Surge protector grounded light is off

The grounded indicator reports the outlet-grounding condition on supported models. If it is off, do not infer the receptacle is correctly grounded from the strip alone; verify the outlet with an appropriate plug-in tester and hand wiring correction to a licensed electrician.

Where to stop. Swapping a plug-in surge strip is homeowner-safe. If the "Grounded" light is off, the receptacle itself may be ungrounded or miswired — confirm with a plug-in tester, and because correcting house wiring means live conductors, if a tester shows an open ground have a licensed electrician verify the outlet.
