hello all,
we will soon have a modular delivered to our rural area and want to have a
liquid-cooled, propane, automatically kicks on, one-phase, standby electric
generator sufficient (prob ~30kw) to power the whole house without
restriction (200amp service- incl well pump; electric range; frige &
freezer; TVs; computers; geothermal heating/cooling/water heater equipment;
etc).
all the electricians the construction supervisor has contacted have all
quoted $5,000+ labor to hook up our supplied materials- supposedly to wire
the individual circuits to be powered.
isn't there a way to have an automatic switch in line after the meter and
before the house's panel- thereby bypassing the labor to install individual
circuits? if so- what brand of switch, would i need to get an even bigger
generator to avoid any overloading...
thanks in advance,
kurt

Dunno if the generator's big enough, (200 amps is 48KW) and yeah,
you'll need a 200A Automatic Transfer Switch. Plenty of them out
there. Google is your friend. You might want to confirm that your
ATS is compatible with your generator (or buy them both from the same
vendor) to avoid finger pointing exercises after the fact.

thanks for the replies.
would this 40kW Liquid Cooled Generac Generator Model 04993
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category 772&item840967686
be sufficient for our needs? it replaces their previous 45kW model 04373.
what would a reasonable installation expense be?
thank you,
kurt

Since he started a new thread, we don't have the context from his
previous post, where he said:
/*
(200amp service- incl well pump; electric range; frige &
freezer; TVs; computers; geothermal heating/cooling/water heater
equipment;
etc).
*/
Would a 40WK generator handle a 48KW peak load? Dunno, but I'd put a
peak-recording clamp-on ammeter on both legs of the main feed for a
day or two, and try it with everything on, before I could say for
sure.
What's wrong with manual load management? Why coudn't you (for
instance) forgo the use of the electric range and the (if electric)
clothes dryer when on the generator?
Installation costs will vary. My $5K 8.2KW NG generator with ATS cost
about $5K to install, but I had some esoteric requirements (load
shedding, etc). Get quotes from the installers...
