Abstract: An electrical socket shim assembly for inhibiting an electrical plug from freely moving in an electrical socket includes a plurality of shims and each of the shims has a first lateral side and a second lateral side. Moreover, each of the shims is concavely arcuate between the first lateral side and the second lateral side thereby facilitating each of the shims to be positioned between a corresponding circular electrical plug and a corresponding circular electrical socket. Each of the shims has a unique thickness with respect to each other for occupying a unique amount of space in the corresponding circular electrical socket. A plurality of tabs is provided and each of the tabs is coupled to a respective one of the shims. Each of the tabs is secured to a support when the respective shim is positioned between the corresponding circular electrical plug in the corresponding circular electrical socket. In this way the respective shim is inhibited from being removed from the corresponding electrical socket.
