AMPACITYThe current in amperes that a conductor
can carry continuously under the conditions of use
without exceeding its temperature rating.
AMPEREThe basic unit of electrical current

BILL OF MATERIALAlist of standard parts or raw
materials needed to fabricate an item.
BLOCK DIAGRAMA diagram in which the major
components of a piece of equipment or a system are
represented by squares, rectangles, or other
geometric figures, and the normal order of
progression of a signal or current flow is
represented by lines.
BLUEPRINTSCopies of electrical or other types of
technical drawings. Although blueprints used to be
blue, modern reproduction techniques now permit
printing of black on white as well as colors.
BORDER LINESDark lines defining the inside
edge of the margin on a drawing.
BREAK LINESLines to reduce graphic size of an
object generally to conserve paper space. Two
types: long, thin, ruled lined with freehand zigzag;
short, thick, wavy freehand line.
