- Groundbed
-
A groundbed is an array of electrodes, known as ground rods, installed in the ground to provide a low resistance electrical path to ground or earth. A groundbed is a component in an earthing system.

Grounding systems
For building electrical grounding systems, an array of ground rods and copper bonding cable would serve as the groundbed. Ground rods can be made from steel with a copper clad surface (typically 2 metre long and 20 mm diameter. These are driven vertically into the ground and bonded together with bare copper wire.
Cathodic protection
In cathodic protection, the anode groundbed is the arrangement of anodes in the ground or water and provides the path for protective current to leave the anodes and enter to electrolyte.
Groundbed materials
Marconite [1] is a material used to make electrically conductive concrete for groundbeds.
