How do you test if a 2 prong outlet is grounded?
To find out whether the metal housing is grounded, purchase a circuit tester. Insert one of the tester’s prongs into the hot slot (the shorter slot in the outlet). Put the other prong onto a screw holding the cover plate. If the tester lights up, it means the metal box is grounded.
