A completely new type of earth clamp from Eaton MEM Circuit Protection and Control offers significant advantages over traditional metal models, principally by drastically reducing installation time but also through a superior connection and ease of cross-bonding. Contractors who have tried the new EZYBOND™ earth clamp have been impressed and believe that it could also reduce accidents on site.
EZYBOND™ Advanced Earthing Technology enables the installer to satisfy the requirements of BS 7671 (The IEE Wiring Regulations) for earthed equipotential bonding of gas, water and central heating pipes. It is suitable for single pipe bonding or cross-bonding of a number of pipes.
It uses a one-piece Nylon clamp to hold the bonding conductor in direct contact with the pipe. A conventional “SAFETY ELECTRICAL CONNECTION – DO NOT REMOVE” label is provided.
To install EZYBOND™, the contractor cleans the pipe, as he would with a traditional clamp. He then strips at least 40mm of conductor from the cable, threads this through the safety label and then passes the exposed conductor through two holes in the back of the clamp, bending over the free end. The clamp is then hooked round the pipe and the two jaws are engaged, using finger pressure, and locked into position using gland pliers. The two jaws have a double row of serrated teeth that hold it firmly in place. A security lock ensures a tamper-proof connection.
In field trials, contractors have reported dramatic reductions in installation time compared with traditional earth clamps, resulting in substantial cost savings. It was also much easier and quicker to install EZYBOND™ earth clamps in difficult locations – for example under sinks and baths – where access and visibility are restricted.
The reduced risk, because there are no screwdrivers to slip and injure electricians, and the absence of sharp edges, were also highlighted with particular reference to risk assessment documentation.
However the benefits do not stop here: EZYBOND™ offers a direct copper-to-copper electrical connection and a secure, long-lasting mechanical connection.
EZYBOND™ clamps are moulded from heat- and UV-stabilised Nylon 6.6. This engineering polymer offers excellent mechanical properties, chemical resistance, heat resistance, self-extinguishing properties and freedom from corrosion. While the application to earth clamps is new, double-tooth clamps moulded from the same material have a proven track-record in other applications including the domestic appliance and automotive industries.
EZYBOND™ earth clamps are manufactured in the United Kingdom. They have been tested at an ASTA laboratory to the relevant parts of BS 951:1999 Electrical Earthing - Clamps for Earthing and Bonding and passed all the electrical tests and pull tests on the conductor. They have also undergone the resistance to ageing and resistance to humidity tests of BS EN 60669-1 and the resistance to heat and glow-wire tests of BS 1363-1.
EZYBOND™ clamps are available initially for pipe diameters 15 and 22mm. Each is available for two ranges of conductor size – Sizes A-C (2.5-6 mm2) and Size D (10 mm2). These are colour-coded black and grey respectively for ease of identification.
