Meter tails are a vital element in the domestic power supply. They connect the service head (where power enters the property) to the electricity meter, running through the main fuse boxes on the way. They are essential for new installations, and may occasionally need replacing in existing systems if worn. The 6181Y has double insulated tails and a PVC insulator with either blue or brown insulated copper core. It comes in a choice of conductor sizes and cable lengths and is suitable for surface wiring with light protection against mechanical damage.
