How is an isolated grounding-type receptacle identified?

An isolated grounding-type receptacle is identified by an orange triangle on the receptacle. This identification is important because it signifies that the receptacle is designed to provide a separate, isolated ground connection. This is crucial in instances where sensitive electronic equipment is used, as it helps reduce electrical noise and provides a dedicated path for stray currents, enhancing safety and performance.

The orange triangle serves as a visual cue for electricians and technicians, indicating that this specific receptacle type should be treated differently than standard grounding receptacles, which might not offer the same advantages in critical applications. By recognizing this distinctive marking, professionals can ensure proper installation and maintenance practices are followed, ensuring compliance with electrical codes and the safety of electrical systems.
