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 ua-cam.com/video/Vfo6oKN2qFo/v-deo.html. 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 UA-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!

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!

So true - the multi-category tags are very convenient! Thanks for the feedback!

Hello there Larry! I very much appreciate your support (and thanks for the shout out on The Revit Kid's podcast - I am honored!). And thanks for this detailed explanation of your process of tracking revisions - yes, color is a valuable tool for this, as well as your extensive tagging - sounds like you are "instance tagging" your walls for individual identification - very clever, and a good example of the "power" of tags! The commercial architects I work with typically tag walls with more of a "type" tag to indicate the wall construction or finish, etc. They do instance-tag doors and windows however, that relate back to an extensive schedule. But to address your point about tracking the "adds" - what immediately pops into my head is the use of Revit's "project phasing" - I've done videos about the built-in "2-phase" approach of Existing and New Construction, but another phase could be added, called something like "Added/Revised" that could be set, like filters, to display in color, to track the changes. This gives me a potential video topic idea! Again, thanks for the support and for following my videos - I'm glad they are useful to you, even as a "non-architect" or "non-engineer" - that is my goal - to help educate as many people as I can. Cheers!

@@ElectricRob I never thought about using that process' Rob. Yes, I do tag a lot by instance It just makes it so much easier in residential. That way I can get right to the point when I'm talking to somebody, or then they text me which a lot of my communication is through with my subcontractors and suppliers, so that everything is documented or emailed. If I have most as an instance you get right to the point of what they're talking about. The only thing that I'm working on now is figuring out how to get the tags to show the same color that I use to show that there has been an upgrade done or an addition to the project. I haven't thought about doing it in phasing. I might have to try that, but if you come up with a video about this man that would be awesome showing the different colors for the electrical fixtures or electrically equipment plus. maybe you'll beat me to the punch on figuring out how to show the upgrades or the changes being made with both the tag and the instance type of family.

You bet - we all started at the beginning, and we all still have things to learn!

Glad it was helpful!

Awesome! I think tags are underrated - especially when first learning Revit, as there are not many creative out-of-the-box tags.

Hey there! So the way Revit works is, as you've noticed, circuits get assigned in order (you can pick that order from a few choices). And then to move circuits, you actually do it within the panel schedule itself. My tutorial episode #05 at timestamp 24:45 shows how to set up the order then move circuits. Good luck!

@@ElectricRob Rob, do you have the option to choose a circuit number or do you have to go with whatever circuit number Revit assigns, then either move or find a device that is on that circuit - like circuit #2, then edit the circuit and add items to the circuit? I did not see any devices when I clicked on the panel schedule, cir #2, but wanted to add a device/light to that #2 circuit, what methods can I use? I watched your video #5 and did not get my question answered. Thank you.

Hey Kameron. Well, like I mentioned in my first response no, you cannot choose a circuit number - when you create a new circuit, Revit assigns the next number based upon the settings. So the video I referenced showed how to move circuits around within the panel, but I see you are asking how to actually add fixtures/receptacles to a circuit. My older video on circuiting receptacles here ua-cam.com/video/n8M5lo-_zMU/v-deo.html at timestamp 24:50 shows how to add receptacles to a circuit that is already assigned - you hover your mouse over the receptacle that is already circuited and hit TAB until the circuit highlights, then select the circuit. Then you can use the buttons on the ribbon to add (or delete) recepts/fixtures to that circuit. Hopefully that demonstrates the procedure. Cheers!

@@ElectricRob Thank you for that. I was able to add the other device to the circuit, based on what you just described for the circuit number that already has devices connected to it. However, this odd one here, has only the panels and I cannot find the other devices anywhere. So to work around that, I created a new device. Then I power it and chose that same panel. I think it automatically assigned the number. Now, I did not make a snapshot of the panel schedule beforehand, so I can't tell me if Revit added that device to an already existing circuit or it places it in an empty one. I expected it to use the very last circuit 20, but it sometimes assigns it to circuit #10, for example. Anyways, so I clicked on the #10 circuit in the panel schedule to see if anything else is selected in the plan view. I think it was only one device (the one I recently assigned), so I moved that circuit in the panel schedule to circuit #2. It changed the #10 to #2, but I think it either overwrites what description was already there in #2, or it added the text in with what was already there (maybe you can confirm). But it did the job. I just hope that I had not moved other circuits that possibly were assigned #10 before I placed the device and added it to the circuit, before moving it to the circuit number that I wanted it to be assigned to. Thank you so much for you response, Rob. I will definitely view all your videos. They're very thorough. I'm pretty savvy with family editing, so I'll check out your videos there as well! 🙏

I'm glad to hear that you were able to add the other device to the existing circuit. And yes, the description of the circuit is part of the circuit itself and moves when you move it within a panel, so yes, it replaces any other description that was in the former area. Also, if you use the "system browser" you can see a list of all devices within your model, and can perhaps help you locate the device you can't find. It shows you what is connected to what circuits, and if you click on it in the system browser, it will highlight within the model as well.

Glad to hear it was helpful! Appreciate your feedback!

You bet - glad you found it helpful!

You're welcome!

Thanks!

Thanks!

Thanks - appreciate the feedback!

Hey John. The only trouble I've had similar to that is when for some reason there is an error in the panel schedule template. In the "panel schedule editor", check the cell that is supposed to contain the sum of the loads for phase B to make sure it is the correct parameter.

Hey there Mark! Appreciate the feedback and support, and thanks for the tip! A very clever way of indicating the existing loads - using the "detail level" to "hide" those connections is a great hack! One drawback I've found to my method is when other trades link my electrical model into theirs, they don't always crop their view the same, such that some of my existing connections actually show up. I'm assuming yours could have the same issue if they don't have the detail level set appropriately, but less likely. And yes, I definitely see the advantages to your method with the simple ability to group and copy them - thanks for sharing! We definitely have to be ingenious sometimes to really make Revit work for us! Cheers

@@ElectricRob It solved a big issue at my firm of placeholders floating around everywhere and trying to "easily" find them later. I also use a similar process for lighting relay/control panels to solve that issue. Stick "relay placeholders" on the face of the relay panel with the needed parameters to fill out the relay panel schedules. Circuit the placeholders with the light fixtures and you end up with a fairly functional relay panel schedule - not perfect but it semi-automates a missing and needed Revit function. Yes, your 100% right about being ingenious to make Revit jump through the hoops we need it too! Keep up the good work!

Thanks for the feedback!
