10 . The food waste disposer system of claim 9 , further comprising a coupler including an adjustable clamp feature through which the Romex/BX can be supported, wherein the food waste disposer is configured to support the coupler at least indirectly upon the housing.

11 . The food waste disposer system of claim 10 , further comprising a terminal cover, and a plurality of coupling elements, and a first orifice within the housing,

wherein the food waste disposer is configured to support the coupler directly upon the housing when the coupler is inserted within the orifice,

wherein first end portions of the first lead wires can be coupled to additional end portions of the additional lead wires at the coupling elements, and

wherein the terminal cover can be attached to the housing so as to enclose a cavity within the housing within which can be positioned the first end portions, the additional end portions, and the coupling elements.

12 . The food waste disposer system of claim 10 , further comprising an external wire box having a first orifice, and a plurality of coupling elements,

wherein the food waste disposer is configured to support the coupler indirectly upon the housing when the coupler is inserted within the orifice and the external wire box is attached to the housing,

wherein first end portions of the first lead wires can be coupled to additional end portions of the additional lead wires at the coupling elements, and

wherein the external wire box is attached to the housing so as to enclose a cavity formed by the external wire box and the housing within which can be positioned the first end portions, the additional end portions, and the coupling elements.

13 . The food waste disposer system of claim 1 , wherein the food waste disposer includes the first lead wires, which extend from the appliance inlet power cord connection structure or from the switch module.

14 . The food waste disposer system of claim 13 , wherein either the first lead wires extend from the appliance inlet power cord connection structure and the appliance inlet power cord connection structure is coupled to the switch module by way of an assembly, or the first lead wires extend from the appliance inlet power cord connection structure and the appliance inlet power cord connection structure is integrally formed with the switch module.
