Receiving, handling and storage

Heavy weight.

Improper lifting or hoisting can result in death, serious injury or property damage.

Obtain the services of a qualified rigger prior to hoisting the circuit breaker to assure adequate safety margins in the hoisting equipment and procedures to avoid damage.

Introduction

This portion of the instruction manual covers the receiving, handling and storage instructions for a type 38-3AH3 vacuum circuit breaker shipped separately from the switchgear. This section of the instruction manual is intended to help the user identify, inspect and protect the circuit breaker prior to its installation.

Receiving procedure

Make a physical inspection of the shipping container before removing or unpacking the circuit breaker.

Check for shipment damage or indications of rough handling by the carrier. Check each item against the manifest to identify any shortages.

Accessories such as the manual charging crank, the racking crank and the split plug jumper are shipped separately.

Shipping damage claims

Important: The manner in which visible shipping damage is identified by consignee prior to signing the delivery receipt can determine the outcome of any damage claim to be filed.

Notification to carrier within 15 days for concealed damage is essential if loss resulting from unsettled claims is to be eliminated or minimized.

1.When the shipment arrives, note whether the equipment is properly protected from the elements. Note the trailer number the equipment arrived on. Note also any blocking of equipment. During unloading, check the actual equipment delivered to verify it agrees with the delivery receipt.

2.Make immediate inspection for visible damage upon arrival and prior to disturbing or removing packaging or wrapping material. This should be done prior to unloading when possible. When total inspection cannot be made on vehicle prior to unloading, close inspection during unloading must be performed and visible damage noted on the delivery receipt. Take pictures if possible.

3.Any visible damage must be noted on the delivery receipt and acknowledged with the driver’s signature. The damage should be detailed as much as possible. It is essential that a notation "possible internal damage, subject to inspection" be included on the delivery receipt. If the driver will not sign the delivery receipt with the damage noted, the shipment should not be signed for by the consignee or their agent.
