What are the safety considerations when installing a GFCI outlet without a ground wire?

When installing a GFCI outlet without a ground wire, it is important to ensure that the outlet is properly labeled as "No Equipment Ground." This helps to alert users that the outlet does not have a physical ground connection. Additionally, it is crucial to test the GFCI outlet regularly to ensure it is functioning properly and providing the necessary protection against electrical shocks. It is recommended to consult a qualified electrician for proper installation and to follow all safety guidelines to prevent electrical hazards.
