What is the main purpose of identifying screws with a green finish?

Identifying screws with a green finish serves a specific purpose in the context of electrical grounding. The green color is universally recognized in electrical systems as an indication of ground connections. This visual cue helps electricians and technicians quickly identify which screws are used for grounding, ensuring that safety measures are upheld during installation and maintenance.

Using screws with a designated color, like green, minimizes the risk of improper connections, thereby enhancing the overall safety of electrical systems. This consistent color coding is crucial in preventing miswirings that could lead to electrical faults or hazards. Understanding this coding system supports compliance with electrical standards and practices focused on safety.
