6241Y/6242Y/ 6243Y to BS 6004
Application and Description
6241Y/6242Y/ 6243Y to BS 6004 cables are suitable for fixed installation in dry or damp premises on walls,
boards or trays, in channels or embedded in plaster. They should be laid in conduit or trunking where mechanical
protection is required.
