Categorization of cables by E3 characteristics provides
opportunities to bundle similar cables together, thereby saving cable
installation space requirements in wireways. Categorization allows cables of the
same category to be run in the same bundle or in close proximity with other
cables of the same category.
As a minimum, all cables should be categorized based upon an E3
category. The following procedures may be used to categorize each wire or cable
according to its interference or susceptibility characteristics. Wires and
cables should be marked in such a manner that personnel can visually identify
the E3 category for each wire or cable. Wires and cables should also
be identified, in order of E3
priority, as listed in Table 4-2.
