I am considering installing a Kohler 12RES-L standby generator. There will be a 100 foot run from the planned location of the generator to the transfer switch. What rating and type of electrical cable would you recommend. I expect to bury it in a conduit.

This is an answer to your question only. The safest thing to do is hire an electrician to do it. There may be factors you don't recgonize that a skilled eye would pick up on.
The proper size wire is #4 copper or #3 Aluminum. THHN is the most common and most versatile type in conduit. a #6 ground wire is ok. Stranded pulls a lot easier than solid and do yourself a favor and buy some wire pulling lubricant just in case.
Make sure to obey all manufacturer's instructions. If you use aluminum make sure to place anti-oxidation compound or Nolox on your lugs in the panel. Please write back with anymore questions.
