Abstract
The present disclosure provides exemplary embodiments of wiring device assemblies that include an electrical wiring device and electrical plug connector assembly which permits easy connection of electrical conductors to the electrical wiring device via the plug connector assembly. The wiring device assemblies are configured to operate at a common voltage rating and include keying features to ensure the electrical wiring devices are configured to mate with electrical plug connector assemblies rated for the same voltage. The keying features include a key and corresponding keyway used to prevent electrical plug connector assemblies rated for one voltage from being plugged into electrical wiring devices rated for a different voltage.
