Red Seal Industrial Electrician Practice Exam

Which of the following is not a standard color for ground conductors in Canada?

1. Green

2. Red

3. Bare

4. Yellow

The correct answer is: Red

In Canada, the standard colors for ground conductors are green for insulated conductors, bare for uninsulated conductors, and sometimes, the use of green with yellow stripes is also acceptable. The primary purpose of these color codes is to ensure safety and consistency, allowing electricians and anyone working with electrical systems to easily identify ground conductors. The color red, while commonly used for other purposes such as phase conductors in three-phase systems, is not designated as a color for ground conductors. Thus, choosing red highlights that it does not conform to the standard color coding for grounding in Canada, making it the correct choice in this context. Yellow is typically used in Canada for second-phase conductors and is also not associated with grounding. Understanding these color codes is essential for safety and compliance with electrical standards, as misidentifying conductor functions can lead to hazardous situations.
