B

Bonds:

bond
A piece of metal conductor, either solid or flexible, usually of copper, connecting two points on the same or on different structures, to prevent any appreciate change in the potential of the one point with respect to the other.

continuity bond
A bond designed and installed specifically to ensure the electrical continuity of a structure.

NOTE. This may be permanent or temporary. In the latter case it is used to connect two sections of a structure which would otherwise be disconnected during a modification or repair.

drainage bond
A bond to effect electric drainage.

remedial bond
A bond installed between a primary and a secondary structure in order to eliminate or reduce corrosion interaction.

resistance bond
A bond either incorporating resistors or of adequate resistance in itself to limit the flow of current.

safety bond
A bond connecting the metallic framework or enclosure of electrical apparatus with earth, in order to limit its rise in potential above earth in the event of a fault, and so reduce the risk of electric shock to anyone touching the framework or enclosure.

bond resistance
The ohmic resistance of a bond including the contact resistance at the points of attachment of its extremities.
