Are equipment grounding conductors installed in raceways for isolated ground receptacles required to be continuous?

The requirement for equipment grounding conductors (EGCs) installed in raceways for isolated ground receptacles is that they must be continuous. This continuous grounding is crucial for ensuring safety and proper functioning of the electrical system.

Isolated ground receptacles typically require a dedicated equipment grounding path to reduce the introduction of noise and to protect sensitive electronic equipment. If the EGC is not continuous, it may create potential issues such as increased impedance, which can lead to improper operation of the connected devices and safety hazards. The continuity of the EGC is therefore essential to fulfill these safety functions and to comply with the National Electrical Code (NEC) requirements.

By ensuring that the grounding conductors are continuous, any fault current can be effectively conducted back to the disconnect or breaker, providing necessary protection for the system. This is a critical aspect of electrical installations, particularly in environments where sensitive electronic devices are used. Consequently, the assertion that such conductors are required to be continuous is indeed accurate based on the standards governing electrical installations.
