Single-Phase Panel Schedules

You can select to use single-phase panel schedules in the File Properties (for a specific database file) or in File Locations (for all newly created files). See Setting File Properties and File Locations Tab for more information.

Panel Schedule 1PH-3W Templates

The template for 1PH-3W is similar to the standard panel template, except:

  • The grid has only 2 columns for load values and the columns are labeled L1 and L2. The columns show loads from phase A and B, B and C, or A and C depending on the phase of the panel.
  • The rows are labeled 1,3,5,7, and so on for the left side and 2,4,6,8, and so on for the right side. If you enter load data in the standard diagonal arrangement on the diagonal, this means that for an AB phase type, 1=A, 2=B, 3=A, 4=B, and so on.
  • The Code Factors table has only two columns for the loads and the columns are labeled VA(L1) and VA(L2). The columns show loads from phases A and B, B and C, or A and C, depending on the phase of the panel.

Note: The 1PH-3W template is also used for 1PH-2W panels that display 2 columns.

Panel Schedule 1PH-2W Templates

The template for 1PH-2W is similar to the standard panel template, except:

  • The grid has only 1 column for load values and the column is labeled Load. The column shows loads from A or B or C depending on the phase type of the panel.
  • The Code Factors table has only one column for the load. The column is labeled VA and shows loads from A or B or C, depending on the phase type of the panel.

Panel Schedule Variables for Single-Phase Templates

There are new panel schedule variables that support single-phase templates. The new variables use the phase number instead of the phase name and are as follows:

  • %Phase1Total%
  • %Phase2Total%
  • %Phase3Total%

Note: For 3-phase panel schedule templates, these new variables replace %PhaseATotal%, %PhaseBTotal%, and %PhaseCTotal%. However, the old variables remain available in the software to support older templates.

In addition to the above, the variable %Voltage% has different behavior depending on the phase and service of the panel.

  • If the panel is 3PH (regardless of the service), the variable displays both the base kV and LG voltage. The LG voltage is the base kV divided by SQRT3.
  • If the panel is 1PH and the service is 1PH-3W, the variable displays both the base kV and LG. The LG voltage is the base kV divided by 2.
  • If the panel is 1PH and the service is 1PH-2W, the displays only the base kV.
