the same model. Aligning and locking a component to a linked component
causes a constraint error if the linked component moves and the linked file
is reloaded.
Another example of an electrical design component that does not have
any physical geometry is a motor connection. A motor connection can be
represented in the electrical model in the same way an equipment
connection can be represented. The electrical data for the motor can come
from either the equipment family or the symbol family used to represent the
equipment.
Disconnect Switches
Disconnect switches may not require model components, depending on
their use and who is to provide them for construction. Certain types of
equipment come with a means of disconnect built into them, while others
require that a disconnect switch be provided in addition to the equipment.
A disconnect switch that the electrical contractor is required to provide
should be included as a model component in order to coordinate location
andspacerequirements. Face-hostedfamiliesshouldbeused,becausethese
types of disconnect switches may be mounted on walls or directly to the
equipment that they serve. The disconnect switch family that comes with
Revit MEP 2015 has several types based on voltage and rating. This family
is found in the
Electrical/MEP/Electric Power/Terminals
folder
of the library that installs with the software. The family is categorized as
electrical equipment; therefore, using a symbol to represent this family
is difficult because face-hosted electrical equipment does not contain the
parameter to maintain annotation orientation. Therefore, each disconnect
switch displays at its actual size based on the type chosen, as shown in
