Conductor Sizing Calculator Command

The Conductor Sizing Calculator reports the correct wire size for a given load, based on a single conductor and the length of travel.

To perform conductor sizing calculations:

1. Select AEC > Electrical > Conductor Sizing Calc.

The Conductor Sizing Calculator dialog box opens.

►    Click to show/hide the parameters.

Parameter	Description
Calculate	Select the type of calculation to perform
Phase Factor	Specifies the phase factor
Wire Properties	Enter the known conductor parameters; values returned by the calculation will are grayed
Type/Manuf.	Select the wire type or manufacturer
Size/Part Number	Select the wire size or the manufacturer part number
Sectional area of the wire, cmil	Enter the cross sectional area of the conductor wire in cmils
Approximate AWG	Enter the approximate AWG (American Wire Gauge) of the conductor
Resistance of conductor material at 75c	Enter the resistance of the conductor material at 75c
Temperature (c)	Enter the operating temperature in Celsius
Amps	Enter the amp rating
Length (ft.)	Enter the conductor length in feet
Type	Select whether the conductor type is Aluminum or Copper, and then enter an Alpha value if other than standard
Voltage Drop	Select whether the voltage drop is a Percentage or Absolute. If a percentage, enter the value.
Voltage	Enter the working voltage
Calculate	Performs the selected calculation

2. Select the type of calculation to perform, based on the current parameters, from the Calculate list.

Calculation	Description
Wire Size	Provides the sectional area of the wire (cmil) and the approximate AWG for wire sizes below 250 kcmil
Ohms/ft/cmil-ft	Calculates the resistance per sectional area of wire
Voltage Drop	Calculates the voltage drop across the length of the conductor, either as a percentage or absolute value
Phase Factor	Provides the phase factor value of the conductor
Voltage	Calculates the voltage value of the conductor
Ampacity	Determines the amp rating of the conductor
Length of Run	Calculates the allowable length of the conductor specified for the load given

3. Enter the required values in the fields. Fields where the result will be displayed are grayed. Some calculations require the selection of the wire type or manufacturer, as well as the wire size or part number. When all the required parameter values are complete, the Calculate button becomes available; click to perform the calculation.

4. The calculation results are displayed. Select another calculation to perform or click Close to exit.
