3BUS 208 000 R130160 Utility Service Installation
Figure 4-3 Standard Cable Configuration
The main supply to the SP is to be from the same supply as the host system. If there
must be a deviation, then the two supplies must be banded to the same ground (single
point earth reference). The introduction of an extra grounding system such as an
instrument ground is absolutely forbidden.
A neutral to ground bond must exist on the secondary side of the SPDC. This bond
must be in the SPDC and only in the SPDC.
The SPDC is 10 KVA to handle the largest SP system. Your particular installation
will probably not actually consume that much power. The input wiring, fusing, and
disconnect should, however, still be sized for the full 10 KVA.
Allowable input voltages to the SPDC are:
• Rated Input Voltage: 240, 230, 220, 208, or 200 volts ± 10%
• Rated Frequency: 50 or 60 Hz ± 1%
The secondary is always wired as 120/240.
