When tracing and coloring a wire on a wiring diagram, coloring a wire(s) orange means that wire in the circuit is: a. Hot at all times. b. Switched to power. c. Ground. d. Variable.

## Step 1<br />In the context of wiring diagrams, different colors are used to represent different types of wires. The color orange is typically used to represent a wire that is "hot" at all times. This means that the wire is always carrying power, regardless of whether a switch is in the "on" or "off" position.<br />## Step 2<br />The other options provided, such as "switched to power", "ground", and "variable", are represented by different colors in wiring diagrams. For example, a wire that is "switched to power" is usually represented by a blue color, while a "ground" wire is represented by a green color.<br />## Step 3<br />Therefore, in this case, the correct answer is option 'a', which states that the wire is "hot at all times".
