This section describes the Change # of Poles button on the Circuiting dialog box and other dialog boxes. The Change # of Poles button is used to change the number of poles for a selected circuit.
To comply with NEC 2008 210.4b, this button can be used to merge three single-pole circuits into one three-pole circuit. If there are devices on the single-pole circuits, they will remain on the corresponding phases of the three-pole circuit. The circuits will now share a common neutral and a common trip.
When you press the Change # of Poles button, the Change Number of Poles dialog box will appear.
Circuit: The selected circuit.
Number of Poles: Select the number of poles for the circuit. Options that are not allowed for the current circuit will be disabled.
