Circuit Assignment and Panel Management for Level One Power Plans

Streamlining Receptacle Circuiting and Troubleshooting Panel Capacity in Level One

Learn how to assign receptacles to circuits for school building power layouts using Revit. This article provides a comprehensive step-by-step guide, which covers everything from identifying and creating circuits to allocating specific loads and ensuring the layout meets power capacity requirements.

Key Insights

  • Receptacles can be assigned to specific circuits within a power plan by drawing a rectangle around them and filtering out to only the electrical fixtures. Once selected, these receptacles can be plugged into a power system.
  • Revit's intelligent design capabilities allow it to recognize when a circuit exceeds its defined power rating, alerting you to redistribute the load as necessary. This is visible when attempting to add a receptacle to an already filled circuit.
  • When a panel board runs out of slots, its maximum number of single pole breakers can be adjusted in the properties section, which enables you to add more circuits to it. Revit automatically assigns everything accordingly, demonstrating its adeptness in managing power distribution.

Now that we have all of our receptacles placed for our level one power plan, we can assign them to circuits. Feel free to use that PDF handout as a guide for arranging these into circuits. Let's zoom on in here.

If we hover over one of the receptacles in classroom 1510 and hit TAB, we see that first circuit we've already created. We want to continue that pattern. We wanna do it a bit quicker.

We can draw a rectangle around the receptacles for the next two classrooms. It's a quick way to select them all, but I'll need to click on the filter and filter out just to the electrical fixtures and click okay. Now we can plug these into a power system.

And to keep it simple, we're just going to place all of these onto panel board three here for level one. And we're gonna start to fill up that panel board. So in a little bit, we'll see what happens when it gets full and how we can remedy that.

But we can give this a name and we've already used a load name before for our classroom receptacle. So it will now be in this dropdown list and we can select it, receptacles classroom. It's best to select it so we don't get any misspellings as we work along.

So let's move along. We will do right here, the next two classrooms. I'm noticing that I skipped a receptacle in the nurse's office.

And that's okay. If you miss one like I did, we will do create similar and just add another receptacle back in. And now we can select the two classrooms and that nurse's office.

Filter out to only the electrical fixtures. Click okay and click the power button. Panel board three and our load name is receptacles classroom.

Pretty straightforward, right? Oh, but I messed up. It looks like I didn't get the GFCI outlets. Not a problem.

I can click the edit circuit button and simply click and add those two to the circuit. Now I'm getting a total connected apparent power for circuit A is exceeding 80% of the defined rating for 20 amps. So it's 20 amp circuit.

Adding that nurse's office was too much. So Revit is pretty smart in how it does this. So let's go ahead and hit finish.

And I might want to go ahead and alter the circuit here. We're gonna break a little bit from that PDF handout. That's okay because we're learning and we're gonna add these to their own circuit.

So let's go ahead and grab the two electrical room receptacles. We'll power those up. We will say panel board three.

And let's see, we've got load name. It can be receptacle and that's fine. This is no longer a classroom.

So load name, just receptacle. And we can edit that circuit. And I want to remove the receptacle from the nurse's office from that other circuit that was overloaded.

It's pretty easy to just add it to our electrical room circuit. So let's go ahead and add the circuit, click on that receptacle. It will give us a warning and say, hey, you're pulling from another circuit, but that's okay.

That's what we want. Now if we hover over this and hit TAB, we've got that circuit for nurse's office and electrical room. And if we tab over here, we have the two classrooms and they're okay now because we've removed that nurse's office.

All right, so we'll repeat that process. I'm going to go ahead and pick the next two classrooms here. And I'm going to filter those out and I'm going to grab the electrical fixtures, power them up, panel board three, and the load name here, receptacles classroom.

And I messed up again. I missed one right here. Not a problem, edit circuit, add it.

And there we go. If I hover over one of these and hit TAB, I can visually see that circuit. It looks good now.

Now let's go ahead and do the next two classrooms here. Right there, filter out, check none, electrical fixtures, powered up, panel board three, and our loads, we'll give it a name, receptacles classroom. And the last two are a classroom and the break room all together.

So I'll grab all these. I'm going to hold shift on my keyboard. I grabbed one accidentally.

Now I can filter out electrical fixtures and power them up, panel board three, load name, receptacles classroom. Good to go there. Okay, let's zoom into the lower area and I'll repeat that process.

I'll try to go quickly here, two classrooms at a time, grab everything, filter, electrical fixtures, power them up with panel board three. And here we go. You can't connect to panel board three because there aren't enough slots.

And the feed through lugs is unchecked. We don't want feed through lugs. We want these to be on circuit breakers.

We don't want to enable feed through lugs. We're going to hit cancel. What is our problem here? The problem is we don't have enough slots in panel board three.

So panel board three, we did them right to left looking at this wall. That's PB1, you can kind of hover over and get the little readout on what they are. So PB1, PB2, PB3 right here.

And we'll notice if we scroll down in its properties here under electrical circuiting, max number of single pole breakers is set to 12, which is kind of small for a 200 amp breaker. It might be more like 42 typically. We'll say apply.

And we've got now 42 slots. So let's try that again and see if we can add it to that board. If I hover over one and hit TAB, it did create the circuit.

Revit will create the circuit. It just puts it on panel none. We want to assign it to panel board three.

And that time it did no problem because now we have the slots. So Revit is pretty smart in how it's assigning everything. Let's just go back to the properties, make sure we give this a name and it is receptacles classroom.

