Receiving, Handling, and Storing the MCC
See requirements for Moisture Contamination Avoidance and Mitigation for additional information on receiving and inspecting electrical equipment.
Most MCCs are shipped in one-, two-, or three-section shipping blocks with the MCC sections laying on their side on a pallet. At the customer’s request, MCCs can be shipped in a standing position. Some heavier MCC sections are only shipped in a standing position.
Receiving the MCC
Inspect the MCC for damage as soon as it is received. Delivery of the equipment to a carrier at any of the Schneider Electric plants or other shipping point constitutes delivery to the purchaser. Title and all risk of loss or damage in transit shall pass to the purchaser at that time. Refer to the Schneider Electric Conditions of Sale for more details. All claims for loss and damage must be made by the purchaser to the carrier.
If the packaging material is removed, replace it for protection until the MCC is installed.

Moving the MCC
To minimize the risk of injury and equipment damage while moving the MCC, follow these guidelines:
-
Use caution when moving heavy equipment.
-
Verify that the moving equipment is rated to handle the weight.
-
Fork trucks, when available, provide a convenient method of moving MCCs.
-
Use caution when removing an MCC from a shipping pallet. Keep the MCC balanced, and use safety straps and/or taglines as required.
Each shipping block has lifting angles for handling the MCC with overhead cranes. Take the following precautions when using a crane:
-
Handle MCCs in the upright position only.
-
Select rigging lengths to compensate for any unequal weight distribution.
-
Do not exceed the 45° maximum angle between the vertical and lifting cables (see Proper Use of Sling to Lift MCCs).
-
Use only slings with safety hooks or shackles. Do not pass ropes or cables through the holes in the lifting angle(s).
The lifting angle(s) on standard Model 6 MCCs may be removed and discarded. On arc rated MCCs, MCC sections with ArcBlok main breakers, or MCCs with ventilated top plates, the lifting angle(s) must be removed. To prevent entrance of foreign materials, replace all hardware that secured the lifting angle.
Plug-In Units
Some MCC units can weigh up to 200 pounds and require two or more persons or special handling equipment. Lift only by supporting bottom and/or side panels of the unit. Refer to instruction bulletin 80459-641-01, Model 6 Motor Control Centers, for details on unit installation and removal and additional lifting information.
Storing the MCC
| NOTICE |
|---|
|
HAZARD OF MOISTURE INGRESS AND CORROSION
Never store MCCs outdoors. Outdoor storage is inadequate,
even with the protection of a tarpaulin.
Failure to follow these instructions can result in equipment damage.
|
If the MCC cannot be placed into service upon receipt, store it in a clean, dry, ventilated building free from temperature extremes.
See requirements for Moisture Contamination Avoidance and Mitigation for additional information on storage of electrical equipment.
