Abstract

Configurations for wire connectors and for electrical wiring devices that mate with or connect to the wire connectors are disclosed. The wire connectors have a housing and one or more contact assemblies positioned within the housing. Each contact assembly can receive and secure one or more wires, where the wires can be secured to or released from a contact assembly using a fastener accessible through an aperture in the housing.
