14 Alpha Conventions
14.1 Numbering System
Alpha Technologies uses an eight-digit drawing number system, which is broken into three blocks. The first three
digits describe the category of the product; e.g. rectifier or fuse panel. The next three digits indicate the sequence
in which the product number was allocated in a particular category. The last two digits indicate the type of
drawing, for example:
“-06” Outline Drawing
“-08” Customer Connections
“-20” Main Assembly
Alpha uses an eight-digit part numbering system for all components and sub assemblies. Each part is covered by
its own unique number. Due to the quantity, categories will not be listed within this manual.
