Create and edit circuits

00:01

In this lesson we will cover creating and editing circuits and adjusting circuit properties.

00:10

In this model, lighting fixtures have been placed along with some of the electrical devices.

00:18

At this point you can begin creating circuits.

00:22

You can create circuits for power systems along with some low voltage systems such as data, telephone and fire alarm.

00:33

In this lesson, we'll look specifically at power systems.

00:37

And the important thing to keep in mind is that only compatible devices can be connected,

00:43

and that means that they have the same distribution system which is made up of the voltage definition and the number of poles.

00:52

We could take a quick look at that.

00:53

If we switch to the systems ribbon and in the electrical panel will click the dialog box launcher,

01:00

and then we'll look at the distribution systems settings

01:05

and you can see that it's made up of the phase configuration, a number of wires and L. L. Voltage and an L. G. Voltage

01:13

and those voltage come from the voltage definitions here and so there is a minimum and maximum voltage.

01:21

So there's a range here to make up these voltages and then once again they can be selected here to make up the distribution system.

01:31

Now when we take a look at the components that can be added to a circuit,

01:38

the important thing to keep in mind is that they must have an electrical connector.

01:43

So I'm going to select this receptacle and click Edit Family.

01:48

And when I look at the family I can see the electrical connector here,

01:53

and when I select it you can see that there is a system type parameter and so this one is set to power unbalanced.

02:01

But as I described earlier you can create circuits for several other types of systems such as data, telephone security, so on,

02:10

and once again power, power is the main one we're focusing on.

02:15

And the important thing to keep in mind with power circuits is the voltage.

02:20

And so here's a voltage.

02:22

All of the electrical connectors will have a voltage parameter,

02:27

and this one in particular is associated to a family parameter which is the switch voltage.

02:33

And so that's where the voltage of this receptacle can be controlled.

02:39

Okay, So once again to be added to a circuit, it must have an electrical connector,

02:46

and you need to pay attention to the voltage and the number of poles and the system type for each connector.

02:55

Okay. We'll close that family and go back to the model and let's create a circuit for these receptacles.

03:03

So if I select a receptacle, you can see that in the contextual ribbon.

03:08

There's a create systems panel and power is available and that is due to the electrical connector that we just looked at.

03:18

When I click power, a circuit is created and right now that only that single receptacle is added to the circuit.

03:27

But at this point we can click edit circuit and go into edit circuit mode,

03:32

and then there are a couple options here add to circuit and remove from circuit.

03:38

So with add to circuit selected, I can begin selecting other receptacles,

03:44

or even other once again other compatible devices that could be on the circuit.

03:49

So in this case I could add lighting fixtures that are 120 volt.

03:54

I'm simply going to continue selecting receptacles.

04:02

And in a minute I'm going to get a warning and there it is.

04:04

So it's now it's telling me that the total connected load for the circuit is exceeding 80 of the defined rating.

04:11

And so right now the rating for the circuit is set to 20 amps and I'm exceeding 80 of that capacity.

04:19

And so Revit is going to warn me of that.

04:23

So I can select remove from circuit and I'll remove a few of these devices,

04:30

and so you'll notice that as I'm adding components as I'm adding these receptacles to the circuit they are becoming bold,

04:38

and the ones that are removed they are now dimmed and so that will tell me which components have been added to the circuit.

04:47

Once I have the all of the fixtures that I want on this circuit I can select the panel.

04:55

There is a drop down and I can expand that drop down and I can select the panel,

04:60

or if I wanted to if it was visible in the view which in this case it is I want to I want to assign it to L. P. one.

05:09

I can click Select Panel and then select the panel in the drawing area.

05:15

Once again I can I can select it from the drop down or click select panel and then select it,

05:22

and then once I have that finished I'll click Finish Editing Circuit and all of my receptacles that I selected are now added to the circuit.

05:32

And when I select them you can see the electrical circuits contextual ribbon and the ones that I removed those are obviously no longer on the circuit.

05:42

Another way to create a circuit is to select those components beforehand.

05:48

So I'll select a handful of lighting fixtures,

05:51

and when I do once again power is available and the contextual ribbon and I'll click Power and only the selected devices are added to the circuit.

06:04

I can select one of the fixtures in the circuit and switch to the electrical circuits contextual ribbon,

06:11

and I can click Edit Circuit and add additional fixtures if I wanted to

06:16

and also be aware that those were added to panel L. P. One and that's because panel L. P. One was the last panel that I used for a circuit.

06:25

And so Revit will remember that and continue to add circuits to that panel.

06:32

And so if you wanted to change that panel you could do so by expanding that drop down and selecting another panel,

06:40

and then Revit would use that for the next one.

06:45

All right. So we have two circuits created.

06:48

We added the electrical fixtures and the lighting fixtures to a circuit.

06:54

Now let's take a look at.

06:55

We could we could obviously continue doing that throughout the building.

06:58

A couple more things I want to cover is we can circuit panels to other panels.

07:03

So in this case we have panel L. p. one and when I select it, the power button appears in the contextual ribbon,

07:11

and I can create a circuit for that and we can connect it to the transformer,

07:17

so I can expand the panel drop down in the contextual ribbon and select the transformer.

07:23

And then we can do the same thing, create a circuit for transformer and connected to panel M. D. P. one.

07:33

All right.

07:34

Last note I'll make about circuits is when you're connecting them two panels and specifically panels to other panels,

07:45

there's the option to control the connection type and it can either be through a breaker or feed-through lugs.

07:53

And if you want to use feed-through lugs the that option must be enabled.

07:59

And so just for example, I will copy this panel and when I selected I'll click Power and it's set to M. M. D. P one.

08:11

And since the connection, the feed through types, sorry, feed-through lugs option was enabled, I can select that for the connection type.

08:22

So pay attention to that.

08:26

So just to summarize, the components must be of the same distribution system,

08:32

and we did not cover panels that they do have a distribution system parameter so you can control that,

08:40

and then transformers, they actually have a secondary distribution parameter and you can control that as well.

08:49

And so pay attention to the voltage number of poles, which make up the distribution system so that you can create circuits.

Now when we take a look at the components that can be added to a circuit,

01:38

the important thing to keep in mind is that they must have an electrical connector.

01:43

So I'm going to select this receptacle and click Edit Family.

01:48

And when I look at the family I can see the electrical connector here,

01:53

and when I select it you can see that there is a system type parameter and so this one is set to power unbalanced.

All of the electrical connectors will have a voltage parameter,

06:58

A couple more things I want to cover is we can circuit panels to other panels.

08:49

And so pay attention to the voltage number of poles, which make up the distribution system so that you can create circuits.
