The 2021 release of rev.
00:06
It saw the introduction of a feature that allows
00:09
the user to choose which phase of a switchboard,
00:12
single phase loads are connected to.
00:14
Prior to this all single phase loads
00:17
connected to a switchboard would automatically be
00:20
connected to phase A with no option for moving them to a different phase.
00:25
In this project, we will review the default panel schedule for a switchboard,
00:30
then look at the options for changing the appearance of the panel schedule.
00:34
By editing the template,
00:36
we will create a heating circuit,
00:38
then use the switch phases feature in rev it to balance the
00:42
loads of multiple single phase circuits across the phases of the switchboard.
00:48
The heaters in this floor plan are
00:50
connected through multiple circuits to switchboard SB one
00:54
as each circuit is created,
00:56
it is automatically assigned a circuit number and phase on the switchboard.
01:02
So let's go ahead and open and review the panel
01:04
schedule for switchboard SB one from the project browser.
01:10
Although it's not clear to see from the panel schedule,
01:13
all the heating circuits in this project are
01:16
connected to phase a of the switchboard.
01:19
The total loads for all the circuits can be seen
01:21
here at the bottom of the only column on display
01:26
to add some clarity to this arrangement.
01:28
It would be necessary to make some simple
01:30
edits to the current panel schedule template.
01:33
Alternatively, a duplicate can be created and edited to suit
01:38
from the manage tab of the ribbon, select the panel schedule templates,
01:43
dropdown menu and choose edit a template,
01:48
change the template type to switchboard,
01:53
then choose the default switchboard and select to open
01:59
select set template options from the ribbon
02:03
and then select circuit table from the list of options on the left,
02:11
change the format for displaying loads to separate phase loads per circuit.
02:18
The preview window now shows all three phases
02:23
choose cancel, then cancel, template from the ribbon.
02:27
Rather than editing the existing template,
02:30
we will change the template for one that has
02:32
already been edited to include the changes we need
02:38
from the ribbon, select change template and select ps switchboard.
02:45
Select a yes at the warning message.
02:50
We can now see that all of the loads connected so far have been to phase a
02:56
change the view to one power,
03:01
then select the four heaters in the room to the top left of the floor plan.
03:07
Create a new circuit that is connected to SB one,
03:14
change the view to the panel schedule for SB one.
03:19
And here we can see the new circuit has also been connected to phase a
03:25
change, the default frame size for the new circuit to 100 amps
03:33
from the panel schedule, select circuit four.
03:37
Then from the ribbon pick the switch phases, command
03:41
and the circuit moves to phase B
03:45
review the total at the bottom as the circuit is moved across,
03:51
repeat the process for circuits five and six
03:56
and again, review the totals at the bottom.
04:02
Go ahead and move circuits 789 and 10 to phase C
04:08
by selecting the switch phases, command twice for each circuit
04:14
once complete review the totals for each column
04:18
where the loads are now more evenly balanced across all three phases.
04:26
When using rev it for electrical design,
04:28
the information in each circuit created and modified automatically updates
04:34
providing invaluable feedback to assist in making design decisions.
04:40
Edit an existing panel schedule template
04:43
or create a modifier duplicate to gain greater
04:46
visibility of phase allocation on a switchboard.
04:50
Then you switch phases to balance the loads on your switchboard and give you
04:55
greater control and a more accurate account
04:58
of the electrical distribution in your project.

Define single phase circuits on a standard switchboard panel schedule.
All circuits are listed under one column with the totals for all circuits at the bottom. There is no reference to the phase the circuits are connected to.
You will change the default template for one that has already been modified with the changes you need.
The switchboard panel schedule now displays phases A, B, and C, and the single phase loads can be seen connected to phase A.
