Entellisys Low Voltage Switchgear

Chapter 2. Receiving, Handling, and Storage

2-1 Receiving

Equipment Packages

Every package leaving the factory is plainly marked with the

shop order number, requisition number, and customer's order

number. If the equipment has been split for shipment, the

section numbers of the equipment enclosed in each shipping

package are identified.

NOTE:

To avoid the loss of any parts when unpacking,

the contents of each container should be carefully checked

against the packing list before discarding the packing

material.

NOTE:

Le contenu de chaque conteneur devrait être

soigneusement vérifié avec la liste d’emballage avant de

décharger le matériel empaqueté, ceci dans le but d’éviter

la perte de pièces lors du déballage.

The contents of each shipping package are listed on the

Master Packing List. In addition, this list includes the

number of the shipping crate in which miscellaneous parts

needed to install and operate the equipment (such as

hardware, contact lubricant, touch-up paint, breaker closing

devices, etc.) are located. Normally, such devices are packed

in a cardboard carton and the carton secured in an empty

switchgear compartment. See Fig. 2-1. If such items are

packed in a switchgear section instead of a separate crate,

the list will indicate the appropriate section number in which

they are stored. Large items (such as hoist dollies and hoist

carriages used with indoor equipment) will always be shipped

in separate crates or cartons. See Fig. 2-2.

Inspecting for Damage

All equipment leaving the factory is carefully inspected and

packed by personnel experienced in the proper handling and

packing of electrical equipment. Upon receipt of any

equipment, immediately perform a visual inspection to

ascertain if any damage has been sustained in shipping or if

there are any loose parts.

Circuit breakers may be shipped separately in individual

containers with the breaker in the open position. Circuit

breakers should be unpacked and visually inspected for

damage or loose parts as soon as possible after they have

been received.

Be sure to inspect all devices mounted or packed inside

compartments of each section to see if any have been

dislodged or damaged.

Filing a Claim

If any damage is evident, or indication of rough handling is

visible, file a claim for damage at once with the

transportation company and notify the nearest General

Electric Company Sales Office immediately. Information on

damaged parts, part number, case number, requisition

number, etc., should accompany the claim.
