I recently prucahsed a used Guardian 5244 16kw with 20-30 hrs on it. Like new condition $1000. I did not, however get a transfer switch as the previous owner didnt want to dismantle his sub pannel. I want to use a whole house ATS and found a good deal on a new one on ebay. It is a RE200A3 and my question is, "is this switch compatable with my unit"? My service at my home is 200 amps.

That switch will work with the generator you purchased.

Thanks for the quick reply......are you a dealer? Do you have this model? I am just trying to understand how you know it will work...Thanks

The transfer switch is a standard two wire start. #23 and #194 along with utility sensing n1 and n2.

How/what configuration do you plan on using hooking up the unit?

I am going to use it as a whole house transfer switch I assume. At least I am hoping to....I have a 16kw unit so I assume this can be done no problem? I am having an electrician do the work...

Don't assume.

Whether or not you can use the 16kW unit as a whole-house generator depends very much on what codes your local government has adopted. If they are using the 2008 version of the NEC (National Electrical Code), you will have to do a rather involved calculation of all the loads in the building to determine the minimum size of generator that you need.

My guess is that a 16kW generator won't be enough for a straight-up whole-house application which conforms to NEC 2008. To get that size generator to pass the code, you'll probably need some accessories that automatically shed loads, etc.

Skip is correct. Depending on your location you may be under the 2008 code. Your 16kw will be good for around 66amp continuous. Most homes with a 200amp service will not draw that large of a load but your electrician will need to do a load calculation on the house. If the calculation comes in over the 66amp. which I am sure it will, then you must start dropping off loads. OR you can follow 220.87 (2008)
