- Part 5: Grounding and bonding: Generator sources and transfer switches Two professional engineers (Dan Carnovale and Tom Domitrovich) with years of power systems experience will clarify this often misunderstood concept while making reference to NEC.

What you've describe is well and good really for the 3 phase system. In a split phase system you could have a 3 Pole switch, (2 hots 1 neutral), with 1 pole used to switch the neutral. Well, most generators today rated over 5k in have a neutral-ground bond. It'd be nice if Eaton actually sold a transfer switch/panel that switches the neutral with a 3rd pole. As it things stand right now eaton only sells one transfer switch that switches the neutral model CH10GEN5050SN. Be nice if you have a 100amp version with more circuits than the measly 10 that this current iteration has
Tom, thank you for this video. I was having a difficult time convincing a generator representative to keep the derived grounded neutral conductor in the generator isolated from the enclosure. (The generator ATS does not switch the grounded conductor). I forwarded this video and I hope it helps him! Don H
I installed a switch in the middle of the bonding wire on the generator. It's off when running the cabin through a transfer switch and on when power tools are plugged directly into the generator.
did the same so I can use the generator for house OR stand alone. problem is educating others who operate the generator as to why
how the generator neutral return current will flow back through the other separately derived system and the Generator neutral is not grounded ( it is an open circuit)?
Great safety information thanks
Can the ground rod on the service equipment be used to ground the generator since it’s connected to it through the egc?