There we go. We've made some good progress. Let's go ahead and check out the systems browser and see what's going on there.

If I go to view tab and then user interface and turn on my system browser, there it is. I can see that under electrical power, main distribution board three, panel board three, I now am creating these circuits. If I open these up and go, I've got the lighting as the upper circuits.

Let's go to the bottom one, 13. Now I can see I've got these receptacles. And so it's all working out.

Revit's all connected. You can see it's super smart. It knows how many slots we have on each of these panel boards.

Pretty cool, right? So let's keep going. I'm gonna add in these classrooms right here, two classrooms at a time. Filter our results, our selection to electrical fixtures, powered up, panel board three, load name, receptacles classroom.

Now we've got a workroom and a classroom here that belong together. We'll grab those receptacles here, filter them out to electrical fixtures. And we didn't get the power button.

Why is that? Probably because this receptacle is already on a circuit. So what we need to do instead is click this guy and click on its circuits. Let's see.

If I click tab and click, you can see it's a tiny circuit. Nothing else is associated with it. So let's first give it a panel board, panel board three.

You can see that rectangle expands to show it connects now to panel board three. And I need to edit the circuit and add to the circuit. Now we'll add all of the receptacles from classroom 2001.

And I want to now give it a load name, receptacles classroom. And I'm good. When I hit finish, it's gonna jump from unnamed or should over to, yep, there we go.

It's now number 15. So it's pretty cool. We're starting to assign some of the unassigned items that were up there.

All right, so let's go now to our left bottom left corner. I'm gonna grab two classrooms at a time, grab all these, filter it out, electrical fixtures, power it up. And we know the drill pretty well by now.

We're gonna repeat this process down the line, receptacles classroom. And we're almost done with these classrooms. I'll select the next group of two, filter these out, check none.

And I wanna power them up. And I will set the load name to receptacles classroom. And we're good to go.

Panel board three. Now the next and last final two classrooms. There we go.

Select, filter, check none, electrical, okay. Power them up. Panel board three, load name classroom, receptacles.

Phew, we got them all done. Nice work. Now we'll notice a couple of other receptacles like here.

If I hover over this and hit TAB, it's already set as a circuit. And it's in unnamed. All I have to do is give it a panel board.

So PB3, you'll see it jumps down. It's number 19 there now. And the load name, we can call this receptacles corridor or just a receptacle load.

We'll just call it receptacle and keep it simple. Kind of differentiate between classroom receptacles and everything else. Pretty quick way to go.

All right, so that looks good. We can do this other corridor here. Hit TAB, there it is.

And we can set that to PB3. And we want to give it a name that this is receptacle. Okay, let's come over into our cafeteria.

Let's hover over, hit TAB. Looks like we don't have circuits here. We need to assign these to a circuit and hit control.

Grab these floor boxes. There we go. Floor boxes and a couple of receptacles on the wall.

Oh, and one of these unnamed lit up. Now it won't connect. I have to remove it.

So that one, that one, and that one. Just the floor boxes for now. We'll click on power and we'll set PB3.

We'll change the name here to receptacle. And we need to add in those other two, three wall outlets. We'll click edit circuit and we'll select these.

It will give us a warning. We're pulling them out of that unnamed circuit, which is what we want to do. And click finish editing.

So there's one less unnamed circuit that pops down there. Okay, let's hover over the kitchen. There we go.

Hover, hit TAB. It's all an unnamed circuit. I'm going to add that to panel board three.

It's going to think about it for a moment and we'll give this a name, receptacle. Awesome, that looks really good. Now we added these receptacles in the gym, so it's on us to power them up.

We're going to grab kind of the top and left receptacles all into one circuit. So the three across the top, three across the left, that will make a circuit here. And let's go ahead and add this outlet as well.

So kind of wrapping that left side, power them up. There we go, PB3. We'll give this a name.

And receptacle. Now we'll do the right side of the gym. So I'll grab this receptacle and these three.

And I think that's it for that one. We'll hit power, power it up. PB3 and load name receptacle.

Rev, it's on to us now. It already populated receptacle. We're good to go.

Now it can come down to our library. And what we want to do is first power these wall outlets into one circuit in the main library area. And we'll hit that power button.

PB3 receptacle, we're good to go. Then we'll add in these floor boxes as their own circuit, just three floor boxes, power them up. PB3 and our load name, we'll call these receptacle.

Over in the vestibule, if we hover over that and click one time, we can see it's already assigned to the corridor. Let's try this corridor, hover over, hit TAB. That one's not assigned.

So these ones need to be selected. We start in the vestibule. We've got two receptacles there, kind of zigzag across the hallway, grabbing all those.

Now this circuit continues on up this hallway. If I hold control, that power button went away. So I'll have to unselect that, power this up.

PB3, load name, receptacle. All I have to do is click edit circuit and I want to add the remaining hallway receptacle. So there's one, it's going to warn us I'm moving it.

One of those unnamed circuits will disappear once we get them all. Here we go. And last one, I think that's it.

We've got all of those selected and we'll do finish editing. If we hit TAB over that, we'll see that they're all selected and that is looking pretty good there. Okay, let's keep going.

We've got these restrooms and we created these receptacles. We can also create this circuit here. We'll grab all these guys and we will power them up into a circuit for our restroom and janitor area.

So again, power button, PB3, receptacle, and we're good to go. Hit modify. Okay, that should be about it.

What we want to do now is go ahead and follow that guide, go to your level two power plan and repeat the same process. Add in the missing receptacles and assign all of those receptacles to a circuit.
