Assign Supplies from the General Tab

If the supply is of an equipment type which can itself be supplied (for example, an MCC, Junction Box, Distribution Board, Transformer, Switchboard, UPS, Miscellaneous Supply or Variable Speed Drive), the General tab includes additional facilities for displaying the supply:

For an MCC, Distribution Board or Switchboard, supplies are assigned to each incomer using the Details tab of the Loads Assigned/Winding tab of the supply. Refer to Supply Details - Loads Assigned Tab - MCCs and Switchboards and Supply Details - Loads Assigned Tab - Distribution Boards.

For a Transformer, UPS, Miscellaneous Supply or Variable Speed Drive, to assign a supply:

2. If a supply or supplies have already been assigned, a message is displayed requesting confirmation that additional supplies are to be assigned. Click Yes to continue.

   Note:
   Loads and their supplies can be designated when creating a Key One Line diagram. Refer to Create Content of Key One Line Diagrams for details.

   Note:
   The voltage of a supply cannot be changed once a supply is allocated to it. The supply must first be unassigned from the supply.

3. 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.

4. In the case of MCCs and switchboards, select a compartment from the From Compartment list.

5. Depending the on the supply type, the From Element/Circuit column will display the default circuit (for distribution boards) or available compartment element (for MCCs and switchboards) for each supply (if they have been defined).

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

7. 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.

8. 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).

10. To assign additional supplies, click the Assign button again and proceed as described above.

11. The (current) fed item is automatically assigned to a new automatically created compartment.

Un-Assign Supplies

For a Junction Box, Transformer, UPS, Miscellaneous Supply or Variable Speed Drive, to unassign a supply or supplies from a supply, select them in the Supplied From section on the General tab and click Un-Assign. A message is displayed asking that the un-assignment be confirmed. Click Yes to continue.
