2. Bonding jumper - Wikipedia

   en.wikipedia.org/wiki/Bonding_jumper

   This is done for electrical safety grounding, static electricity protection, and may also be useful for control of electromagnetic interference. For example, a control panel door may have a bonding jumper across the hinges so that the metal door is effectively connected to ground, since the hinges may not provide a reliable contact.

3. Ground (electricity) - Wikipedia

   en.wikipedia.org/wiki/Ground_(electricity)

   To reduce this loss these antennas often use a conductive copper ground screen under the antenna connected to the buried ground wires, either lying on the ground or elevated a few feet, to shield the ground from the electric field. In a few cases where rocky or sandy soil has too high a resistance for a buried ground, a counterpoise is used. [11]

4. Counterpoise (ground system) - Wikipedia

   en.wikipedia.org/wiki/Counterpoise_(ground_system)

   It consists of a network of radial copper wires suspended above the ground, connected to the transmitter feedline ground. It is suspended about 8 feet above ground, so technicians can get access to the helix house at the foot of the tower. Antenna used in Lodge-Muirhead wireless system around 1900, the first counterpoise.

5. Groundbed - Wikipedia

   en.wikipedia.org/wiki/Groundbed

   The electrodes for electrical grounding are often called ground rods and are often made from steel with a copper clad surface – typically 1 to 2 m long and 20 millimetres (0.79 in) in diameter. These are driven vertically into the ground and bonded together with bare copper wire. [1]

6. Antistatic device - Wikipedia

   en.wikipedia.org/wiki/Antistatic_device

   An antistatic wrist strap, ESD wrist strap, or ground bracelet is an antistatic device used to safely ground a person working on very sensitive electronic equipment, to prevent the buildup of static electricity on their body, which can result in ESD.

7. Copper-clad steel - Wikipedia

   en.wikipedia.org/wiki/Copper-clad_steel

   Copper-clad steel (CCS), also known as copper-covered steel or the trademarked name Copperweld is a bi-metallic product, mainly used in the wire industry that combines the high mechanical strength of steel with the conductivity and corrosion resistance of copper. It is mainly used for grounding purposes, line tracing to locate underground ...
