Power Only Bay DC Output Cable Sizes and Lugs
Features
♦ Studs (3/8-16 on 1" centers) are provided for installation of customer provided two-hole lugs. These
studs are accessed from the rear of the each Power Only Bay. (Overhead busbars may be furnished.
Refer to the section titled Power/Distribution and Power Only Bays External Busbars under "Accessory
Descriptions" for battery lug selection.)
♦ 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.
Ordering Notes
1) DC output cable size varies depending on power requirements, therefore no specific information is
provided for cable size. Refer to Table 12 for recommended cable sizes and lugs at rated maximum bay
output (2200 amperes). When making connections, observe correct polarity.
2) For other available lugs and hardware, refer to drawings 031110100 through 031110300.

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 310-16 for copper wire rated at 90
°C conductor temperature operating in
ambients of 30
°C and 40°C was used. For other operating ambient temperatures, refer to the
NEC. 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.
