1
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 90°C conductor temperature, operating in ambients of 30
°C and 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.
2
The AC input branch circuit protective device should be of the time-delay or high inrush type.
3
Two-hole lug, 1/4” bolt clearance hole, 5/8" centers. Refer to drawing 031110100 for lug crimping
information.
4
One-hole lug, 1/4” bolt clearance hole. Refer to drawing 031110100 for lug crimping information.
5
Equipment grounding conductor size based on recommendations of the NEC Table 250-122 for copper
wire. If 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.
6
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.
