Abstract: A dummy ground plug adapter is provided and comprises a base having two parallel, spaced-apart, rectangular slots formed therethrough and a dummy pin extending from a rear surface of the base. The base and dummy pin are formed from an electrically non-conductive material. The size and spacing of the slots and dummy grounding pin conform to the size and spacing of U.S. standard electrical three-prong plugs and outlets, allowing the prongs of a two-prong plug to slip through the slots and be inserted into a three-prong electrical outlet. The presence of the dummy grounding pin provides support and reduces the chance of the plug moving or loosening in the outlet.
