Work with phase selectable switchboard circuits
Define single phase circuits on a standard switchboard panel schedule.
Step-by-step guide
Define single phase circuits on a standard switchboard panel schedule.
- Open the project E02_03.rvt. Ensure the current view is Power > Floor Plans > 1 – Power.
- Note the heater positions in the rooms of this floor plan. All the single phase circuits here are connected to the switchboard SB1.
- From the Project Browser, open the view for the switchboard panel schedule SB1.
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.
- In the Manage tab, Panel Schedule Templates drop-down, choose Edit a Template.
- In the Edit a Template dialog box, change the Template Type to Switchboard.
- Select the template Switchboard (Default).
- Click Open.
- From the ribbon, click Set Template Options.
- In the Set Template Options dialog box, click Circuit Table.
- To display all three phases of the switchboard in the panel schedule, the option Separate Phase Loads per Circuit must be selected. Do not make the change, and click Cancel to close the window.
- Click Cancel Template from the ribbon.
You will change the default template for one that has already been modified with the changes you need.
- From the ribbon, click Change Template.
- Choose PS Switchboard.
- Click OK.
- Click Yes to close the warning message.
The switchboard panel schedule now displays phases A, B, and C, and the single phase loads can be seen connected to phase A.
- Switch the view to 1 – Power, and then select the four heaters in the room in the top left corner.
- Create a circuit and connect to switchboard SB1.
- Return to the panel schedule for SB1, and note the new circuit has been assigned to phase A with its values totaled in the same column.
- Change the frame size for the new circuit to 100A.
- From the panel schedule, select circuit number 4.
- From the ribbon, click Switch Phases to move the circuit across to phase B.
- Note the new position of circuit number 4 and the totals at the bottom of the column.
- Repeat steps 20 and 21 to switch circuits 5 and 6 to phase B. Note the updated totals.
- Repeat steps 20 and 21 and switch phases for circuits 7, 8, 9, and 10. For each circuit, click the Switch Phases command twice to move it to phase C. Note the updated totals.
- Save the project.
