Loads Tab (Loads Assigned Tab - MCCs and Switchboards)

This tab is used allocate loads to MCC and Switchboard busbars, and view details of those already assigned.

The tab only shows those busbar compartments with loads assigned to them. Busbar compartments without a load assigned are not displayed, nor are compartments for connectors from supplying items. All compartments can be viewed on the Compartments tab (see Supply Details - Compartments Tab - MCCs and Switchboards).

A load is automatically assigned to a new compartment that is automatically created for the load. The loads will be assigned to a default "Connector" element created with the automatically generated compartments. This can subsequently be replaced in the Compartments tab.

To assign loads to the busbar:

1. Click the Assign button. The Assign Load window is displayed:

   

2. To select the load or loads, first 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).

3. The loads that match the selected output voltage are then listed (including supplies that may be loads). Check the checkboxes in the Select column for the loads to be assigned, then click Assign.

4. If, with the addition of the selected loads, the sum of the rated power of the loads assigned to the supply would be greater than the supplies rated power, a warning message is displayed. For example:

   

5. Click Yes to assign the load anyway or No to cancel.

6. The loads are then assigned to the busbar.

7. Compartments are automatically generated for the protection devices associated with the loads. The loads 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.

Compartments are created with default values. These may subsequently be edited by double-clicking on the compartment/load row in the Loads tab. This opens the Compartments tab with the compartment selected. From the Compartments tab, editing facilities are available. Refer to Supply Details - Compartments Tab - MCCs and Switchboards for details.

To un-assign a load from a compartment or compartments, select the compartment or compartments in the Loads tab and click the Un-Assign button. A message is displayed requesting that the un-assignment be confirmed. Click Yes to continue.

To move a compartment to a different busbar, right-click on it. A list of the other busbars of the supply is then displayed. For example:

Click on the required busbar to complete the re-assignment.

Note:
From the Loads Assigned tab, 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.
