In underground distribution systems, an iron casing or box in which the feeders and mains are joined, and where other junctions are made. Synonym–Fishing Box.

The mechanical equivalent of heat, which if stated in foot-pounds per pound-degree F. units, is 772 (772.55). (See Equivalents.)

The heating effect of a current passing through a conductor. It varies with the product of the resistance by the square of the current, or with (C^2)*R.

This term has been applied to several units. (a) The practical C. G. S. unit of electric energy and work–the volt-coulomb. It is equal to 1E7 ergs–0.73734 foot pound.–.00134 horse power seconds. A volt-ampere represents one joule per second. (b) It has also been used as the name of the gram-degree C. thermal unit–the small [...]

A name proposed to be substituted for “joule,” q. v. It has not been adopted.

Belt-joints for electric plants where the belts drive dynamos should be made with special care. The least inequality affects the electro-motive force. Butt joints are, generally speaking, the best, where the ends of the belt are placed in contact and laced. Lap-joints are made by overlapping the belt, and unless the belt is carefully tapered [...]

The method of joining the ends of stranded conductors. The insulating covering is removed, the wires are opened out, and the center wire, heart or core of the cable is cut off short. The two ends are brought together, the opened out wires are interlaced or crotched like the fingers of the two hands, and [...]

A joint in electric conductors, in which the ends of the wires are inserted into and secured in a metallic sleeve or tube, whose internal diameter is just sufficient to admit them.

A joint for stranded conductors used for Galende’s cables. It is made somewhat like a sailor’s long splice. Each one of the strands is wound separately into the place whence the opposite strand is unwound and the ends are cut off so as to abutt. In this way all are smoothly laid in place and [...]

(a) In belting a joint in which the ends are overlapped, and riveted or otherwise secured in place. If made without reducing the thickness of the ends it is a bad joint for electrical work, as it prevents even running of machinery to which it is applied. Hence dynamo belts should be joined by butt [...]
