Set Looping Options

The Set Looping Options command is used to set options used when drawing circuit loops and homeruns.

To change the options used when drawing loops and homeruns, go to

DM Electrical->Circuiting and Homeruns->Set Looping Options

Looping Options Dialog Box

Circuiting and Homeruns--Looping Options dialog box

Draw Loops Between Circuited Devices: Controls whether loops are drawn between devices on the circuit and how circuit labels are displayed. This setting controls a number of related options.

Loops between devices can be turned on or off.

Circuit callouts on devices can be turned on or off. If they are on, they can be displayed with or without a panel name.

Circuit callouts on switches can be turned on or off separately from all other devices.

By turning the loops and the circuit callouts on, and inserting the loops on a non-plotting layer, it is possible to calculate branch circuit wire lengths while not displaying loops on the final printed drawing. The wire lengths are necessary to calculate voltage drop and display wire lengths in takeoffs.

The choices available for this setting are:

Yes, remove circuit callout, include all callouts on combined homeruns: Loops are drawn between devices on the circuit. Regular homeruns do not include circuit callouts on devices. Combined homeruns include circuit callouts on devices.
Yes, remove circuit callout, remove callouts with all circuits on combined homeruns: Loops are drawn between devices on the circuit. Regular homeruns and combined homeruns do not include circuit callouts on devices.
Yes, include panel in circuit callout (P-1), remove callouts from switches: Loops are drawn between devices on the circuit. Circuit callouts are included on all devices except for switches. The circuit callout include the panel name and the circuit number.
Yes, remove panel from circuit callout (1), remove callouts from switches: Loops are drawn between devices on the circuit. Circuit callouts are included on all devices except for switches. The circuit callout include the circuit number only and does not include the panel name.
No, include panel in circuit callout (P-1), remove callouts from switches: Loops are not drawn between devices on the circuit. Circuit callouts are included on all devices except for switches. The circuit callout include the panel name and the circuit number.
No, remove panel from circuit callout (1), remove callouts from switches: Loops are not drawn between devices on the circuit. Circuit callouts are included on all devices except for switches. The circuit callout include the circuit number only and does not include the panel name.
Yes, include panel in circuit callout (P-1), include callout on switches: Loops are drawn between devices on the circuit. Circuit callouts are included on all devices, including switches. The circuit callout include the panel name and the circuit number.
Yes, remove panel from circuit callout (1), include callouts on switches: Loops are drawn between devices on the circuit. Circuit callouts are included on all devices, including switches. The circuit callout include the circuit number only and does not include the panel name.
No, include panel in circuit callout (P-1), include callouts on switches: Loops are not drawn between devices on the circuit. Circuit callouts are included on all devices, including switches. The circuit callout include the panel name and the circuit number.
No, remove panel from circuit callout (1), include callouts on switches: Loops are not drawn between devices on the circuit. Circuit callouts are included on all devices, including switches. The circuit callout include the circuit number only and does not include the panel name.

Share Neutrals on Combined Homeruns: Whether or not neutrals are shared on combined homeruns.

Yes: Neutrals are shared on combined homeruns. This setting is not allowed if you are using the 2008 NEC.
No: Neutrals are not shared on combined homeruns.

To share neutrals in accordance with the 2008 NEC, a common trip for the circuits on the combined homerun is required.

One way to create a common trip for the circuits is to create three single-pole circuits and join them using the Change # of Poles button on the Circuiting dialog. See the Change # of Poles section for more information.

The other way to create a common trip for the circuits is to create a three-pole circuit and connect single-pole devices to the circuit using the Circuit to Phase button on the Circuiting dialog. See the Circuit to Phase section for more information.

Select Preferred Circuiting Direction: Whether or not the preferred circuiting angle prompt is used when drawing homeruns and loops.

Yes: The preferred circuiting angle prompt is used.
No: The preferred circuiting angle prompt is not used.

The preferred circuiting angle is used to guide which devices have loops drawn between them. When choosing which devices to connect, preference is given to devices in a line based upon the angle.

Select Loop Center Point: Whether or not the arc center point prompt is used when drawing homeruns and loops.

Yes: The arc center point prompt is used.
No: The arc center point prompt is not used.

All the loops that are inserted will arc away from the center point. The center point is used to help automatically draft the loops in an organized manner.

Voltage Drop Calculation Parameters: This section controls how the distance between devices is calculated. The values are stored in each circuit when the homerun is drawn. Changing the values does not change the stored values. Storing the values allows you to set the parameters correctly for one area of the building, draw your homeruns in that area, then change the values for another area of the building, and draw the homeruns in that other area.

These parameters might be changed for two different wings of a building at different angles, or for the interior of the building and the site.

Compute Conduit Length Orthogonal to Building Angle: Whether the circuit length is calculated based upon right angles to the building or a straight line distance.

If this is checked, the length is calculated based upon right angles to the building. This setting is commonly used inside a building, where the conduits have to be run in the walls. The angle of the walls is set in the Building Angle field.

If this is not checked, the length is calculated in a straight line between the two devices. This setting is commonly used on site plans, where the conduits do not have to follow the walls. This calculation minimizes the length of the circuit.

Building Angle: The angle of the building used to calculate the orthogonal circuit lengths. This value is used when Compute Conduit Length Orthogonal to Building Angle is checked.

Select Angle: Press this button to specify the Building Angle on the drawing. The dialog box will be closed. You will be prompted to specify the angle of the building by selecting two points.

Set building offset angle / <0>:

Specify second point:

The dialog box will be reopened and the specified angle will be set in the Building Angle field.

Loop to Same Circuit First on Combined Homeruns (Light Fixtures): Whether or not loops are drawn to the closest light fixture on any circuit or the closest light fixture on the same circuit on combined homeruns.

Loop to Same Circuit First on Combined Homeruns (Other Devices): Whether or not loops are drawn to the closest device on any circuit or the closest device on the same circuit on combined homeruns.
