One-Line Device Schedule Blocks

The One-Line Device Schedule Blocks commands allow you to customize the list of blocks available to create one-line device schedules on the drawing.

See the General Customization Commands section for more information about how the Edit Project List, Edit Master List, Copy Project List to Master, and Copy Master List to Project commands work.

The Edit Project List and Edit Master List commands open the One-Line Device Schedule Blocks dialog box.

Move Up: Press this button to move the selected block up in the list of blocks.

Move Down: Press this button to move the selected block down in the list of blocks.

New: Press this button to create a new block.

Delete: Press this button to delete the selected block. If the block is currently used by a record in the schedule, you will be asked if you want to replace the block in the schedule with another block.

One-Line Device Schedule Types

There are three different types of one-line device schedules available. Each type consists of a header block, a footer block, and one or more phase blocks. When a schedule is inserted, these blocks are inserted in the drawing to create the schedule.

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.

The different types are described further in the table below.

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. 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. 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. One block is inserted for each tap.

One-Line Device Schedule Block Settings

Description: The description column is a tree that lists each block group.

The black rows separate the blocks into the three main types.

The dark grey rows list each schedule. The value entered in the column is what will be displayed in the one-line device dialog boxes in the Schedule Block field.

The white rows and yellow rows list the various blocks that make up each schedule. The value displayed in each of these rows describes what the block will be used for in the schedule.

Block Name: For black and dark grey rows, this column is empty.

For white and yellow rows, this column is the block that is used for the item in the schedule.

Default One-Line Device Type: The schedule block that is used as the default for each type of one-line device. This column can be set in the dark grey columns. Only one schedule block can be chosen for each type of one-line device.
