INTRODUCTION
A project has been undertaken to convert No.3 Pump House into two distinct sections. A
plant room to house existing air compressors, dryer / receiver and a switchroom separated
by an internal wall.
This report details the basis of design for the Motor Control Centre (MCC) for the
switchroom. Referring to the overall switchroom basis of design document
(SI451001_RPT), two MCCs are proposed, although it is likely these will be installed one
at a time.
A typical soft start circuit drawing has been produced and is appended to this document
(SI451001_DWG). Fully detailed individual circuit drawings, both soft start and DOL will
be produced for construction.

Basic Requirements
The MCC(s) will be designed and constructed in such a manner that they are modular in
nature and thus provide a consistent interface to the end user regardless of the degree of
complexity for the particular drive. The following basic criteria will be applied.
Construction
Floor mounted, Back to Back, Front entry only, top entry only for
cables
Drive Starting
Direct On-Line Starting for Drives < 15kW
Soft Start for Drives ≥15kW
