If the power rating listed on the nameplate of the installed UPS is not found in the following tables, wire the
UPS using the fully rated specifications. Otherwise, calculate the required wire, conduit, and breaker sizes
using the following guidelines in addition to those already listed in paragraph 3.2.3:
l
Select wire size according to the UPS nameplate.
l
Do not use wire larger than the largest size listed in Table 3-4.
l
Use terminal recommendations from Table 3-4.
l
Size and number of conduits must not exceed those listed in Table 3-10.
l
Select overcurrent protection input, battery, and output breakers according to the UPS nameplate rated for
either 80% or 100%.
l
Follow all applicable NEC and local codes.
For UPS external wiring requirements, including the minimum AWG size of external wiring, see Table 3-7 for
r
ommended
installations using a common battery system. Wire sizes listed are for copper wiring only.

Battery Conductor Sizing : Eaton strongly recommends using the specified DC conductor size and quantity shown above for optimum system
performance and battery run time.
Battery Cable Routing Requirements
Conduit applications:
* Each conduit must have a Positive, Negative, and Ground conductor.
* There must be an equal number of positive and negative conductors in a single conduit. Only one ground conductor is required in each conduit.
Raceway applications:
* Positive and negative battery cables must be run side by side in the raceway in an alternating pattern (+ - + - + - + -).
* There must be a ground cable running in the raceway with the battery cables.
