Isolated ground receptacles are permitted to be used only with what type of conductors?

Isolated ground receptacles are specifically designed to minimize electrical noise and provide a cleaner ground for sensitive electronic equipment. For these receptacles to function as intended, they must be connected with isolated equipment grounding conductors. Isolated equipment grounding conductors ensure that the ground path does not share any connection with other grounding systems or conductors, thus preventing ground loop interference that can compromise the performance of sensitive equipment.

The requirement for using isolated equipment grounding conductors guarantees that the isolation effectiveness is preserved, allowing devices connected to the isolated ground receptacles to operate with reduced electromagnetic interference. This is particularly important in environments like data centers or laboratories where precision and reliability are crucial.

Other types of conductors, such as standard or non-isolated equipment grounding conductors, do not provide this same level of isolation necessary for proper operation of the equipment connected to isolated ground receptacles, making them unsuitable for this specific application.
