Isolated ground receptacles are required to be identified by what symbol?

Isolated ground receptacles are specifically identified by an orange triangle on the face of the receptacle. This identification is crucial because it indicates that the receptacle is designed to provide an isolated ground path, which helps reduce electromagnetic interference and enhance the performance of sensitive electronic equipment.

The orange triangle symbol is a standardized marker that alerts users and electricians to the distinctive grounding method used, ensuring that these receptacles are utilized correctly in applications that require minimized noise and improved signal integrity. Proper identification is essential for maintaining safety and functionality within electrical systems, particularly in commercial settings where sensitive electronics are deployed.
