Realize that for decades there used to be a far more treacherous version of grounding adapter—it had a ‘flying’ ground lead, that could contact the ungroudned or ”hot” blade of the adapter and unintentionally energize an appliance enclosure.
It is fortunate that GFCIs are permitted to be installed on 2-wire (ungrounded) breach circuits.
Maybe Canadian members can verify that the pictured adapter was NEVER permitted by CSA?
