Is there a cheaper way to do this?

We have a 12KW generator. The transfer switch I found is a 'Service Rated 200A auto- transfer switch' $900

They have a cheaper auto switch thats $700 but its not service rated. So I don't think I can use that one.

Any advice on doing this cheap or know a cheap place online I could order this?

The generator is a GE I think. The customer is gonna call and see what he can get. I know some generator transfer switches only work with certain generators.

OK I'll bite.

What are you doing?

Standby generator for a house? A hospital? Your garage?

Is it for the whole structure? A sub panel? Vital loads?

Does switch need to be automatic? Is the genny auto or remote start?

Single phase or three phase?

Coffee, tea, or me? Whoops, sorry wrong question. [Linked Image]

With a generator that small, I'm assuming this is for a house? At 240V, that's about 60A, which isn't a whole lot. Does it need to be automatic? You could find a manual transfer switch for much cheaper, I'm sure.

I agree with Steve.

A 60 amp not service rated automatic or manual transfer switch and a 60 amp panel will be cheaper than the 200 amp service rated ATS alone.

Yes this is for a house.

It does need to be automatic. The generator is auto start.

It came to mind that the switch might need to be generator specific. As in, a Cutler Hammer switch will only work with CH generators... Or GE with GE , etc.

He wants the whole panel powered. He currently has a 12 circuit ATS... but like I said wants the whole panel powered.

Sounds to me if this guys wants his whole panel fired up automaticaly, then he needs the Service Rated, 200a ATS... and we might only be able to get it from the generator manufacturer.. if its generator specific.

Does that sound about right?

Going cheap on a transfer switch is a bad idea.Try kato light they have a big selection.Do they sell them on here?I prefer russellelectric myself.However that would be a huge overkill for a home.I have installed the generac switches in homes.Nothing automatic is going to be cheap price wise anyway.

I don't think Cheap and Automatic Transfer belong in the same sentence.
You can't drive a Cadillac if all you want to pay for is a Yugo.

If Automatic, spend the money and get what you need to do a good, safe job..

If Cheap, Get manual switch, manual start, and warm coat.

I don't think I've ever installed a transfer switch that was made by the generator maker. probably the leader in this field is the company with the unlikely name of "Automatic Switch Company," or ASCO (Not to be confused with the valves of the same name).

Your supply house should be able to put you in touch with a rep. The switch company will help you select the switch, and could very well have someone there to inspect it before you power it up.

Even if you don't need to break a PoCo seal, you really need to get your PoCo 'in the loop.' They will make the appropriate notes, so as to limit the risk to their linemen.

The generator rep ought to also fill you in as to noise, and the regular exercising of the genny. My customers run theirs, weekly. Some transfer the load at this time, others have "load banks" (glorified toasters) that are used. And -trust me on this- noise is a BIG issue. Get the mufler kit!

While transfer switches and solenoid valves aren't exactly interchangeable, both of those product lines are made by the SAME company.

Why does it need to be service rated? are you transfering before, or in main equipment?
