Other vendors' batteries must be engineered per the
manufacturer's instructions. Shelf-mounted batteries, offered by
some suppliers, may be integrated into a frame line-up with the
ECS battery plant. Most other vendors' batteries, however, are
designed for mounting on stands that require special floor plan
arrangements.

Cable and load
breaker sizing
In this section, power cabling for the dc distribution and battery
subsystems is covered, including the following subtopics.
•
maximum and minimum wire gauges
•
wire type
•
crimp lugs
•
circuit breaker selection
To determine actual wire sizes, equipment locations, cable rack
and routing systems at the site must be known. Since the battery
plant shares the cabling system with other building systems,
cabling engineering is not completely defined by this section of
the product manual. In this section, the basics are derived for the
dc power cabling which will be required as part of a complete
cable engineering process. Lucent Technologies offers cabling
engineering services that are separate from battery plant
engineering. Contact your Lucent Technologies Account
Executive for more information on available services.
Use wire type RHW or RHH for dc power wiring. This type of
wire is commonly available in American Wire Gauge (AWG)
Stranded (e.g. KS-24194 L1) and in a finer stranded “welding”
type (e.g. KS-24194 L2). Flexible or Welding Wire is slightly
larger than AWG stranded wire of the same gauge, which may
affect the selection of crimp lugs. For example, different crimp
lugs are required for AWG and Weld wire of the same gauge, for
1/0 gauge and larger. Use flexible power wire (e.g. KS-24194
L2) for sizes 1/0 and larger in applications requiring tight bends,
such as small battery plants in confined locations.
The terminal lugs that may readily be attached at the dc
distribution subsystem are listed in Tables 3-D through 3-G.
