Spoke to local Kohler rep this morning regarding install of 14RSEA 14k Generator, RDT-CFNC-200ASE Transfer switch and carb heater. Based on his input and my application and after consulting documentation. It looks like Figure 2-10 Connection Diagram, 200 Amp Service Entrance Model Transfer Switch Kohler RDT manual fits my application.
I have a few questions:
1. How many conductors are needed to control the starting of this generator? Looks like 2, 20 gauge, for a 70 foot run between the generator and transfer switch. He mentioned getting Belden 9402 cable, however this cable contains two pairs, so curious what I would use the other two conductors for.
2. Are two independent 120V feeds required for the carb heater and battery charge function? Looks like there may be one breaker in there to supply power from the transfer switch to do one or the other, and an additional breaker would have to be installed supporting both functions.
3. How would the other options such as a crankcase heater, an enclosure heater, etc. be powered.
4. Is any additional signal/control wiring required other than a CAT 5E or CAT6 cable?
I may be increasing the size of the generator in the future, therefore the 14k/200A transfer switch selection. Focused on control wiring for now, will install larger conduit now for upsizing the feeders, as required in the future. Just need the 14k for now as this project is multi-phased and based on a number of factors I chose to do it this way. Will be powering/protecting from freeze (Propane fired hot water heatingsystem) apartment and garage off this generator for the next 3 years before completing main house.
Generator will be located 10 miles from Saranac Lake, NY and will be exposed to temps in the -25F degree range from time to time. I anticipate having to install all heating options beyond the carb heater I have at the moment.
