Installing the Breaker in the Breaker Panel CAUTION: For safety purposes, a breaker must be switched to the OFF position when inserted and removed. To install a breaker into the breaker panel, follow these steps: 1. Ensure the breaker is in the OFF position before inserting it into the breaker panel. 2. Install the breaker in the correct orientation, with the breaker handle to the right and the OFF position toward the bottom. 3. Install the two breaker screws.
e. Install and lightly tighten the two M5 screws into the mounting bracket. You will properly torque these screws at a later point. NOTE: The mounting bracket needs to be torqued tight at a certain angle to hold its retainer bracket flush with the CMA. That is why you first install the retainer bracket with lightly tightened screws, position it in place over the CMA, and then tightly torque all the screws in place. 3.
IMPORTANT: Each retainer bracket needs to match the sag of each CMA and remain flush with its CMA in order to properly hold it in place during earthquakes. Otherwise the CMA can slip out from under the retainer and swing freely in the rear of the cabinet, damaging itself and other components in the rear of the cabinet. NOTE: Due to the sag of the CMA from the cable weight, there might be a gap between the CMA and the retainer bracket. To close the gap, press the retainer bracket down onto the CMA. 4. 5. 6.
