Equipotential Clamps

Equipotential Earth Clamps (EEC) are used when the equipotential bonding of 2 or more seperate earth systems is not practical or desirable. The Equipotential Earth Clamp will keep the individual earths isolated until a potential difference occurs across the clamp which exceeds the clamping voltage causing the clamp to close until the potential difference drops below the clamping voltage causing the clamp to open again returning the isolation status of the various earth systems.


Clamps are available is a number of clamping voltage sizes from 90V to 120V and conductor sizes from 16mm to 70mm. Other sizes are available on request.
