WOMAN: Creating and Updating Electrical Circuits.

00:04

In this video, we'll investigate existing electrical circuits

00:08

in a project and create new circuits in preparation

00:11

for creating wire diagrams.

00:15

I'm working in the Small Medical Center project in the Ground

00:18

Floor Electrical Plan view.

00:21

This plan view shows lights and power.

00:24

As I zoomed in, you can identify that there are outlets, there

00:28

lights, and there are also tags that

00:31

display the circuit number on the electrical devices

00:34

and light fixtures.

00:37

Plus you can see that there is a filter applied

00:40

that helps you identify elements that have a circuit number.

00:43

Let's take a look at that.

00:45

I'm typing VV and then selecting the Filters

00:49

tab of the Visibility Graphic Overrides dialog box.

00:53

I'm going to take a look at the one called Electrical Check.

00:57

You can see here that it's Electrical Check,

00:59

I've got my filter list set to Electrical.

01:02

I'm going to Hide Unchecked Categories,

01:04

therefore I can see which ones are actually being applied.

01:08

And the rule for this is circuit number contains a hyphen.

01:12

So basically that's just identifying

01:15

that it has a circuit number.

01:17

I'm going to click OK and OK again.

01:22

So everything that's green has actually

01:24

had a circuit applied to it.

01:27

Now in this case, I don't want to see the light.

01:30

So I'm going to duplicate the Ground Floor Electrical Plan

01:34

and I'm going to go Duplicate View.

01:36

Duplicate, this keeps me from having all of the tags on,

01:40

I don't want the tags in this particular view.

01:43

And then I don't need to have my lights either.

01:47

So I'm going to turn those off, I selected one

01:50

and I'm typing VH for View Hide.

01:54

And I'm going to do the same thing for the switches.

01:60

Now I'm ready to check out my outlets that are still not

02:04

connected to a circuit.

02:06

Let's see an existing circuit first.

02:08

I select it and highlight it until I

02:11

see that my electrical circuit and then when I click

02:15

to select it.

02:17

I can see here's my panel and I can edit the circuit.

02:22

So I'm going in to Edit Circuit, add to Circuits

02:25

already applied and I'm going to click on another outlet

02:29

to add it to the circuit.

02:31

I get a warning and this tells me

02:34

that it's exceeding 80% of the defined rating for 20 amps.

02:38

So I'm going to cancel this one, I

02:40

can't add any more to this circuit.

02:42

So instead I need to make a new circuit.

02:45

So I'm going to select one of the outlets that is not yet

02:48

in a circuit and in the Modify Electrical Fixtures tab,

02:53

I'm clicking power.

02:55

Now, the first thing I want to do is select the panel,

02:58

I could actually use select Panel as well

03:00

and go and click on it.

03:02

But this one this is easier in this case and the name

03:05

of the circuit is LP12.

03:08

I'm going to click Edit Circuit and add to circuits available.

03:12

So once again I'm going to work through all

03:15

of these select the various outlets.

03:20

And when I get to a point where, this one is too many,

03:24

I'm going to remove that one from the circuit.

03:29

And then click Finish Editing Circuit.

03:33

I still have a few more outlets, that means

03:35

I need to create another new circuit.

03:37

This time, I'm going to select all the outlets first and then

03:42

create my power system.

03:44

This was a lot quicker.

03:45

It automatically assigned the right panel.

03:48

It selected all of them.

03:49

It assigns the circuit number is LP127, which would

03:55

be the next one in the list.

03:57

So the first step of creating wire diagrams

03:60

is to verify that you have all the circuits connected.

Creating and updating electrical circuits - Exercise

In this practice, you will investigate existing electrical circuits in a project and create new circuits in preparation for creating wire diagrams.

Task 1: Review electrical circuit tags and filters

Open the Small Medical Center-Circuit-2021.rvt project. The Ground Floor Electrical Plan view displays. This plan view shows lights and power.
Zoom in and identify tags that display the circuit number on the electrical devices and light fixtures, as shown below.
A filter is applied to the view that identifies elements that have a circuit number. Type VV to open the Visibility Graphic Overrides dialog box and select the Filters tab. The Filter is called Electrical Check.
Click Edit/New….
In the Filters dialog box, verify that Electrical Check is selected, Set the Filter List to Electrical and check Hide un-checked categories. This filter is applied to Electrical Fixture, Lighting Devices, and Lighting Fixture. The Filter Rule is that there is a Circuit Number and it includes a hyphen in it, as shown below.
Click OK to close the dialog boxes. This filter is helpful when you are building your electrical circuits.

Task 2: Create and update circuits

In the Project Browser in the Electrical>Power>Floor Plans group, right-click on Ground Floor Electrical Plan and select Duplicate View>Duplicate. This duplicates the view but does not include any annotation elements.
Rename the view Ground Floor Electrical Devices Plan.
Select one of the light fixtures and type VH for View Hide. The visibility of the category is turned off in the view.
Repeat the same process with the Switches. The remaining view just displays the outlets, as shown below.
Hover over one of the outlets is connected to a circuit and press <Tab> until you see the circuit and then click to select it. The temporary wiring also displays so you can see which outlets are connected, as shown below.
In the Modify | Electrical Circuits tab > System Tools panel, click Edit Circuit.
In the Edit Circuit tab, the Add to Circuit tool is selected. Click on one the outlets that is not in the circuit.
A warning displays, as shown below. This circuit is already full. Click Cancel Editing Circuit.
Select one of the outlets that is not in a circuit. In the Modify | Electrical Fixtures tab > Create Systems panel, click Power.
In the Modify | Electrical Circuits tab, select the Panel LP1, as shown below.
Click Edit Circuit.
In the Edit Circuit tab, the Add to Circuit tool is selected. Click on other outlets nearby and add them to the circuit. When you get to the warning, as shown below, click Remove from Circuit and remove the extra outlet.
Click Finish Editing Circuit and the new circuit is created. The outlets turn green now because the filter is satisfied.
Use a window selection to select the rest of the outlets that are still uncircuited, as shown below.
In the Modify | Electrical Fixtures tab> Create Systems panel, click Power. This time the LP1 is automatically selected and all the outlets are placed in the circuit.
Save the project.
