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 vendor's batteries, however, are designed for mounting on
stands that require special floor plan arrangements.

Cable and Load
Breaker Sizing
In this paragraph, 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, the 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
paragraph of the product manual. This paragraph derives the
basic 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.
Wire type RHW or RHH should be used for dc power wiring.
This type of wire is commonly available in American Wire
Gauge (AWG) Stranded (e.g., KS-5482) and in a finer stranded
welding type (e.g., KS-20921). 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.
Flexible power wire (e.g., KS-20921) should be used for sizes 1/
0 and larger in applications requiring tight bends, such as small
battery plants in confined locations.
The wire sizes that may be readily terminated at the dc
distribution subsystem are listed in Table 3-D. The distribution
allows direct termination of 4/0 wire. H taps should be used for
