Suitable for receiving a HO5VV-F 3 x 0.5-1.5mm² cable between 7mm minimum diameter and 10mm maximum diameter. Strip the cable outer sheath exposing the individual cable cores. Leaving sufficient space for the cables to be separated and fixed into the terminal strip connections. Strip each individual core back 10mm, exposing the cable.Ensure the dome cap is tightened enough that the cable is securely clamped and cannot move.
