Earth bonding leads are used for earthing and electrical bonding applications, as flexible electrical connectors and for lightning protection. Manufactured from high grade tinned copper braid to standards EN1977 and EN13602 (supersedes BS4109), high flexibility braid for high vibration areas.
In a building with electricity it is normal for safety reasons to connect all metal objects such as pipes together to the mains earth to form an equipotential zone. This is done in the UK because many buildings are supplied with a single phase supply cable where the neutral and earth conductors are combined. Close to the electricity meter this conductor is divided into two, the earth terminal and the wire going to the neutral busbar in the consumer unit. In the event of a break in a neutral connection this earth terminal provided by the supply company will be at a potential (relative to the true earth) which is the same as the live wire (phase wire) coming to the home.
Examples of articles that may be electrically bonded include metallic water piping systems, gas piping, airplanes, ducts for central heating and air conditioning systems, and exposed metal parts of buildings such as hand rails, stairs, ladders, platforms and doors. For example tower doors on Wind Turbines.
Electrical bonds and earth bonds are typically used in the construction, automotive, aerospace and rail industries, but are also essential for grounding in audio, video and computer systems. We also make a range of earth straps from flat braid and these are on the Earth Straps page
Our electrical bonds are available in lengths and cross-sections (current ratings) to suit your individual needs, and with terminations sized to suit your application. Can be supplied with or without insulation. Insulation colours include Green / Yellow, Black, Blue, Brown, Red. Competitive pricing and ex stock / short lead times.
