To create a panel, go to
DM Electrical
One Line DevicesPanels
A Panel dialog box will appear. To actually create a new panel, press the New button at the bottom of the dialog box. Another Panel dialog box will appear after Design Master asks you to enter the callout for the new panel you are creating.
Listed below are all the different fields and inputs found in the dialog box above. These fields all help to define the panel in some way and are divided into three main categories. The first portion focuses on the definition of the panel itself, followed by the fault analysis information, and then the specifications of the panel feeder wires.
General Panel Definition
Field |
Sets |
Volts |
The voltage and number of poles for the panel |
Bus Amps |
The amp rating for the panel |
Main Disconnect Type |
Indicates the type of disconnect the panel uses. |
Main Disconnect Amps |
The ampere rating for the main breaker or fuse, if the panel has one |
Mounting |
Mounting type for the panel |
Panel Neutral |
Size of the neutral bus (which should not be confused with the feeder neutral conductor) |
Number of Poles |
Number of poles in the panel |
Circuit Offset |
Allows you to create a multi-section panel. Sets the number of poles that the panel is offset. If you set it to 42, then the panel will begin on circuit 43 and go to 84. |
Lugs |
Lug style, either Standard, Feedthru, or Double |
Panel IG Bus |
Indicates whether or not the panel contains an Isolated Ground Bus. |
Plan View Block |
Indicates the size of the panel graphic that appears on the drawing. Custom Rectangle draws only a rectangle, while Custom Panel draws the panel and the clearance area as well. |
Custom Dimension |
Input for defining customized panel block sizes. |
Layer System |
Indicates what layering system the panel block will be drawn on. |
Schedule Block |
Allows you to select the panel schedule graphic to associate with the panel. |
Location |
|
Note 1 |
Creates a note in the upper left hand corner of the panel schedule. The note may also be inserted with the panel on the one line diagram. |
Note 2 |
Creates a note immediately below the panel schedule. The note may also be inserted with the panel on the one line diagram. |
Fault Analysis
Field |
Sets |
Feeder Length (ft) |
Length of the conductor from the device feeding the panel. Can be automatically calculated by Design Master, or input manually. |
Fault @ Panel (amps) |
The fault current at the panel primary. Can be automatically calculated by Design Master, or input manually. |
Panel AIC Rating |
The AIC Rating for the panel is set manually here. There is also a field to enter a custom AIC Rating below this one. |
Feeder Specification
Field |
Sets |
Fed From |
Displays where the panel is fed from. See the section on One Line Device Connections for more information. |
Description in Upstream Device |
How this panel appears in the schedule of the device feeding it. Defaults to Panel Callout, but may be customized |
Upstream OCP |
Size of upstream breaker or fuse in the device feeding the panel. |
Conductor Amps |
|
Neutral |
Choose to size the neutral wire at 100% or 200% of the phase conductors, select a specific conductor, or have no neutral at all. |
Ground |
Choose to automatically size the ground per the NEC as a service or equipment ground, or select a specific size. |
IG Conductor |
Allows you to toggle on or off an Isolated Ground conductor. |
Conduit Size |
Choose to size the conduit automatically, or select a specific conduit size. |
Size |
This field displays the conduit and feeder sizes for the panel, based on the settings above. |
New
To create a new one line panel, from the Panel dialog box described above press New. The New dialog box will appear.
Enter the name of the new device, and then press OK. The device is now created and ready to be defined as is evidenced by the appearance of the newly created panel callout in the Panel dialog box described above.
Copy
To copy a one line panel, from the Panel dialog box described above press Copy. The Copy dialog box will appear displaying the name of the old device.
Enter the name of the new device, and then press OK. The device is now copied.
Save
If you attempt to exit or move to a different device after editing, Design Master will ask you if you want to save any changes you have made. To save a one line device after editing it, press Save. No dialog box will appear, but the device has been saved.
Delete
To delete a one line device from the database, press the Delete button. Design Master will ask you if you are sure you want to delete the device, to prevent accidental loss of information.
It is also necessary to remove any connections to the device you want to delete. For example: a panel may not be deleted if there are still light fixtures circuited to it. The Delete button will be grayed out and unavailable until all connections have been removed.
Rename
To rename a one line device, press the Rename button. The Rename dialog box will appear and ask you to enter the new name for the device.
Design Master will also display a reminder that you need to run the Update Circuit Labels on Drawing command to make sure that any circuits and homeruns are updated to match the new panel name. The program will display this alert regardless of whether or not there is anything circuited to the one line device or not.
Find
To select a specific one line device to work with, use either the Find, Next, or Previous buttons. Next and Previous will move you to the one line device before or after the current device, and the Find button will allow you to search a list of every device and select the appropriate one via the Select One Line Device dialog, as seen below.
