What can a non-grounding-type receptacle be replaced with if there's no grounding means in the receptacle outlet box?

A non-grounding-type receptacle can be safely replaced with another non-grounding-type receptacle when there is no grounding means available in the receptacle outlet box. This is consistent with electrical safety standards and practices, which prioritize maintaining the integrity of the grounding system.

If a grounding-type receptacle were to be installed in an outlet without a proper grounding means, it could create a hazardous condition. The grounding feature of such a receptacle is intended to provide safety by directing any fault current away from a person and to the ground. Without a functional grounding path, there would be an increased risk of electrical shock or fire in case of a fault.

Choosing to replace a receptacle with one of the same type (non-grounding) ensures compliance with safety codes while allowing for continued use of the outlet without introducing potential safety hazards associated with improper grounding.
