An appliance including an electrically-powered system, a primary power input, and an auxiliary power input is provided. The electrically-powered system is disposed within a housing. The primary power input is configured to supply electrical energy to the electrically-powered system. However, the housing generally hampers access to the primary power input after installation of the appliance. Therefore, the auxiliary power input, which is also configured to supply electrical energy to the electrically-powered system, is readily accessible relative to the primary power input after installation of the appliance.
