What is a key safety measure to take when working with electrical systems?

Work with rubber gloves

Use insulated tools

Disconnect power before performing maintenance

A crucial safety measure when working with electrical systems is to disconnect power before performing maintenance. This step is essential because it significantly reduces the risk of electric shock or electrocution while you are working. Ensuring that the system is de-energized creates a safe environment for troubleshooting or repairing, as it eliminates the possibility of accidental contact with live circuits.

Additionally, while wearing rubber gloves and using insulated tools are important practices to further enhance safety, they do not provide complete protection if the power remains on. Wearing safety glasses is generally a good practice for protecting your eyes from debris, but it does not address electrical hazards directly. Thus, disconnecting power stands as the primary and most effective precaution to safeguard against electrical incidents while conducting maintenance.
