♦  When Distribution Bus Modules Providing Battery Disconnect Fuse/Circuit Breaker Positions are 

Provided: 

Nose-Type Circuit Breakers) are Provided:  Lug-terminated input battery leads are connected to 
the individual battery busbars located on the Distribution Bus Module and the respective battery 
return busbar. 

Battery Load Side:  The individual input battery busbars provide 1/4-20 threaded holes for 
installation of customer-provided two-hole lugs that have 5/8 inch centers and 1/4 inch bolt 
clearance holes.  Refer to the illustrations under the 

 for a dimensional 

drawing.  Maximum size of wire to be connected to a single fuseholder/circuit breaker position is 
2 AWG.    For wiring up to 350 kcmil, see 

, or see the following part numbers in 

 for available 

adapter busbars: 

, and 

. 

Battery Return Side:  The battery return busbar provides 3/8-16 and 1/4-20 captive nuts for 
installation of customer-provided two-hole lugs that have 1 or 5/8 inch centers and 3/8 or 1/4 inch 
bolt clearance holes, respectively.  Refer to "

" 

under PHYSICAL SIZE INFORMATION for a dimensional drawing.  Customer must provide lug 
mounting bolts and hardware. 

b)  When Distribution Bus Modules Using GJ/218 Circuit Breakers or TPH Fuses are Provided:  

Lug-terminated input battery leads are connected to the individual battery busbars located on the 
Distribution Bus Module and the respective battery return busbar. 

Battery Load Side:  The individual input battery busbars provide 3/8-16 captive nuts for 
installation of customer-provided two-hole lugs that have 1 inch centers and 3/8 inch bolt 
clearance holes.  Refer to the illustrations under the 

 for a dimensional 

drawing.  Customer must provide lug mounting bolts and hardware. 

Battery Return Side:  The battery return busbar provides 3/8-16 and 1/4-20 captive nuts for 
installation of customer-provided two-hole lugs that have 1 or 5/8 inch centers and 3/8 or 1/4 inch 
bolt clearance holes, respectively.  Refer to "

" 

under PHYSICAL SIZE INFORMATION for a dimensional drawing.  Customer must provide lug
