Preparing the breakers for installation
Certain breakers require preparation before installation onto their adapter module. Preparation
procedures are described below. The identified parts are included with your circuit breaker kit.
Slide the bracket adapter onto the output side of the T1 single-pole breaker. The bracket adapter is
used to attach the breaker to its adapter module.
The T1 three-pole breaker requires no additional preparation.

The input and output sides of the T3 three-pole breaker require preparation:
On the input side, follow these steps for each of the three pole positions:
1. Place an M8 square nut into a square nut retainer, then insert the retainer into the pole position.
2. Slide an M8 washer onto an M8 bolt, then insert the bolt into the pole position by loosely
attaching it to the M8 square nut that was installed in the previous step.
On the output side, follow these steps for each of the three pole positions:
1. Slide a saddle lug into the pole position. You may need to loosen the bolt in the lug.
2. Insert a saddle lug retainer into the pole position.
