To Calculate Wire Sizes Using the Circuit Manager

When you check the wire sizes for circuits, the software calculates the sizes from the circuit rating and then compares them to the actual wire sizes in the circuit. You can then optionally resize undersized or oversized wires.

To check the wire sizes for circuits

1. In the Electrical workspace, select a wire and click Wire tabCircuits panelCircuit Manager drop-downCircuit Manager.
2. On the right pane of the Circuit Manager, select the circuit (or circuits) to check.

   Use SHIFT or CTRL to select multiple rows in the circuit view list to select multiple circuits. Choosing a panel on the left pane selects only the first circuit in the circuit list.

   Note: Before you can calculate wire sizes, you must add wire to the devices in the circuit. You must also set the type of conductor material for the wire style used, for example, copper or aluminium (for more information, see Configuring Styles for Wires).
3. Click (Calculate Wires).
4. In the Calculate Wire Sizes dialog box, specify a resizing option:

   If you want to…	then…
   compare wire sizes to calculated values without changing any sizes	select Check only.
   check wire sizes and have undersized wires resized automatically	select Change Under dimensioned.
   check wire sizes and have both undersized and oversized wires resized automatically	select Change All.

5. Click OK.

   If you chose to resize any wires, the wire sizes are updated in the right pane under Wires. If you chose only to check the wire sizes, the Calculate Wire Size - Results dialog box displays the results of the analysis.
