FAQ: How do I ground materials and carts to a conductive tile floor?

Grounding carts - ESD FlooringTo ground materials or carts to ESD flooring, add conductive drag chains or casters.

The photo below shows a conductive vinyl tile installation. This client planned to use wire shelf carts to move electronics assemblies around the floor. Although the floor is grounded and conductive, the cart could not be grounded because its wheels are insulators.

Static cannot discharge through an insulator—even if the insulator is resting on a static-protective floor. The cart in the photo does not have a conductive drag chain or conductive casters. Adding conductive wheels or drag chains to the cart will drain static charges to the floor.

More on insulators

Insulators can never be grounded, because insulators are inherently non-conductive.

Examples of common non-conducting materials are:

  • Rubber sole shoes
  • Child-proof electrical outlet covers
  • Plastic wrapped around an electrical wire, preventing electrical shocks.

Floating conductors

The metal cart, pictured above, with no ground chain or conductive castors is a “floating conductor,” as its insulative wheels are insulating it from ground. Since the rest of the cart is metal and conductive, it will potentially accumulate static and store it—the same way a capacitor stores voltage.

What is a floating conductor?

Any conductive object electrically separated from ground. In the case of the metal cart, the metal is conductive and the floor is considered ground. By the exact same principle, people walking on an ESD floor wearing regular street shoes are also floating conductors.

What does ESD mean?

ESD stands for electrostatic discharge. Minute ESD events, too small for humans to perceive, can damage electronic components.

Is wood antistatic?

No, wood is not antistatic. You can learn which materials are antistatic and which are not by looking at our Triboelectric chart.

What are ESD guidelines?

Because different applications require different specifications for static control, ESD guidelines, or standards, vary across industries.
