The CP4 is a terminal block that employs Push-In connection technology and offers two points for connectivity. Prepared (lugged) wires can be inserted directly into the block without the aid of a screwdriver. Unprepared solid wires can also be connected instantly without any prior preparation. Wire removal is managed by using a screwdriver to depress the visible orange release button. For grounding applications, the CPG4 is a compatible ground terminal block sharing the exact same profile as the CP4.
