Refer to Tables A through M for wiring requirements. If an output lockable disconnect is
required, it is to be supplied by designated personnel.
14. Table V lists the maximum rating for input circuit breakers. When wiring a single feed

maximum input circuit breaker current ratings from Table V in accordance with the
National Electrical code, ANSI/NFPA 70.
15. When the optional Options Cabinet is used, source protection for the AC input should be
treated as if you were supplying a 20 kVA three phase transformer for the
Powerware 9330 (10 kVA---20 kVA) and a 40 kVA three phase transformer for the
Powerware 9330 (25 kVA---40 kVA), to allow for inrush current.
