Notes to Table 15:
1
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 310-16 for wire rated at 90
°
C conductor
temperature operating in ambient temperatures of 40
°
C, 50°C, and 65°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.
2
Recommended wire sizes are sufficient to restrict voltage drop to 1.0 volt or less at listed branch current for the loop lengths
shown. Loop length is the sum of the lengths of the positive and negative leads.
3
Wire Size / Loop Length Combination Calculated using 40°C Ambient Operating Temperature.
4
Wire Size / Loop Length Combination Calculated using 50°C Ambient Operating Temperature.
5
Wire Size / Loop Length Combination Calculated using 65°C Ambient Operating Temperature.

Features
♦
In each Distribution Cabinet, lug-terminated battery conductors are connected to the battery terminals as follows: Each
Distribution Cabinet provides the following connection points for two-hole lug-terminated battery wires:
•
Lists AA, AB, AC, FA, FB, FC and MV: Battery and Battery Return busbars provide 3/8” threaded studs on 1”
centers.
•
All Other 1-Row Distribution Cabinets: Battery disconnect positions provide 1/4“ threaded studs on 5/8” centers.
Return connections can be made to Battery Return busbar, which provides 3/8” threaded studs on 1” centers.
Return connections can also be made to Load Return busbar, which provides 1/4“ threaded studs on 5/8” centers.
•
All Other 2-Row Distribution Cabinets: Battery disconnect positions provide 1/4“ threaded studs on 5/8” centers.
Return connections are made to Load Return busbar, which provides 1/4“ threaded studs on 5/8” centers.
