and 250A triple pole. Maximum size fuse is 100A. The distribution row is

rated for a maximum of 250A.

For ambient temperatures between +40°C (+104°F) and +65°C (+149°F),

overcurrent devices rated 60A or greater MUST HAVE an empty

Note: Circuit breakers and/or fuses may have been factory installed for you. If so, verify

their positions and sizes.

Procedure

1) Open the shelf’s front door.

2) Circuit Breakers and Fuses: Ensure that a circuit breaker is in the OFF

position. Orient the distribution device as shown in Figure 2-5. Insert the

terminals on the rear of the distribution device into their corresponding sockets

on the distribution row. Ensure the alarm contact on the back of the distribution

device makes contact with the alarm terminal on the mounting circuit card. Push

distribution device in firmly until fully seated in the distribution row.

3) Fuses: When all fuseholders are installed, install an appropriately sized

TPS/TLS fuse in each. To do this, remove the fuse carrier from the mounted

fuseholder body by pulling it straight out. Slide the fuse in place between the

contacts of the fuse carrier. When done, push the fuse carrier back into the

fuseholder body. Note that a polarizing key on the bottom of the carrier prevents

the carrier from being inserted upside down. Verify that an 18/100 ampere alarm

fuse is present in each fuseholder and that a plastic safety cover is installed on

this fuse.

4) Record all circuit breaker and/or fuse sizes on the label provided.

5) Close the shelf's front door.
