Installation Procedure

These instructions outline the recommended installation procedure.

1. Circuit Breaker Preparation

Ensure the circuit breaker is in the OFF/"O" position before installing the plug-in-tulip adapter kit. Turn off and lock out all power supplying this device before installing. Verify that NO voltage is present before proceeding.

Action: REMOVE PRESSURE WIRE CONNECTORS FROM BREAKER IF PRESENT.

2. Attach Tulip Clip Assemblies and Brackets

Place tulip clip assembly (5) into the recess provided on the back of the breaker base molding.

Secure in place using 1/2" belleville washers (6) and 1/4"-20 x 1 hex head bolts (7) (furnished). Recommended tightening torque for these bolts is 60-72 in-lbs [6.78-8.13 N/m] to ensure a good electrical connection. Repeat this procedure for the remaining tulip clip assemblies.

For Current Limiting Circuit Breakers (Load end only): Place tulip clip assembly (5) on the back of the breaker terminal. Attach and shield bracket (13) (from end shield assembly, catalog numbers CLTCJL2 or CLTCJL3) to the front of the breaker. Secure in place with 1/4" belleville washers (6) and 1/4-20 x 1 hex head bolts (7) (furnished). Tighten bolts to 60-72 in-lbs [6.78-8.13 N/m] to ensure a good electrical connection.

3. Secure End Shields and Brackets

Attach end shield (14) to end shield bracket (13) using the four molded pan head screws (15). Tighten screws to a maximum of 5 in-lbs [.56 N/m].

Slide one-piece end shields (8) into the slots provided in the breaker case at the line and load ends of the breaker. For Current Limiting Circuit Breakers, attach one-piece end shields to the load end only.

4. Attach Terminal Shields

Attach terminal shields to the line and load sides of the circuit breaker.

5. Apply Accessory Label

Add accessory label (9) to the top of the breaker as indicated in figures.
