These sets allow direct connection safely to bare conductors and provide a safe method for electrical flow to return down to earth.
The kits consist of three contact clamps attached via flexible copper cable to an earthed trifurcation connector. This connector is then attached by silicone cable directly to an earthing clamp that is designed for attachment to a designated earthing point.
The systems are IEC-61230 compliant and ship as standard with a case.
Three different variations of these kits are available that come with different items:
