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.

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.
