The AC input branch circuit protective device should be of the time-delay
or high inrush type.

Wire sizes based on recommendations of the American National Standards
Institute (ANSI) approved National Fire Protection Association's (NFPA)
National Electrical Code (NEC). Table 310-16 for copper wire at 75°C and
90°C conductor temperature; operating in an ambient of 40
°
C, was used.
For other operating ambient temperatures, refer to the National Electrical
Code. For operation in countries where the NEC is not recognized, follow
applicable codes.
3 Equipment grounding conductors must be provided with the AC input
conductors supplied to the Bay. Frame ground terminals must be
connected to earth ground, not power system neutral. Equipment
grounding conductor size based on recommendations of the NEC Table
250-122 for copper wire. When aluminum or copper clad aluminum
grounding conductor is used, refer to Table 250-122 for increased
conductor size. For operation in countries where the NEC is not
recognized, follow applicable codes.
