Standard Low Voltage MCC Pull Box

Turn off all power supplying this equipment before working on or inside the equipment, and follow lockout/tagout procedures. Always use a properly rated voltage sensing device to confirm power is off.
Remove the 3/8-in. (9.525 mm) bolts, washers, and the lifting angle (see Remove the Hardware).

Remove the Hardware
Remove the 10-32 screws that secure the top closing plate to the top of the cabinet (see Remove the Hardware).
Remove the top closing plate from the structure.
Remove the front panel from the pull box. Position the pull box on top of the cabinet as shown in Install the Pull Box.

Install the Pull Box
Install the two 3/8-in. (9.525 mm) bolts and washers that were removed in Step 2. Place them through the pull box lower side channels and into the top of the cabinet. Torque the bolts to 28–33 lb-in (3.164–3.729 N•m).
Re-install the pull box front panel removed in Step 5 and the top closing plate removed in Step 4 (see Install the Pull Box).
