Edit Project List

To customize the one line device schedule block list in your current project only, go to

The table below describes the various fields seen in the One Line Device Schedule Blocks dialog box.

Field	Sets
Description* *the different schedule types are described below	The appearance of the description depends on whether the block has been identified as a one line device, branch circuit device, or a feeder block. Double-click on the row to type in your desired description. This list contains a number of wire block descriptions that cannot be removed from the list; they are indicated with a gray background.
Block Name	This is the name of the file containing the block. Double-click on the row and select Browse to browse for the file you wish to use for any given block.
Default One Line Device Type	This column is used to specify which format will appear as the default format when creating new one line devices. Double-click on the row and select a type.

To create a new block, first you must have created a new block or have a block that has been unassigned. Press the New button, which will take you to the bottom of the table and add a new block. You may type in the desired description, set the block name, and set whether the block should be inserted to scale and can be rotated. When you have the block set, you may press OK to save the new block and close the One Line Device Schedule Blocks dialog box or press New to create another new block.

To delete a block, make sure the row of the block you wish to delete is highlighted. Then press the Delete button. Design Master will delete the selected block from the list.

It is possible to change the ordering of items in the list. To do so, select the row the of the block you wish to move and use the Move Up and Move Down buttons. You cannot move any given block from one type of schedule to another.

There are four different types of one line device schedules available using Design Master. Each type consists of a number of different blocks. When a schedule is inserted, these blocks are inserted in the drawing to create the schedule. All three of the new schedule types consist of a header block, a footer block, and one or more phase block.

The header block is inserted at the top of the schedule. It typically lists the one line device name and the relevant attributes of the devices, such as the voltage and bus amps.

The footer block is inserted at the bottom of the schedule. It typically includes all of the panel load totals. These can include totals by phase and the connected and calculated loads by load type.

All schedules have different blocks that are used for single-phase and three-phase one line devices. Typically, the only difference between these types of panels is that the single-phase schedules do not list any C phase loads; however, the phase blocks vary depending upon the type of schedule.

Schedule Type	Used For/Special Features
Odd on Left, Even on Right	This schedule type is to be used with panels. The odd circuits are listed on the left side of the schedule and the even circuits are listed on the right. For this schedule type there is a phase block for each phase of the schedule. Single-phase schedules have two phase blocks: A and B. Three-phase schedules have three phase block:, A, B, and C. Each phase block should include attributes for two circuits on it, one from the odd side of the panel and one from the right.
Odd on Top, even on Bottom	This schedule type is to be used with panels. The odd circuits are listed above the even circuits. For this schedule type there is a phase block for each phase of the schedule. There is also a block that is inserted after the last odd block and before the first even block. Single-phase schedules have two phase blocks: A and B. Three-phase schedules have three phase block:, A, B, and C. Each phase block should include attributes for only one circuit on it. The phase block will be used both above and below the divider for the odd and even circuits.
Taps	This schedule type is to be used for all one line devices other than panels. For this schedule type there is only one phase block for both single and three-phase schedules. One block is inserted for each tap.
Old Style (Single Block)	This schedule type is included for backwards-compatibility purposes only. The old style of schedules consisted of two blocks: one for single-phase and one for three-phase. Creating blocks to accommodate the different number of circuits or types in a schedules was cumbersome.
