Grounding and bonding are an integral part of any modern electrical protection system design. An effective, low-impedance ground system is a key element of this system. It is crucial to help provide personal safety, as well as reliable protection for vital equipment and to minimize interruptions of service and costly downtime. With over a century of experience in the design and manufacture of bonding and grounding products, ERICO, a single source provider, offers what we believe is the best range of long lasting and cost-effective grounding products available.Soil conditions and seasonal patterns vary from site to site, the methods of grounding need to be considered on an individual basis.

The need to ground! There are important reasons why a grounding system should be installed.

  1. The most important reason is to help protect people!!
  2. To help provide protection of structures and equipment from unintentional contact with live conductors.
  3. To help support maximum safety from electrical system faults and lightning.

It is a fundamental fact that electricity ALWAYS flows to the point of lowest potential. The task is to help ensure that electricity, including faults, lightning and electronic noise, flows to this point with maximum safety to people while maintaining the reliability of equipment. Therefore we must help ensure the safe, controlled flow of electricity with minimum voltage drop to earth in all cases.

Grounding Codes and Standards

Grounding needs vary according to function. The grounding requirements of a power system will vary from those of electrical equipment, lightning protection or for the proper function of electronic equipment.Proper installation of appropriate grounding systems requires knowledge of the needs and layout of the facility. Soil characteristics, grounding conductor materials grounding connections and terminations, are significant factors determining the design of a grounding system. Applicable standards and codes must be applied.

While many codes and standards contain minimum grounding and bonding requirements, the design and installation of electrical grounding systems is one of the most important aspects of any electrical distribution system. However, codes and standards are often misunderstood and grounding systems subsequently installed improperly.

ERICO offers a variety of products, such as ground bars, signal reference grids, ground plates and potential equalization clamps, which are designed to create an equipotential plane and help protect personnel and valuable equipment.ERICO CADWELD copper-bonded or stainless steel earth rods and GEM facilitate the transfer of surges and fault currents into the earth, and provide a very long service life due to superior construction and quality.
