In industrial systems, voltage levels are standardized based on the application and type of equipment used. The typical voltages for industrial applications are usually higher and cater to three-phase power requirements, which are more prevalent in larger systems.

The 600V standard is common for a variety of industrial applications, particularly for motors and heavy machinery. Similarly, 347V is often used in Canada for commercial lighting applications, and 240/415V can refer to systems utilized in different parts of the world for three-phase power distribution.

In contrast, 120V is primarily a residential voltage level. While it can appear in some industrial contexts, it is not representative of the typical voltage levels used in larger industrial systems compared to the other options listed. Therefore, 120V stands out as an atypical voltage for industrial environments, making it the correct answer in this scenario.
