The item is used in connecting a light fitting or other device to the network supplying it. The T-connector has a 0,4 m or 2,5 m long, halogen free, stranded cable. The free end of the cable is stripped, which will be wired to the connection coupler in the device. The T-connector is fed with a NAC32S.W -coupler (or with an prefabricated cableset). The installation continues from the T-connector to the next device with a NAC31S.W (or with an installation-ready cableset).
