Branch.
A conductor branching from a main line. Sometimes the term is restricted
to a principal conductor, from which current is distributed.
Branch Block.
In electric wiring of buildings, a block of porcelain or other material
with grooves, holes and screws for the connection of branch wires to a
main wire. Its functions are not only to afford a basis for connecting
the wires, but also to contain safety fuses. As when a branch wire is
taken off, fuses have to be put in its line, the branch block carries
these also. One end of each fuse connects with a main wire, the other
end connects with one of the wires of the branch leader or wire.
Porcelain is a favorite material for them, as the fusing or "blowing
out" of the safety fuses cannot set it on fire.
Branch Conductor.
A parallel or shunt conductor.
Brazing, Electric.
Brazing in which the spelter is melted by means of electricity; either
current incandescence or the voltaic arc may be used. It is identical in
general with electric welding. (See Welding, Electric.)
Branding, Electric.
A system of branding in which the heat of electrically ignited or
incandescent conductors is used to produce or burn in the marks upon the
surface. For the alternating current a small transformer is connected to
or forms part of the tool.
