This option directs Circuit Builder to use a de-rating factor for an elevated
ambient temperature. These values are defined in the electrical standards
database file.
15 Select 36~40C from the drop-down list.
The de-rating factor is extracted from the electrical standards database
file and entered in the dialog box. The wire size grid is adjusted based on
the new total de-rating factor. Based on this de-rating factor the minimum
wire size can change.
16 Select the Run distance option.
This option directs Circuit Builder to consider the length of the wire run
in the voltage drop calculation. Additional columns display in the wire
selection grid showing Voltage drop, wire KW loss, and wire loss cost
estimate.
17 Select 200 from the drop-down list.
Circuit Builder displays parallel energy loss calculations to allow you to
make better green design decisions. For example, you can oversize the
conductors for a motor to reduce conductor heating losses. It results in
a higher initial cost, material, and installation labor, which is recovered
many times over in reduced energy losses in the wiring during the life of
the motor.
18 Select a wire size in the grid based on the values shown.
19 Select a Grounding conductor size. The minimum size is preselected based
on the load of the motor.
20 Click OK.
21 Select Circuit Elements: Motor Symbol.
22
In the Setup & Annotations: Motor section, select the Browse
button.
The Parts catalog dialog box displays.
23 Select a catalog value and click OK.
NOTE Circuit Builder does not preselect the catalog based on the parameters
entered previously.
