Step 8

This step describes how to adjust the cables to ensure proper 

functionality of the cable interlock setup . Cable adjustments are 

made with the large bulkhead nuts ONLY and with all breakers 

OPEN . Nuts on the rod ends should not be moved . 
Begin by adjusting or verifying that the threaded section of all 

bulkhead fittings are approximately centered on the cable mounting 

brackets, allowing for room to adjust in either direction . Hand tighten 

the nuts at this time .
Perform initial adjustments on the driven (long rod) end of cable 

until the gaps identified in 

Figure 12

 through 

Figure 15

 are as 

specified . 

Figure 12

 through 

Figure 15

 show the position of the 

interlock assembly driven “And” lever based on the state of the 

interconnected breakers .

If there is 

too much clearance

, adjust both bulkhead nuts to retract 

the cable housing (move threaded portion down) .
If there is 

no clearance

, advance the cable housing in the same 

manner (move threaded portion up) .
If 

additional adjustment length

 is needed, the bulkhead nuts on 

the other (drive) end of cable can be used .
When the proper clearance is attained on the driven end, torque 

both cable bulkhead nuts to 11–13 N·m (100–120 in-lb) without 

moving the bulkhead fittings .
After the driven end has been adjusted and the bulkhead nuts have 

been tightened, perform adjustments on the drive (short rod) end 

of the cable . Adjust the bulkhead nuts up (move threaded portion 

down) such that the gap between the drive lever and the interlock 

assembly base shown on 

Figure 10

 is less than 8 mm .

When the gap is less than 8 mm, torque the cable bulkhead nuts on 

both ends to 11–13 N·m (100–120 in-lb) .
