Enphase’s Q-TERM-3P-10 is used to cap round three-phase Q cables to make them watertight. Insert the cable through the cable gland and strip off a short length of the jacket. Insert the ends of the two copper conductors into the cap and screw into the cable gland. If you need to extend the cable with a connector at a later date, you can simply remove the cap and connect the extension. The product packaging contains one set of ten caps.
