Hello, I am a retired water utility electrician. Over the years I had worked with 3 phase gensets and many controls. Water utilities are not under the code restriction. But we had electrical engineers working with us to keep close to the code as possible. I am installing a home 12kw single phase 240v unit for my trailer. An existing 100 amp manual transfer switch mounted on a power board outdoors with the main panel will be used. The transfer switch does not switch the neutral. I have placed the genset in my garage 100 feet away. From there I will be running #6 in conduit to the transfer switch. Now my question is (I have been out of touch with the code) can I run my 3 each #6 in the exisiting garage sub panel supply conduit back to the switch? Or do I have to install a separate conduit just for the genset? The 1 1/2 conduit has exisiting 4 each #6 for the garage sub panel. There is also a question about the bonding. I will be grounding the genset at the garage with a ground rod. But do I have to run another green from that ground back to the main? Or can I use the garage sub panel green? The sub is also grounded to rods.
