Step 6

This step describes how to first attach the drive (short rod) end of a 

cable to its interlock assembly and cable bracket . See 

Figure 11

 .

To attach the drive (short rod) end of a cable to the drive lever pull 

swivel fitting (refer to 

Figure 10

), follow the directions below .

1. 

Remove upper nut, compression spring, and 38,1 mm (1,5 inch) 

tube spacer from end of rod of cable assembly .

2. 

Slide rubber boot toward tip of rod .

3. 

Unthread outer bulkhead nut and slide nut and lock washer 

toward tip .

4. 

Insert threaded end of rod into swivel fitting .

5. 

Slide smaller diameter portion of bulkhead fitting into cable 

bracket slot, keeping one of the two lock washers with each 

bulkhead nut .

6. 

Raise the cable assembly until threaded portion of bulkhead 

fitting enters slotted hole in cable bracket (threads show  

above bracket) .

7. 

Bring bulkhead washer and nut down to threads and  

hand tighten .

8. 

Adjust two bulkhead nuts to approximately center the threaded 

section of the bulkhead fitting on the cable mounting bracket . 

9. 

Hand tighten the bulkhead nuts at this time .

10. 

Slide rubber boot back into place over end of bulkhead fitting .

11. 

Replace 38,1 mm (1,5 inch) tube spacer, compression spring, 

and upper nut on end of rod .

12. 

Lower nuts should be against the stop at the end of thread  

and upper nut tightened against tube spacer .

13. 

Hold lower nuts and torque upper nut to 3,3–4,5 N·m  

(30–40 in-lb) . 

To attach the drive (short rod) end of a cable to the drive lever  

push swivel fitting (refer to 

Figure 10

), follow the directions below 

(see 

Figure 11

) .

1. 

Remove upper nut from end of rod of cable assembly .

2. 

Slide rubber boot toward tip of rod .

3. 

Unthread outer bulkhead nut and slide nut and lock washer 

toward tip .

4. 

Insert threaded end of rod with 38,1 mm (1,5 inch) tube spacer 

into swivel fitting, ensuring that the compression spring remains 

between the lower nuts and the swivel .

5. 

Slide smaller diameter portion of bulkhead fitting into cable 

bracket slot, keeping one of the two lock washers with each 

bulkhead nut .

6. 

Raise the cable assembly until threaded portion of bulkhead 

fitting enters slotted hole in cable bracket (threads show  

above bracket) .

7. 

Bring bulkhead washer and nut down to threads and  

hand tighten .

8. 

Adjust two bulkhead nuts to approximately center the threaded 

section of the bulkhead fitting on the cable mounting bracket . 

9. 

Hand tighten the bulkhead nuts at this time .

10. 

Slide rubber boot back into place over end of bulkhead fitting .

11. 

Lower nuts should be against the stop at the end of thread  

and upper nut tightened against tube spacer .

12. 

Hold lower nuts and torque upper nut to 3,3–4,5 N·m  

(30–40 in-lb) .

Step 7

This step describes how to attach the driven (long rod) end of a 

cable attached to an interlock assembly on another breaker to the 

cable bracket and interlock assembly on this Type NF frame breaker . 

Refer to 

Figure 9

 and 

Figure 10

 for cable routing and correct swivel 

fittings to which the cables are connected . 
The driven (long rod) end of the cable is attached to the 

corresponding push or pull swivel fitting on the driven lever on this 

cable interlock assembly similarly to 

Step 6

 except the driven end 

does not utilize a compression spring between the swivel and nut . 

For the push cable, remove and discard the 22,2 mm (0,875 inch) 

cable tube spacer

 (M)

 on the rod end of the cable assembly 

(K)

 and 

replace it with the 30,5 mm (1,2 inch) cable tube spacer

 (J)

 . For the 

pull cable, retain the 22,2 mm (0,875 inch) cable tube spacer 

(M)

 on 

the rod end of the cable assembly 

(K)

 . Install as shown in 

Figure 16

 .
