*We recommend that you size fuses such that they do 
not run at more than 70% of their rating. Thus a 70A fuse 
should not be run at more than 49 A. 
 
**The sum of the fuse ratings must not exceed the 
panels rating. 

 
Compatible lugs for Input and Output Blocks

 

(2 hole compression lugs for 1/4” studs on 5/8” centers (torque 3ft-lbs)).

We suggest you heat shrink the barrels of the compression lugs for added safety. 
 
 
 

NOTE:

 If fuse size is not specified in the 

equipment manual, fuses should be selected 
such that they do not run at more than 70% 
of their rating.  When installing fuses, the 
sum of the fuses installed in the panel should 
not exceed the panel’s rating (500 Amps) or 
input fuse rating.
