Executive summary
IPCs have been developed as an effective way of making a connection on the overhead distribution network, and in some consumer lighting systems. In principle, an IPC connector could provide a safe and reliable connection and, at first glance, they appear to offer a solution for making easy and economic connections to consumer meter tails.
However, they must be used in accordance with the relevant product and installation standards. The use of IPCs with consumer’s meter tails is outside the scope of the standard for overhead distribution connectors, BS EN 50483-4:2009 and until such time as they have been tested and are covered in a suitable British or Harmonized Standard such as BS EN 61238-1-2:2019, and the ongoing security of pre-existing connections is assured, it is not considered acceptable to use them on the consumer’s side of the installation. To do so results in an installation that presents a high risk of failure or harm and does not comply with recognised standards.
What is an insulation piercing connector?
IPCs are similar to line taps used for overhead lines, enabling a branch connection to be made to an existing cable without stripping the insulation of the cable, and using a shear head bolt to ensure it is tightened to the correct torque. This is well established technology in some industries and prevalent in the distribution network but not generally used on the consumer’s side of the installation.
