• Chillers may be purchased with either Main Terminal Block, Disconnect or Circuit Breaker. 
• The lug size on the respective component will accept a certain wire size and the number of poles per phase.
• The catalog and IOM might not have the most current data, so the most accurate document which will have the correct information is always listed on the submittal.
• Refer to it to determine which size wire size and the number of wires that should be used/pulled.
• Wire range size per lug information is included in the dimensional drawings exportable from TOPSS. (see attachment below for visual reference)
