The WRICON Earthing System is designed to allow the entire earthing system to be permanently positioned within the structure itself, protecting it from accidental damage, tampering, or unauthorised disconnection. Safe and effective earthing is a critical requirement of every electrical installation, and reinforced concrete foundations provide an ideal method for achieving a reliable and long-lasting earth connection.

The WRICON Earthing System delivers a permanent, dependable, and maintenance free earthing solution. At the centre of the system is the unique earthing terminal plate, which enables a straightforward and professional connection to the building reinforcement or foundation steel by any competent welder. Earthing directly to reinforcing steel is permitted under New Zealand Electrical Wiring Regulations and offers several significant advantages:

  •   Reinforcing steel within concrete foundations forms a robust and permanent earthing electrode
  • The WRICON earth lead is securely cast into concrete, protecting it from accidental damage during excavation works and reducing the risk of theft
  • Exothermically welded connections provide a permanent molecular bond that will not loosen or deteriorate over time like mechanical compression connections
  • The tinned solid copper head stem, bronze terminal plate, and insulated earth lead help minimise galvanic corrosion while maintaining low resistance connections for the life of the installation
  • Provides lower earth resistance than many conventional earthing methods and is less affected by seasonal ground condition changes

Earthing systems - for all installations

THE WRICON Earthing System provides the means to locate the entire system completely within the structure, thus providing a location away from any possibility of accidental damage or unauthorized disconnection.

Safe and effective electrical earthing is the essential requirement of all electrical installations, and the use of reinforced concrete foundations is an excellent method of achieving this aim.

The WRICON Earthing System permits the installation of an indestructible, totally reliable and constant electrical earth. The heart of the WRICON Earthing System is the unique Earthing Terminal Plate which allows earthing to the building frame (foundations or rebar) to be installed easily, simply and very professionally by any person who can weld proficiently. Earthing to the building frame (foundations or rebar) is permitted under the E.W.R. of New Zealand and the use of WRICON Earthing System has obvious advantages:

  1. Reinforcing steel in concrete foundations provides an indestructible earth electrode.
  2. WRICON earth lead is safely cast within the concrete and cannot be severed by other trades digging for services and is also secure from theft.
  3. Exothermically welded connections (unlike compression connections) do not deteriorate. Additionally the tinned solid copper head lug, bronze terminal plate and insulated earth lead incorporated in the WRICON Earthing System prevent galvanic corrosion and high resistance joints, permanently.
  4. Lower resistance to earth than will be obtained by conventional methods and is much less subject to seasonal changes.
