6241B and 6241Y single core cables with earth are essential components for domestic electrical installations requiring an earth continuity conductor (CPC). Both cable types feature a single insulated live conductor combined with a bare copper earth conductor, all enclosed within an outer sheath. This design eliminates the need for separate earth bonding in lighting circuits and other applications.
