It is common knowledge and a very important part of the industry standards that equipment and systems must be properly bonded and grounded to ensure worker and civilian safety from electric shock. There are countless avenues that engineers and installers can utilize to meet grounding and bonding requirements, but the resilience and quality of these methods are not always equal.

Extensive testing has been conducted to evaluate bonding methods and aid in material and product selection to ensure the longevity and continued safety of an installation. This paper and presentation provide testing results of technologies intended to pierce through nonconductive coatings, such as powder coat, and include product reaction to electrical, mechanical and environmental stress. Star washers are compared to WEEB (Washer, Electrical Equipment Bond) washers across this array of resilience test sequences and it is shown that WEEB washers have better performance in almost all aspects tested. Conclusions can be drawn that support the use of piercing technologies in bonding applications that promote the longevity of an installation and safety of the respective system.

Key Points:

  • Bonding technologies are used to increase system safety
  • Nonconductive coatings can be pierced by products intended to create a conductive bonding connection
  • Star washers and WEEB washers were tested based on electrical, mechanical and environmental properties
  • Results support the use of piercing technologies and WEEB washers were show to have superior performance when compared to star washers
