Downgrade Equipment
The Replace tool also allows you to downgrade equipment during the replacement procedure. Downgrade means to move from a multiple phase to a single phase piece of equipment (or move from a three-phase to a two-phase). The following steps use this multiple-phase line as the downgrade example. As you can see in the Component Information pane, this conductor is currently an ABC phase conductor.
IMPORTANT: The Replace tool remembers the most recently used
CU, and that CU persists with the tool for additional use. To change
the CU, press F (or click your middle mouse button). This brings up
the CU Search.
-
On the Design tab, click the Replace
tool.
-
If this is the first time you have clicked the tool
in this design session, the CU Search automatically appears.
IMPORTANT: If this is not the first time you have clicked the tool, press F (or press your middle mouse button) to bring up the CU Search, if necessary. The tool remembers your most-recently used CU, which is displayed in the upper, right-hand corner of the application. If this is the CU you need, then you are good to go without having to search again.

If this is the first time you have clicked the tool
in this design session, the CU Search automatically appears.
-
If necessary, in the CU Search, find the install CU (in
this example, it is a single-phase conductor). After you find it,
double-click it.
-
Hover your cursor over the existing piece of equipment
that needs to be downgraded. Notice the tool tips display both the
phases that are going to be installed and the CU name of the install
CU.
TIP: Notice in the image above, the tool tip states an A phase + Neutral is going to be installed. If you need to change the phase, press the Tab key. Tab cycles through the phases (in this case, cycling through A, B, and C phase). -
Click the existing piece of equipment on the map. The install
CU is placed directly on the existing piece of equipment, and the
remove CU is offset so that you may see both simultaneously.
-
If the application could not find an appropriate remove
CU, a red
or green 
badge appears seeking additional input from you.

CU, a red

In the Component Information pane, you can toggle between
the new install CU that acts as the replacement and the previous piece
of equipment set for removal.
IMPORTANT: When downgrading, be mindful of downstream features that might become de-energized due to their upstream phase being removed.
