Electrical One-line
The PXG helps you create diagrams on a One-line through a feature called "Auto-draw." Auto-draw dramatically
reduces the time it takes to create an electrical One-line diagram. It not only sets up the starting point for your
One-line diagram, it helps you connect devices in the diagram as you edit. How Auto-draw behaves is based on the
following configuration settings:
Number of Sources
If you don't want to automatically add a source, select Zero Sources. If you choose One source, Auto-Draw adds a
source symbol in the upper left and connects all devices to this. Choose Two sources and a second source symbol
appears in the upper right. Once sources are created, you can place them anywhere you like. Devices will
automatically connect to the closest source. If you've chosen Zero Sources, you can still add lines and symbols to
the page.
Tie Breaker Symbol
You can add a tie breaker to your diagram if you have two power sources. This is automatically centered on a
horizontal tie line in the upper half of your one-line diagram. Choosing Low or Med (Medium) Voltage changes the
symbol appropriately. Choosing blank provides a place to drag an actual breaker device into that position. You can
also drag any of the colored medium voltage breaker symbols there.
