"Wild leg" (120/240 center-tapped neutral delta configuration), the two end phases on the center-tapped winding provide 120 volts to neutral, but on the wild leg you will find nearly 208 volts to the neutral. If you see an orange wire in a panel, alarm bells should go off: You don’t want to wire a 120 VAC circuit across the wild 208 volt phase. | + | * Orange is the only ungrounded conductor specified by the NEC.
