What is a critical step in the setup of electrical systems to enhance safety?

Ensuring all circuits are properly grounded is a fundamental safety measure in the setup of electrical systems. Grounding provides a path for electrical current to follow in the event of a fault, such as a short circuit. This helps prevent electrical shocks, reduces the risk of equipment damage, and minimizes the potential for fire hazards. Proper grounding also stabilizes voltage levels within the electrical system, enhancing the overall reliability and safety of the electrical installation.

Good grounding practices are mandated by the National Electrical Code (NEC) to ensure that all electrical systems operate safely. By following these guidelines, electricians can help prevent accidents and protect both equipment and individuals from electrical hazards.
