Adjust Wire Sizes

Although wiring for a circuit is automatically sized according to load and voltage drop, you can adjust the size by changing the circuit rating.

1. Highlight one or more electrical devices or lighting fixtures in the circuit, and press TAB.

   If you have created permanent wiring, press TAB twice to highlight the circuit.

2. Click Electrical Circuits tabProperties panel Properties.
3. On the Properties palette, scroll down to Wire Size, and notice that the wire sizes cannot be edited.

   Wire Size parameters display, from left to right as hot conductors, neutral conductors, and ground conductors using the format: number of conductors - size.

   For example 1-#12, describes a single #12 conductor.

   You adjust the wire sizes by changing the value for the circuit Rating parameter.

4. Scroll up to the Rating parameter, and enter a value for the circuit amperage.

   The wire sizes are automatically updated.
