Why The Receptacle Outlet is Hard To Plug Into
New homes are required to have tamper proof receptacles, which are designed to keep children from sticking small objects in the slots; but end up also being adult-proof if you don’t know how they function. There is a shutter behind the hot and neutral slots that will not open to allow the prongs of a plug inside unless there is equal pressure from the prongs on both slots. So, if you try to insert the plug at an angle other than perpendicular to the receptacle or are trying to use a plug that has damaged or bent prongs, it will not open. Also, the mechanism can be a lttle stiff when new and might take a few in-out cycles to be easier to use.
Tamper resistant receptacles are recognizable by the “TR” embossed on the face at the plug insertion area, and the closure shutter that obstructs the opening in the slots just behind the face for the hot and neutral slots.
