The EC15 is blue and classified as terminal size A-D 2.5 - 10mm2, Max earth conductor 1 x 10mm2. Whereas the EC16 is green and classified as terminal size A-E 2.5 -16mm2, Max earth conductor 2 x 10mm2. Both BLUE and GREEN clamps are for corrosive or humid conditions. For your reference EC14 is red and classified as terminal size A-D 2.5 - 10mm2, Max earth conductor 1 x 10mm2, suitable for non corrosive dry atmosphere.
