Centerline MCC Nameplates & Bucket Labels

Summary

This video explains how to read the main label and individual bucket labels on an MCC (Motor Control Center). It walks through the process of accessing and interpreting the name plate for each section, including important details like catalog numbers, serial numbers, and power ratings. It also covers how to open the bucket door and understand the components inside each bucket, such as circuit breakers, contactors, and safety relays. By understanding this information, users can achieve a more successful integration or modification of their MCC.

Takeaways

• 😀 The main label on the MCC contains critical information such as catalog number, serial number, power ratings, and enclosure type.
• 😀 The MCC features both horizontal and vertical power ratings, as well as details on neutral buses.
• 😀 The type of enclosure is indicated, and in this example, it's a Type 1G, which means NEMA 1 with a gasket.
• 😀 The name plate information also includes the configuration details, such as whether it's a single-section or multi-section MCC.
• 😀 Step one is to access the nameplate of each section to gather information for integration or modification purposes.
• 😀 Step two involves opening the door of the unpowered bucket to read the bucket's label information.
• 😀 The bucket label provides specific information about the components inside, such as circuit breakers or overloads.
• 😀 In the example, the bucket contains a 293F feeder bucket, a NEMA 2113B contactor, and an E300 overload.
• 😀 A 2163 WB label indicates that the MCC bucket also includes a PowerFlex 525 drive along with safety relays.
• 😀 By submitting the name plate and bucket label information to Rockwell, you can request drawings and configurations for further modifications.
• 😀 If there are any questions or issues, it's recommended to contact a local ESN account manager or application specialist for assistance.

Q & A

What is the purpose of the video?

The purpose of the video is to show how to read the main label and individual bucket labels on the MCC (Motor Control Center). It highlights the information required to modify or replace components in the MCC.

What information can be found on the main label of each section?

The main label of each section displays the catalog number, serial number, horizontal and vertical power ratings, amperage, neutral bus configuration (horizontal or vertical), and the type of enclosure.

What does 'Type 1 G' indicate on the enclosure label?

'Type 1 G' refers to a NEMA (National Electrical Manufacturers Association) type 1 enclosure with a gasket.

How can the catalog number and serial number on the main label be used?

What is the first step to access the nameplate of each MCC section?

The first step is to locate and access the nameplate on each section, which contains crucial information like the catalog number and power ratings.

What does the bucket label provide information about?

The bucket label provides information about the components inside the bucket, such as the type of bucket (e.g., feeder bucket), and the specific components like circuit breakers, contactors, overloads, and variable frequency drives.

What does the catalog number '293f' on a bucket label indicate?

'293f' indicates that the bucket is a feeder bucket containing a circuit breaker.

What component does the catalog number '2113b' represent in the MCC?

'2113b' represents a NEMA contactor included in the MCC bucket.

What is the role of the E300 overload in the MCC bucket?

The E300 overload provides overload protection for the motor or circuit connected to the MCC.

How does the information on the nameplate and bucket label help in MCC integration?

The information on the nameplate and bucket label helps ensure a more successful integration or modification of the MCC, as it provides essential details about the components and configuration of the system.
