A bonding jumper is a reliable conductor to ensure the required electrical conductivity between metal raceways required to be electrically connected. [ 1 ] Wide metal bonding straps around the joints of a radio antenna mast.
Bonding is also used to minimize electrical arcing between metal surfaces with electrical potential differences. If a failure of electrical insulation occurs, all bonded metal objects in the room will have substantially the same electrical potential, so that an occupant of the room cannot touch two objects with significantly different potentials.
In the less-dangerous instance of a bootleg ground, a short wire jumper is connected between the bonding screw terminal (usually colored green) on a NEMA 5-15R or 5-20R outlet to the neutral (a.k.a. grounded conductor, colored white according to code) or directly to the white neutral wire via a pigtail.

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. [10]
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 ...
Exothermic welding, also known as exothermic bonding, thermite welding (TW), [1] and thermit welding, [1] is a welding process that employs molten metal to permanently join the conductors. The process employs an exothermic reaction of a thermite composition to heat the metal, and requires no external source of heat or current.
Different types and colors of jumpers, with two individual black jumper pins on the left for scale. In electronics and particularly computing, a jumper is a short length of conductor used to close, open or bypass part of an electronic circuit. They are typically used to set up or configure printed circuit boards, such as the motherboards of ...
