Hello Gnatius;
My name is Michael.
Saw your portable generator hookup video, nicely done!

We interlocked the service entrance panel (outside), consulted/hired a licensed electrician to acquire correct parts and perform the install.


Found a sticker that reads:
WARNING: for connection of a nonseparately derived (floating neutral) system only.

Haven't seen this warning discussed in any of the install videos.

Could you explain how/if this would apply to interlock/portable generator installs?

Sincerely;
MB

When a power source is labeled as having a "floating neutral" it means that the ground and neutral are not bonded together; in other words, neutral is not derived from ground.  On a generator that would mean that the neutral wire is not bonded to the generator frame.

So when your transfer switch says it is intended to be used with a "nonseparately derived" power source, it really just means the neutral is not switched, and if you want to be absolutely ultra-code-compliant, you should use it with a generator that has a floating neutral.

In practice, nobody cares about this.  Plug your generator in and enjoy.

I'm actually starting to look at generators for the house.

I'm considering a Generac natural gas powered generator with an ATS, to power my entire property in the event of a major commercial power outage.

natgas generators make me a bit nervous, because you're still depending on a utility, just a different one. The idea is that you want to be able to use an onsite supply of fuel. If you don't want to deal with gasoline, consider diesel or propane.

Automatic transfer switches are nice. They are, of course, also quite expensive.
As part of a thousands-of-$$$ installation with a big generator and professional installation, it's not that big a component though.

I personally don't mind hauling out the portable diesel generator and plugging it in. And the video I made about it has paid for the generator several times over, which is nice. And I sold the house in the video, with the transfer apparatus ... to an electrician! We've been in the new house for over four years and I still haven't wired it for the generator, because the power here goes out so infrequently. But when it does, the extension cords are quite a nuisance.

I don't know why but I think IGnat would like this.
