For lug mounting hole size and spacing dimensions, refer to the illustration provided in this section.
Restrictions
All lugs for customer connections must be ordered separately.
Customer needs to supply lug mounting hardware
.
Maximum size of wire to be connected to a single lug position is 750 kcmil (2 per lug position).
Maximum lug width, 2.000 inches.

Wire 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 wire 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.
