Which color signifies the lowest strength in power loads?

1. Brown

2. Green

3. Grey

4. Purple

The correct answer is: Grey

The color that signifies the lowest strength in power loads is grey. In electrical and power distribution systems, color codes are often used to categorize different voltage levels or power strengths. Grey typically denotes a lower voltage or less strength in comparison to other colors, making it an important distinction for safety and proper handling. Understanding color codes is essential in practical applications for millwrights, as using the appropriate color ensures that workers can easily identify and manage different electrical loads. This can help prevent errors in operations, reduce the risk of workplace accidents, and promote effective communication among team members regarding power levels. Therefore, recognizing grey as the color associated with the lowest strength plays a pivotal role in maintaining safety standards and operational efficiency.
