There has been an increase in the installation of accessories that influence Insulation Resistance readings during testing such as sockets with integrated USB chargers and LED lighting being among the most common. These are also susceptible to damage during Insulation Resistance testing of Line to Neutral if precautions are not taken as it is simply impractical to remove these type of accessories after installation for testing.

The IR Link is a high strength magnetic link for Insulation Resistance testing of Line and Neutral to Earth on RCBO protected circuits that contain sensitive equipment.

The IR Link provides an alternative method to link line and neutral on any circuits protected by an RCBO or AFDD.
