Isolated ground receptacles are specifically designed to minimize electrical noise and enhance the performance of sensitive electronic equipment. The identification of these receptacles is standardized for clarity and safety. An orange triangle is used to denote isolated ground receptacles, signifying that the outlet is equipped with a separate grounding path to reduce electronic interference and improve safety.

The use of a distinct marking such as the orange triangle ensures that electrical professionals and users can easily recognize these specialized receptacles, differentiating them from standard outlets and highlighting their unique function. This identification helps prevent potential miswiring or improper use, promoting safer installation practices and equipment operation in environments where electrical noise is a concern, such as data centers or medical facilities.
