Connect T6 and T9     Neutral     -    Note: A Delta connection is only available for twelve lead generators.Note: A Delta connection may require certain generators to be derated.Generator line leads (T1 through T12) can be multiple. For example, three generator line leads might be designated as T4. Multiple line leads allow the leads to be flexible. Flexible leads help maintain the current carrying capacity which is required. If generator line leads are similarly marked, these leads should be connected together. These leads should be treated as one conductor. Generator line leads can terminate in the following ways:
end at the terminal strip
directly fastened to the load leads
fastened to another componentFor more information, refer to Testing And Adjusting, "Leads - Connect".Depending on the connections that are made between the load and the generator line leads, single-phase voltages and/or three-phase voltages are possible. For more information, refer to Operation and Maintenance Manual, LEKQ7119, "Engine Data Sheet".
