Portable Earthing Devices (portable earths) are personal protective devices that are used to protect electrical workers if the high voltage equipment they are working on is re-energised. In the event that a conductor is energised inadvertently, the aim of portable earth is to: + provide a controlled path for the short-circuit current away from an exposed worker to allow short-circuit detection equipment to operate and disconnect supply quickly, and + to minimise the voltage rise and reduce the chance of electric shock occurring. Copper Cables with silicon sheaths to IEC-61230,
Portable Earthing Parts
- Earthing End Clamp suitable for ball type earthing stubs (ball heads of 20 or 25mm)
- Operating pole with operating socket as short as possible (safety clearance can be reduced as all operation are going to be done on ‘dead’ circuit) -fibre glass material preferred
- Earth Leads 150sqmm, aluminium conductor, sheathed with clear PVC at least 3m
- Earthing End Clamp to earthing bar width 50mm
- Pfisterer 360333333 Clamp
- Wooden Earth Rod and Clamp or Independent temporary earth electrode (Earth Stake)
- Portable Earth Lead – 125mm2 - 130mm2
- Input Protect Fault Indicator
