FLA
= Full Load Amps of Datawave Magnetic Synthesizer
OPD
= Overcurrent Protection Device inside Datawave Magnetic Synthesizer
Wire Sizes based on NEC 1996 Table 310-16, using 75°C copper conductor.
*Parallel Feeders per NEC 300-20 and 310-4.
NOTES:
1.
Main input power feeder
should be dedicated feeder direct from service entrance if possible. Ground conductors recommended
to be insulated conductors run with power conductors for increased system performance. Ground conductor minimum size per
NEC Table 250-95. Input power feeder conduit may be used as the safety ground conductor. When conduit is used, adequate
electrical continuity must be maintained at conduit connections to enclosures and throughout conduit run.
2.
Input feeder wire size
listed in
Table 2
is the minimum feeder size recommended. Larger wire size may be required because of
voltage drop or supply overcurrent protection device.
3.
Output OPD's
listed in
Table 2
are the standard sizes for Model CA only. See the unit's specification sheet.
4.
Output feeder wire size
listed in
Table 2
is the minimum feeder size recommended. Larger wire size may be required because of
voltage drop or excessive neutral current (see NEC Table 310-16 notes 8 and 10). For best performance, Synthesizer should be
located as close to the load as practical.
