Final Checklist Before Energizing
Introduction
This section provides guidance for the startup of a newly installed MCC.
We recommend making an itemized list including the following:
• Serial number
•Number of sections
• Number of units and their corresponding voltage
• Current ratings
•Horsepower ratings
•Types of circuits
• Fuse sizes
• Circuit breaker ratings and trip settings
• Heater elements requirements
• Arc resistant components
•Other important data
The itemized list could be modeled after the MCC layout drawings supplied
with each MCC. Save this itemized list in a file along with other data for the
MCC such as, component manuals, heater element instructions, MCC
manuals, and wiring diagrams. Blank sample forms are provided at the end of
this chapter.
