SOURCE: Electrical cable size requirement

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.

SOURCE: Can some one tell me what oil and air filter to

Kohler Model 12RES generator manual calls for use of synthetic oil (Mobil 1 or equivalent) as follows: If temperature is normally above 0 degrees F, use 10W30. If temp. is normally below 32 degrees F, use 5W20 or 5W30. NAPA Auto Parts recommends their #1056 oil filter for the 12RES.

SOURCE: Kohler automatic transfer switch RDT CFNA 0100B. I can set it to exercise and it will do so for several weeks then it forgets. No fault shown.

Product manual does not have troubleshoot section.
The operation might be normal, and within expected parameters, or it might have a glitch.

Kohler 30RYG generator with G220 transfer switch... weekly exerciser stopped running and won't run manually?

Are there any faults listed on the control display? If display is dark then likely a battery issue. Check battery voltage with a Digital Multi Meter (DMM). It should be at least 12.5VDC.

Kohler 20resal 100amp transfer switch RXT will not auto start?

Disconnect generator remote start wires in the ATS. Put an ohm meter across the remote start terminals in the ATS and kill utility power, you should here a click in the ATS and the ohm meter should indicate close to zero ohms. If it does then your ATS is fine and the problem is gen control board or wiring between the two. If it does not show that value, then the start relay in the ATS is suspect.

How do i stop the unit from testing every week?

The automatic test cycle is done for reasons besides just checking to see if it works, it is done to keep the engine in working order. Without running it regularly, it won't be able to run when you need it. If you really don't want the generator as a backup at all, you should sell it. On the other hand, maybe it's just noisy and runs at an inconvenient time. The electrician that installed it probably left a sticker for a number to call on the generator unit itself (or the transfer switch.) for service or questions. They should be happy to answer your questions about changing the schedule of the test cycle - and if they any sense at all for customer loyalty, they will probably do it for free.

My Kohler 17RES has stopped doing it's scheduled weekly exercise. How can I get it exercising again?

On your Automatic Transfer Switch ( the little gray box you see on the right in the picture above) you have two blue buttons. One is a Manual test switch. The other has a clock on it and this is your exercise set button. Hold it down for a FULL 3 seconds if you want it to excercise without a load (not powering your home) Hold it down for a FULL 6 seconds if you want it to exercise with a load every week. Your generator will start and run for 20 minutes, and then shut down. Now every week your generator will exercise at the time and day that you pushed the set button.
