LEAK PROTECTIVE PLUG

摘要

PROBLEM TO BE SOLVED: To provide a leak protective plug containing a protective earth plug allowing a stable protective earthing connection of a load side grounding wire for an outlet with earth electrode and also usable for an outlet without earth electrode. SOLUTION: The plug is provided with not only a pair of receiving plugs 2a/2b but also a protective earth plug 8 that can be matched with an earth electrode 51 installed in the outlet for grounding the load side grounding wire 9. The load side grounding wire 9 is connected to the protective earth plug 8 and the protective earth plug 8 is also pivotally-attached at its mounting end, being folded at the pivotally-attached part and encased in a storing recess 18 formed on an enclosure 1 so as to allow even an outlet without the earth electrode 51 to be usable as a bayonet plug.
