pretty much drew two versions of the symbol - one with solid lines and one with the dashed lines. Then I controlled the "visibility" of each of those versions with the "Existing" parameter, which is a Yes/No type of parameter, that toggles back and forth between the two versions. I can also do a video on this process if interested. Cheers!

@@ElectricRob Yes that is what I am looking for! Thanks Rob :)

@@ElectricRob I am interested. :)

Appreciate the support!

Hey there - too kind of you - thank you for the support! So you are looking to model 3D conduits for receptacles - like a surface-mount situation?

Actually, re-reading your comment, I think you are looking to add within the receptacle family conduit connectors - yes I can do a video for that!

@ElectricRob Yes sir! Actually I did found some resources about how to create a receptacle step by step with the possibility of adding a conduit connector. It's a very interesting process to create a new element:-) ! Would be even more work efficient if there is the possibility to do it on an existing element, to save some time though..

It definitely takes some getting use to! What are your main objections?

@ it looks like quite a lot of work is needed just to create a floor plan for other trades to use.

Hah! Love it!

Appreciate your feedback, and so glad you found it helpful! Feel free to share it with others (thanks!) to help them find it faster!

Appreciate your feedback - tried to be as thorough as I could!

Thanks for your support!

Hey there Bryant! Appreciate your feedback. Interesting topic you bring up - wire size in Revit. I plan to do a full video about how Revit handles wire sizing (spoiler - it's not quite perfect!). But basically, wire size is first selected by the size of breaker you select, and then it gets adjusted by the voltage drop in relation to the "maximum voltage drop" thresholds that can be tweaked in the electrical options. So TLDR (short answer) - YOU cannot directly select the wire sizes! If you want larger wire, you must use a larger breaker (or fake it by making the length longer, load higher, or even voltage drop threshold lower). So as you can see, not really per industry practice. Hope this helps!

@ thanks for the feedback. I will definitely look for that video when you post it. I really tried to find a way to get it to work but haven’t been successful yet, so I’m using our excel schedule for now. Your video on panel schedules helped me create a good template I’m hoping to use in later projects, but only when I’m able to fix the wire size problem. Thanks again.

So it sounds like you would like to indicate wire size within your panel schedule. You can add a column to your panel for Wire Size, and then just manually enter a Text for the size (i.e. #12), and thus not rely on Revit's wire sizing system. Would eliminate the need for those Excel schedules!

@@ElectricRob Yes. We usually show the # of wires, wire size and conduit size. I did try the text as you suggest. However something I just remembered now as you mentioned this. The bottom of the schedule that shows the total connected loads. Unfortunately, our mechanical engineers are only using CAD, so I can’t connect any of their loads to the schedule which means those loads won’t be accurate. I tried to put text in there but there was no option for text. That’s probably a whole other problem.

Ahh I see! So it sounds like you model and connect things like receptacles, lighting, etc. that you actually design, but not the mechanical equipment. You can easily (and this is how we do it) put a mechanical equipment connection into your model that contains all of the electrical information (that you get from their CAD plans, schedules, and even cut sheets) so that you can circuit those to your panel as well, and all of your loads will end up on the schedule, and classified by load (and associated demand factor). Even when we have a linked-in mechanical model, we add our own "connection" with the data that we control, for circuiting to our system. Hope this helps!

Thanks for the feedback!

Hey there Rachel! I'm so glad it was helpful for you - it's actually a bit advanced (with the tapered pole and nested families) so I'm impressed you were able to follow along! Appreciate you watching and your feedback!

Thanks for the kind words, and I appreciate the recommendation!

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 kzbin.info/www/bejne/jJfSZ6KBg5ekfNE. Appreciate the support!

Appreciate the support, and you're welcome!

Hah! That is exactly why I teach about this issue! I suffered many hours of frustration and anger because of this! And I'm glad you are enjoying the videos Larry - thanks for all the great feedback!

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 KZbin 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!

Hey there! The accelerating current is the increased current that the motor draws when it is accelerating from rest to its normal cruising speed. It lasts longer than the "starting current" but is considerably less (starting, or locked rotor as you note, if not on a soft-start or VFD starter, could be up around 6 times the normal running current). So we use this value as the load in our panel, however the elevator manufacturer typically recommends what overcurrent protection size to use.

Appreciate the feedback! Yes, always something to learn, even after doing it for years! I'm glad you are finding some helpful info here. Cheers!
