4 Under Neutral, specify property values for the neutral wires:
■
Specify whether the properties of the neutral wires should match those of the conductors:
Then… If you want to…
click Match hot, and for Size of hot in %, enter the size of the neutral
wires expressed as a percentage of the size of the conductors. use the property values specified
for the conductors
click Specify neutral, and then specify values for Material, for Insulation,
and for Temp. Rating. specify property values for the
neutral wires
5 Under Ground and under Isolated Ground, specify property values for the ground wires:
Specifying Annotation for Wire Styles
When you draw a wire, you can select a style for the wire on the Properties palette. The style determines the
annotation properties for the wire, such as the tick marks to use for conductor, neutral, and ground wiring;
the symbol to use for home run arrows; and how to display connections.
NOTE Wire tick marks are always displayed in plan views unless you turn them off through (Edit Display
Properties) on the Display Properties tab in the Style Manager or the Wire Style Properties dialog. For more
information, see
Configuring the Display Properties of a Style on page 610.
The style of a wire also determines how crossing wires are displayed. You can display crossing wires as is, or
with an overlap or a break of a specific width.
If you select the overlap style or break style, you must also specify a corresponding priority value. In a
drawing, if 2 crossing wires have the same priority value in their corresponding styles, the order in which
the wires were drawn determines which wire displays the overlap or break. If the priority values are different,
the priority values determine this. Refer to the following table for more information.
Then... And if the priority values of
the 2 wires are... If the crossing style of
the 2 wires is...
the wire drawn second displays the overlap. the same overlap
the wire drawn first displays the break. the same break
the wire drawn second determines the crossing style to
use. If the style is overlap, the wire drawn second displays the same mixed (one is overlap, and
the other is break)
the overlap. If the style is break, the wire drawn first displays
the break.
the wire with the lower priority value displays the overlap. different overlap
the wire with the higher priority value displays the break. different break
the wire with the lower priority value determines the
crossing style to use. If the style is overlap, the wire with different mixed (one is overlap, and
the other is break)
the lower priority value displays the overlap. If the style is
break, the wire with the higher priority value displays the
break.
