What is the maximum voltage rating for enclosed cutouts in electrical circuits?

The maximum voltage rating for enclosed cutouts in electrical circuits is typically understood to be 7200 volts. This rating is essential for ensuring that the electrical components can safely handle the voltage without risk of failure or hazard.

Enclosed cutouts are designed to protect electrical circuits by providing a means to disconnect, isolate, or fuse the wiring at high voltage levels, and their specifications are critical for maintaining safety and functionality. The 7200 volts rating is commonly applied in utility distribution systems, allowing for effective operation in a range of settings, particularly in medium-voltage applications.

The other voltage ratings mentioned, such as 480 volts, 12000 volts, and 14400 volts, do not apply as standard maximum ratings for enclosed cutouts. While 480 volts is a common rating for lower voltage systems, 12000 and 14400 volts are typically utilized for higher voltage apparatus or lines, distinguishing them from the common specification for enclosed cutouts. Thus, 7200 volts represents the accepted maximum for these devices within their intended operational limits.
