Feeders for Current One-Line Diagram Users

Monday, November 30th, 2015

New commands and features have been added to make it easier to arrange the feeders on your one-line diagram.

The first improvement you will notice is that when you generate your one-line diagram or insert a single piece of distribution equipment, the initial routing of the feeder is much improved. The starting point is no longer the very end of the bus on the upstream panel. You should have less need to immediately redraw every single feeder that is inserted.

Feeder Breaks

When feeders cross, a break is automatically inserted. The Wire break block option is used for the appearance of the break. You cannot move or modify these breaks.

The breaks are updated when the Update One-Line Diagram command is run. They do not automatically update as you modify your feeders. Inserting the breaks takes a little bit of time. Updating them with every change to your feeders is too slow to work in actual practice.

Swap Feeder

Use the Swap Feeder command to switch the location of two feeders. Most often this command is used on two feeders coming from the same panel. Changes to the rest of the diagram have created a situation where you need to rearrange the order of the feeders coming off the bus. This command allows you to easily move them around without losing your spacing or general routing.

You select two parallel feeder segments on different feeders. The location of the feeder segments will be swapped with each other. The swap will often cause the two feeders to cross each other. The command will follow the feeders and swap segments until they no longer cross.

Redraw Feeder

There are times when the feeder on the drawing is too wrong to try to fix. Getting it to look right by adding and removing segments and adjusting the location using grips is going to be too time-consuming. In these cases, you should use the Redraw Feeder command to insert the feeder from scratch. You will get to specify the location of the feeder from start to finish and new locations for the blocks and labels on the feeder.

You can draw the feeder from the upstream or the downstream distribution equipment. If you select the feeder, you initially are set to draw from the upstream distribution equipment. If you select a piece of distribution equipment, you will redraw the feeder to that equipment starting from the equipment , which will be the downstream equipment. In either case, you can use the command-line options to reverse the direction you are drawing.

When you are drawing from the upstream distribution equipment to the downstream distribution equipment, you have the option at the command line to Finish the feeder. This option will insert an end to the feeder that connects to downstream distribution equipment at the appropriate connection point. It saves you from having to line up the end of the feeder.

Node and Tangent Osnaps

Feeders use the Node and Tangent osnaps for special purposes. These osnaps are especially helpful when redrawing a feeder.

The Node osnap will snap to a point that is offset from the start or the end of the feeder. The distance is equal to the Feeder offset distance in the Options command. This snap is useful for arranging sets of feeders coming from a single panel. To turn on the Node osnap while running a command, type NOD at the command line.

The Tangent osnap will snap to a perpendicular point that is offset from the feeder. The distance is equal to the Feeder offset distance in the Options command. This snap is useful when running a feeder parallel to a feeder that is already inserted on the drawing. To turn on the Tangent osnap while running a command, type TAN at the command line.

Offset Feeder

The Offset Feeder command allows you to easily space your feeders equally apart. The distance is equal to the Feeder offset distance in the Options command.

You first select the feeder segment that is in the right location. Then you select the feeder segment that you want to move. Finally you select a side of the first segment you selected. The second segment will then be moved.

You have the option to continue to select feeder segments. Each segment will then be offset from the last segment that was moved. You will not be prompted to select a side again. The feeders will continue to offset to the same side.

Align Feeder

Use the Align Feeder command to line two feeder segments up with each other. It is useful when you have two parallel feeders that need to turn in different directions and when you have a series of feeders connecting distribution equipment.

You first select the feeder segment that is in the right location. Then you select the feeder segment that you want to move. The second segment is moved so that it is on the same line as the first feeder segment.
