Electrical connector assemblies, light bases with one or more electrical connector assemblies, and methods for connecting one or more electrical wires to one or more sheet-metal connectors are disclosed. An electrical connector assembly for an electrical distribution system is disclosed, which includes an electrically insulated housing with a wire-connection port and a blade-connection port. The wire-connection port is designed to receive an electrical wire, while the blade-connection port is designed to receive an electrically conductive blade. An electrical conductor is disposed within the housing, extending between the blade-connection and wire-connection ports. A first threadless fastener secures the wire in the wire-connection port and electrically couples the wire to the electrical conductor. A second threadless fastener secures the blade in the blade-connection port and electrically couples the blade to the electrical conductor. The wire-connection port may be configured to open and release the electrical wire without the use of a tool.
