What type of receptacle can replace a non-grounding-type receptacle when there is no grounding means?

A non-grounding-type receptacle can be replaced with another non-grounding-type receptacle when no grounding means is available because it maintains the same safety and functionality parameters of the original installation. This type of receptacle provides a simpler solution that does not require grounding, making it suitable for instances where grounding might be absent or impractical to install.

Grounding-type receptacles and outlets necessitate a grounding connection to operate safely and effectively; without such a connection, the installation would not comply with electrical codes and could present safety hazards. Additionally, a switch-type outlet is designed for specific applications centered around controlling power to devices rather than serving as a direct receptacle for plugging in equipment. Therefore, when considering replacements, a non-grounding-type receptacle is the most appropriate choice in the absence of a grounding system.
