Final Check List Before Energizing
Introduction
This section provides guidance for the startup of a newly installed
MCC.
We recommend making an itemized list including:
• 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.
• other important data.
The itemized list could be modeled after the MCC layout drawings
supplied with each MCC. This itemized list should be saved 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.
