2. Bonding jumper - Wikipedia

   en.wikipedia.org/wiki/Bonding_jumper

   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. Temporary bonding jumpers are used in the handling of flammable liquids and gases, so that static charge on a vehicle or portable tank does not ignite ...

3. Three-prong adaptor - Wikipedia

   en.wikipedia.org/wiki/Three-prong_adaptor

   The ground tab is designed to be attached to the outlet faceplate screw, which is supposed to be connected to the building electrical ground. A cheater plug, AC ground lifter or three-prong/two-prong adapter is an adapter that allows a NEMA 5-15P grounding-type plug (three prongs) to connect to a NEMA 1-15R non-grounding receptacle (two slots).

4. Copper tubing - Wikipedia

   en.wikipedia.org/wiki/Copper_tubing

   A similar bonding jumper wire is used between the inlet and outlet of gas meters, but here the purpose is to avoid having a substantial voltage difference between the building’s grounding electrode(s) and buried natural gas lines appear across the gas meter during the brief interval when a line to ground fault is conducting before the ...

5. Electrical conduit - Wikipedia

   en.wikipedia.org/wiki/Electrical_conduit

   Sometimes the fittings are considered sufficiently conductive to bond (electrically unite) the metal conduit to a metal junction box (thus sharing the box's ground connection); other times, grounding bushings are used which have bonding jumpers from the bushing to a grounding screw on the box.

6. NEMA connector - Wikipedia

   en.wikipedia.org/wiki/NEMA_connector

   The ground pin is round, like those on straight-blade NEMA grounding devices. Referring to the picture, the orientation is the same as the NEMA 5 plug and receptacle, with the neutral blade on the lower right. Adapters are available with the TT-30P plug on one side and a 5-15R or 5-20R receptacle on the other side.

7. Multipoint ground - Wikipedia

   en.wikipedia.org/wiki/Multipoint_ground

   A multipoint ground system is more complicated to install and maintain over the long term, and can be more expensive to install. Star topology systems can be converted to multipoint systems by installing new conductors between old existing ones. However, this should be done with care as it can inadvertently introduce noise onto signal lines during the conversion process. The noise can be ...

8. TIA-607-B - Wikipedia

   en.wikipedia.org/wiki/TIA-607-B

   Among TIA-607-B's list of metallic components in need of bonding are racks, enclosures, ladders, surge protectors, cable trays, routers, switches and patch panels. Following the bonding of telecom infrastructure components, the entire system must be bonded to the building's main ground, which is sometimes also referred to as a grounding ...

9. Ground (electricity) - Wikipedia

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

   Strictly speaking, the terms grounding or earthing are meant to refer to an electrical connection to ground/earth. Bonding is the practice of intentionally electrically connecting metallic items not designed to carry electricity. This brings all the bonded items to the same electrical potential as a protection from electrical shock.
