True or False: It is necessary to shut off the power before replacing a circuit protection device in an energized system.

The statement is true; it is necessary to shut off the power before replacing a circuit protection device in an energized system. When working on electrical systems, safety must always be the top priority. Replacing a circuit protection device, such as a fuse or circuit breaker, while the system is energized poses a significant risk of electrical shock or arcing, which can lead to injuries or equipment damage.

By ensuring that the power is turned off before beginning any work, you create a safe environment for yourself and anyone around you. This practice aligns with the lockout/tagout procedures that are an essential part of maintaining safety in electrical work. Furthermore, many electrical codes and standards emphasize the importance of de-energizing circuits before performing maintenance or inspection to avoid hazardous situations.

Taking these precautions helps ensure a safer workplace and reduces the likelihood of accidents during maintenance activities.
