2. Where the trade size of the conduit used is smaller than the
trade size for which the conduit knockout is sized, use
appropriate knockout reducing washers.
Use the wire or cable in Table 5-A where available. Otherwise,
use commercial UL listed wire or cable that meets the National
Electric Code (NEC) and local requirements.
•
KS20747 for conduit applications requiring a 28% oxygen
index.
•
KS22641 for conduit applications with a 23% oxygen
index.
•
KS23747 armored cable with an insulated ground
conductor.
Table 5-A shows the recommended customer-supplied fuse size
and type for the branch circuit protection located in the ac
service panel supplying the rectifier input circuits. The fuse
types shown are BUSSMANN
TM
fuses. Equivalent UL listed
fuses or circuit breakers can be used in lieu of the fuses shown.
If circuit breakers are used, they should have trip elements of an
equivalent rating to the recommended fuse.
The “green wire,” ac equipment ground (AC EG), is also known
as frame ground (FR GRD). The connection for this ground is
on the inside back wall of the rectifier.
The rectifier also requires a supplementary parallel ground,
called central office (CO) ground. Two connections for this
ground are labeled on top of the rectifier. Only one connection is
required, whichever is more convenient. (See page 5-12 for
installing the CO ground.)
DC Output Power
The J85503B-2 rectifier requires dc output cables connected to
each of the positive and negative output terminals. Figure 5-3
shows the output terminals. Figure 5-4 shows the opening in the
top of the rectifier for the dc output cables. Table 5-B specifies
possible dc output cable sizes and their connectors.
The 4/0 cables allow for a maximum loop length of 100 feet
while limiting the voltage drop to 2 volts between the rectifier
output terminals and the batteries. The rectifier's regulation
circuit, if connected, compensates for this drop. For a longer
loop length, to reduce heat in cable racks, or to reduce the
voltage drop from the rectifier to the battery, larger wire may be
