Wiring

When Wiring is selected in the left pane of the Electrical Settings dialog, the right pane contains the wiring table.

The settings in the wiring table determine how Revit calculates wire sizing and how wires are displayed in the electrical system plans in your project.

• Ambient Temperature - Specifies the temperature of the environment in which the wiring will exist.
• Gap of Wiring Crossing - Specifies the width of the gap used to display non-connected wires that cross, as shown.
  
• Wire Tick Marks - Specifies the style of tick mark that displays for Hot Conductor, Ground Conductor, and Neutral Conductor.

  Revit provides four tick mark styles, as shown:

  Short Wire Tick Mark
  Circle Wire Tick Mark
  Hook Wire Tick Mark
  Long Wire Tick Mark

  To load a tick mark family

  1. Click Insert tabLoad from Library panel (Load Family).
  2. In the Open dialog, navigate to AnnotationsElectricalTick Marks.
  3. Select one or more tick mark family files, and click Open.

  You can assign a different style to each conductor.

  Click the Value column, click , and select a tick mark style.

  You can use the Family Editor to customize an existing tick mark or create additional tick marks.

• Slanted Line across Tick Marks - Specifies whether to display the tick mark for the ground conductor as a diagonal line that crosses the tick marks for the other conductors, as shown.
  

  Click the Value column, click , and select Yes to apply this feature to tick marks. If you select no, the tick mark specified for the ground conductor displays.

• Show Tick Marks - Specifies whether to always hide tick marks, always show them, or show them for home runs only.
• Max Voltage Drop For Branch Circuit Wire Sizing - Specifies the percentage for the maximum voltage drop allowed for branch circuits.
• Max Voltage Drop For Feeder Circuit Wire Sizing - Specifies the percentage for the maximum voltage drop allowed for feeder circuits.
• Arrow for Multi-Circuits Home Run - Specifies the whether a single arrow or multiple arrows display on all circuit wires or the end wire only.
• Home Run Arrow Style - Specifies the style for the home run arrow, including the arrow angle and size.
