This is where the importance of assigning a distribution system to your
electrical power equipment as it is placed comes into play. With the
equipment in place, you can easily create the relationship from component
to component. You can start at any component and connect to related
equipment upstream. You are able to work upstream only when building
distribution systems in Revit MEP. Because you will be assigning the
equipment that feeds a component, it is best to start at the branch circuit
panels and work your way upstream through the system. No wiring or
conduit needs to be modeled to establish the electrical connection between
two distribution components.
To create a distribution system, follow this general process:
1. Start by selecting one of your low-voltage branch circuit panels. If you
have not already done so, assign a distribution system to the panel from
the drop-down on the Options Bar. The Modify | Electrical Equipment
contextual tab appears on the ribbon. Because the connector in the
panel family is a power connection, a Power button appears in the
Create Systems panel of the tab. Click this button to create a power
circuit for the selected element. The active tab on the ribbon changes to
the Modify | Electrical Circuits contextual tab. Click the Select Panel
button to choose the equipment that feeds the selected component.
2. There are two ways you can select a panel: either by clicking the panel in
the drawing area or by selecting it by name from the Panel drop-down
list on the Options Bar. The drop-down makes it easy when the panel
you need is not shown in the current view. The only components that
show up in the drop-down or are available for selection in the drawing
area are those that have connectors that match the distribution system
of the selected component. This includes any panel or equipment in
your project, not just in the current view.
In
Figure 13.26
,
a power circuit is created for panel LA. Notice that
transformer TA is the only equipment available to feed the selected
panel, because the connector properties of panel LA match up with the
settings of the distribution system for the secondary side of the
transformer.
