Is it true that transient voltage risk exists even in CAT I sources?

The assertion that transient voltage risk exists even in CAT I sources is accurate. CAT I environments refer to low-voltage applications, typically with limited exposure to overvoltages, such as those found on electronic devices and their associated circuitry. However, transient voltages can still occur due to various factors such as inductive kickback from motors, lightning strikes, or even switching operations in the electrical system.

Even though CAT I applications are generally perceived to have lower voltage levels, the potential for sudden voltage spikes remains. These transients can lead to damage of sensitive equipment and pose safety hazards to personnel handling the instruments. Therefore, it is crucial to always be vigilant and employ proper safety practices, even in environments classified as CAT I.

Other options may imply that transient voltages are not a concern in CAT I settings, which could lead to complacency and increased risk during electrical measurements or troubleshooting. Emphasizing the presence of transient voltage risk reinforces the need for caution and adherence to safety protocols across all categories of electrical environments.
