Details Tab (Loads Assigned Tab - MCCs and Switchboards)

Different versions of this tab are available for horizontal and for vertical busbars. The image below displays an example of the tab displaying details of a horizontal busbar (see later in this topic for an example of the tab displaying Vertical busbar data). The General section of the tab is common to both versions.

The General section is used to view and edit additional details of a busbar, specifically its name, description, Rated Voltage (cannot be edited), Rated Load, Rated Current, Fault Current and Supply Class (which may be distinct from that of the MCC or Switchboard).

Details Tab for Horizontal Busbars - Incomers Section

For Horizontal busbars, busbar incomer protection devices may be viewed, added and edited to using the Incomers section of the tab.

This section also includes facilities to create wiring for incomers by applying wiring rules. Refer to Create Wiring for Supplies for further information.

Incomer protection devices are added by assigning a supply to the busbar. As part of this procedure a compartment and a protection device within that compartment are selected. If no unused compartments or elements are available, they will be automatically generated.

To assign a supply:

1. Click the Assign button. The Assign Supply window is then displayed:

   

   All available supplies are listed. If a transformer has more than one winding defined, each will be listed.

   Depending on the supply type, the Circuit column will display the default circuit (for distribution boards) or spare (for MCCs and switchboards) for each supply (if they have been defined).

   If required, a different circuit/spare may be selected from a list of values in this field, if more than one has been defined.

2. To select a supply, double-click on it, or click on it and click Select. If required, multiple supplies may be selected from the list.

   If the selected supply is a distribution board without any circuits defined for it, the following message will be displayed.

   

   A circuit must be defined for the distribution board before it can be selected (see Supply Details - Loads Assigned Tab - Distribution Boards).

3. If more than one unused compartment is available, select it from the Compartment list. If there is only one compartment available, this will be the only one listed.

4. If the selected compartment has more than one element available, select it from the To Element list. If the compartment has only a single element available, this will be selected automatically.

   If there are no compartments available (a compartment must have an "unused" element in order to be treated as available), none will be listed. A compartment will automatically be generated for the protection device associated with the supply. The supply will be assigned to a default "Connector" element created with the automatically generated compartment. This can subsequently be replaced in the Supply Details - Compartments Tab - MCCs and Switchboards.

5. Click Assign. The selected supply is then displayed in the From field for the incomer.

To select a different supply for the incomer, or to unassign the current supply, click the button in the From field. The Assign Supply window is then displayed. As required, either select a different supply as described above, or click the Not Assigned button to unassign the supply.

The Ext. CS Template field is used to assign an External Cable Sizing template to an incomer. Refer toAllocate Cable Sizing Templates to Equipment for details.

To unassign a supply, click Unassign. A message will then be displayed requesting that the un-assignment be confirmed. Click Yes to continue.

To access details of a compartment on the Compartments tab, double-click on it. The Compartments tab is then displayed with the node of the selected compartment expanded. Refer to Supply Details - Compartments Tab - MCCs and Switchboards for details.

Details Tab for Horizontal Busbars - Couplers Section

Couplers linking the busbars of an MCC or Switchboard are created in the Coupler section of the Details tab.

To create a coupler or couplers linking the busbars of the MCC or Switchboard:

6. Click Couple. The Assign Load window is then displayed:

   

7. Select one of the busbar’s output voltages from the Output Voltage list. The output voltages for a busbar are viewed and specified using the Output Voltages Tab (Loads Assigned Tab - MCCs and Switchboards).

8. The window then lists the busbars with matching voltages. To create couplers linking these busbars, click their Select checkboxes, then click Assign.

9. A coupler is automatically assigned to a new compartment that it is automatically created for the coupler. The coupler will be assigned to a default "Connector" element created with the automatically generated compartments. This can subsequently be replaced in the Supply Details - Compartments Tab - MCCs and Switchboards.

10. The coupler compartments are then listed in the Coupler section:

    

To "decouple" a busbar from the current busbar, select the coupler compartment from the above list, and click Decouple.

A message is then displayed requesting that the user confirm that this is required. Click Yes to continue.

Details Tab for Vertical Busbars

The General section of the tab is the same as that for horizontal busbars.

The Frame Details section displays the frame name of the busbar in the Frame Name field. This defaults to the automatically generated busbar name, but may be edited here if required.

The tab also displays the compartment in which the element(s) connecting the vertical busbar to its horizontal busbar are located.
