Grittins. I'm wiring a 24kw genny and a 200a ATS at a house that has a 150a MB panel inside that should have had an outside main, but didn't, so I have to separate the neutrals and grounds. Oh, joy! The meter base is already a 200a one, and I'll be using 4/0 SER, so I'm calling it an upgrade so the POCO won't apply any charges for their work.
My question is about the genny feeder. It's only about 12', so I'll use individual copper conductors in PVC and run it outside the foundation instead of through the crawl space. The genny has a 100a breaker, so I plan to use three #3 wires and a #8 EGC. According to my conduit-fill calc, as soon as I add one #14, it bumps the PVC from 1" to 1-1/4".
The genny requires six control wires, so, my question is whether the calculator (http://www.electrician2.com/rveltrain05/rf_calculator.html) is correct, and would I be better off running a 1" and a 1/2" PVC or a single 1-1-4" PVC? I would check using the NEC numbers, but frankly, I'm too sick today to concentrate enough to do the math.
Thank you in advance for any responses.
