Plan View and One-Line Diagram Block Settings

The Plan View and One-Line Diagram Block Settings dialog box is used to manage the blocks that represent the distribution equipment on the plan and one-line diagram. The information listed below is applicable to all distribution equipment except generators and low voltage panels unless otherwise indicated.

Elevation: The elevation of the distribution equipment. See the Elevation section for more information.

Select Block Based upon kVA: Whether the Plan View Block is automatically set based upon the kVA setting. Applies to transformers only.

Plan View

Plan View Block: The block used for the distribution equipment on the drawing. This list is based upon the settings in the Distribution Equipment Plan View Blocks command.

If the Plan View Block is set to a block with Custom Size set to Yes in the Distribution Equipment Plan View Blocks dialog box, the Depth, Width, and Height fields can be used to set the size of the equipment, in inches. These fields are disabled when a block with Custom Size set to No is selected.

Depth: The size of the equipment in the y direction, perpendicular to the rotation angle of the block.

Width: The size of the device in the x direction, parallel to the rotation angle of the block.

Height: The size of the device in the z direction.

One-Line Diagram

This section sets the blocks used for the distribution equipment and its connections on the one-line diagram. The Set Default button allows you to change the default for each block in the One-Line Diagram options section.

Insert Feeder to Distribution Equipment: Whether the upstream feeder for the distribution equipment is included on the one-line diagram.

Initial Block: The block used for the distribution equipment itself when it is generated. Changing this setting does not affect blocks already on the one-line diagram.

Initial Fed From: Whether the feeder is drawn to the top or bottom of the block when it is generated. Changing this setting does not affect blocks already on the one-line diagram.

Upstream OCP Block+: The block for the upstream OCP.<Use upstream distribution equipment OCP block> uses the same OCP block as the upstream distribution equipment. Changing this setting will affect blocks already on the one-line diagram.

Upstream OCP Block 2+: The block for the second upstream OCP. Applies to transfer switches and UPSs only.

Circuit OCP Block+: The block for the downstream OCP. Changing this setting will affect blocks already on the one-line diagram.

Main Disconnect Block: The block for the main disconnect. Only visible if Initial Block is set to <Custom Panel Box with Bus>. Not available if Main Disconnect Type is set to Main Lugs Only. Does not apply to transformers, transfer switches, or UPSs.
