I was looking at the wiring in my parent's house and i noticed a couple of 3 prong outlets where the ground wire was only attatched to the metal receptacle box (by a screw) but not connected to the grounding screw of the outlet itself.
I don't believe, but i didn't test it, that there is any sort of 'self grounding clip' or anything which connects the grounding screw of the outlet to the box thus making the outlet grounded as well. But i guess i could have missed it.
Assuming that it resally is as i initially thought, box is grounded but outlet is not, is this a normal occurence at all or an example of wiring that needs to be fixed?
It is not a GFCI outlet nor is it protected by a GFCI outlet.
Thanks for any replies.
