Abstract
An earthing system for domestic and commercial buildings comprises a lug formed from material compatible with reinforcing used in the building foundation, a flexible conductor and a fixing member. The lug and/or the fixing member are of different material than the conductor and are preferably welded to the conductor using an exothermic welding process.
Claims5
An electrical earthing system which, in use, is fixed to electrically conducting parts of the reinforcing of a building structure, said system comprising:
- (i) a lug formed from the same or substantially the same material as the electrically conducting parts of said reinforcing;
- (ii) a flexible conductor welded at one end thereof to said lug;
- and
- (iii) a fixing member formed of a material of higher electrical conductivity than said lug welded to the other end of said flexible conductor, said fixing member having a substantially planar surface portion, a tapped aperture set into said fixing member through said substantially planar surface portion to facilitate attachment of a further conductor thereto, and at least one aperture passing entirely therethrough and through said planar surface portion, whereby said planar surface portion may be attached to the planar surface of a member used in constructing the building.
