ATS outside enclosure

[bigbadbobszoomzoom]

When installing a 15kw package system, the transfer switch comes as "indoor use only" which I think is a NEMA 1 rating. I need to place the transfer switch outdoors (NEMA 3) and have not been able to find an enclosure within size reason 30" x 14" x 7". Who or where can I purchase a compatible box from? :confused:

I suspect that is an uncommon size. The boxes I see listed that are 30" high are 24" wide. You should expect to pay big bucks for the box. A 30x24x9 box costs $327 at http://www.mcmaster.com/ , search for "nema enclosure".

However, the specs for the Guardian transfer switches (without the breakers) show them to be in NEMA 3R rated boxes. So you must be referring to the ones with breakers.

Yes, the transfer switch is the one that comes as a package unit with the generator. What are the installers using? I visited a fellow a while back and he built a gawd awfull box using cedar fence pickets. Bet he burns his house down sooner or later. I want my install to be as professional and to code as possible so red cedar is out of the question.

What you are tying to do is a little different than usual. Not that it can't be done. Enclosures are available but as cosmicvoid pointed out expensive. Aestheticlly speaking, if it can be worked out and built, a raintight waterproof enclosure can be built around it. This might require a door etc. Like I say that may not be feasable. In the end that might be just as expensive as a gasketed nema 3 enclosure.
And we are assuming that it is impossible to install indoors. The panel must be right on the other side of the wall in a finished looking area.
Electrical supply houses are usually wholesale only. On line is your best bet. A little more info might help us figure it out better.

The problem with your situation is how the guardian generator and transfer switch communicate. Most generators are slaves to the transfer switch. But in the case of guardian systems, the transfer switch is being controlled by the generator.

I do not know of any other systems on the market that use a dummy transfer switch like the guardian setups. We've installed over 1000 generators here in Michigan, and I've yet to across a house where there wasn't a good way to handle the situation.

if you can post digital photos, I can hopefully assist you in your placement, or help give you a fresh idea on how to go about doing it.
