Cable sizes are based on recommendations of the American National Standards Institute (ANSI) approved
National Fire Protection Association's (NFPA) National Electrical Code (NEC). Table 310.15 (B) (16) for
copper wire at 90°C conductor temperature. For operation in countries where the NEC is not recognized,
follow applicable codes.

Recommended cable sizes are sufficient to restrict voltage drop to 1.0 volt or less at rated full load output
current of the bay for the loop lengths shown. Loop length is the sum of the lengths of the positive and
negative leads.
