The present disclosure provides cam activated wire termination assemblies for electrical wiring devices. The electrical wiring devices include a cover and a base. The base has a wire chamber supporting a wire termination assembly. The wire termination assembly includes a wire fastening member and a conductive member. The wire fastening member has a cam surface and is rotatable between an open position and a securing position. The conductive member is positioned in close proximity to the wire fastening member such that a gap is provided between the wire fastening member and the conductive member when the wire fastening member is in the open position. When the wire fastening member is rotated from the open position to the securing position, the cam surface rotates to reduce the size of the gap between the wire fastening member and the conductive member.
