Figure 14.2 Wire size settings
The Correction Factor section of the Electrical Settings dialog box is for
setting a correction factor based on temperature to be used in load
calculations. You can set correction factors for different wire temperature
ratings and materials. The Ground Conductors section allows you to set the
equipment grounding conductor size for different ampacities of different
wire materials. So, you have the ability to control several factors that
determine the wire sizes that are calculated for your circuits.
In the Wiring Types section of the Electrical Settings dialog box, you can
create different types of wires for different uses. By creating different wire
types, you have the ability to assign all the desired settings to a type, and as
with component families, you can switch between wire types in the model.
Creating wire types also provides you with an easy way to control the
visibility of certain wires by using a view filter. You can give your wire types
unique names that define their use or some characteristic about them. You
can set the material, temperature rating, and insulation used by a wire type.
You can also set the maximum wire size for a type. If a circuit requires
a larger wire size than the maximum, parallel sets of wires that do not
exceed the maximum size are automatically created to accommodate the
load. You can establish whether your wire type requires a neutral conductor
and, if so, set the neutral size equal to the hot conductor size or set it as
an unbalanced circuit. After the neutral conductor is sized, the value you
input for the neutral multiplier is assigned. Although there are conduit tools
for modeling, there is no connection between the conduit or cable tray and
circuits yet. It is necessary to use these settings to establish the conduit
