having a third (grounding) pin. This plug will fit into only a grounding-
type power outlet. This is a safety feature. If you are unable to insert
the plug into the outlet, contact your electrician to replace your
obsolete outlet. Do not defeat the purpose of the grounding-type plug,
by using an adapter.
