How much electric have you put into a single family residence?
The highest-profile piece of new construction in my small town has a requirement of 1000 amps. No electric heat, this is all for lighting, appliances, an elevator, large ceiling heaters in all the baths, and heat for the eleven steam shower units that are going in (eleven!).
Equipped with a SmartHome wiring package reputedly costing over a mil, the owner wants to be able to have one control input fire up all the lighting, everywhere, at once.

Someone has electric testosterone there. They probably drive a v10 crew cab to the golf course too.
"to the golf course"? What about his golf cart, probably one of the alcohol burning tractor pullers?
It's gotta Hemi.
He should probably cut his own deal with Hydro Quebec.
Is that going to be 3-phase?
I have heard in some areas that the large McMansions are getting 3-phase. The one I remember specifically was in the south so it had large AC loads.
I wish. Here, the DWP won't sell three phase to residential customers. It would be so much nicer to be able to use three phase motors. I could even invent my 75 HP shop vac.... ;-)

Has anyone seen the dog?
It's for the X-mas lights, you ninnys!

There are some clever merchandise folks out there to sell that type high priced system. Own house can do that with the '50s technology GE RR7 type relays aided by a $50 surplus computer and a few hundred diodes. Got a small simple rocker switch panel on the bed for on-off of any light, all outside, all inside, all upstairs, motion detector tie ins, etc. that was put together in 1973 (before the computer could do the tie ins to everything else and phone calls to check if anything left on, etc).
Our company factories still use the GE RR7 type relays, the facilities folks can control any light in any building across the entire United States and a few in Australia too. That overall system likely runs into the 7 figure category, but for a house???
PS: Near 40 years ago, first time I went to the wind tunnel and saw the power meter on the panel reading 41 MW, I was a little amazed. I'd love to see an energy plot for a month in whatever season for the 1 kA house, (= .24 MW) sounds like a 'mine is bigger than ours' event. There was a sign by the power meter that also said that at 40 MW (sign from 1950s) the draw could power 8000 houses at full peak power in the electric resistance heat area of Seattle at that time. Even at my most profligate usage (elec HP plus sometimes extensive welder usage) the power bill averages only 0.0002 MW).

Largest residential I've seen is 600A single-phase, in 7000 sq. ft. house in Phoenix. 600A meter base feeding 3 200A panels. Lots of air conditioners, you know.
OK, to put this in perspective,,,,,,,,
I figure 746 watts per horsepower.
240v x 1000 amp = 240,000 watts
240,000 watts / 746 = 322 horsepower !!!!!
Take the engine out of a D-9 and put a good load on it.
Is he going to have a back up generator??

Yeah, 120 of these View Image

To save money on the service connection by the utility, they're just going to throw some phone wire over the 175k volt high tension wires running overhead and use a xfmr to get it down to 240V
(grin)
That would work. It's only 3.64583 amps. 22ga will handle that, won't it?
We are working on a 12,100 sq ft, 2 story single family residence located on 35 acres on a lake. The load calculation for the service is 793 amps at 3 phase (all the AC units are 3ph commercial units).
The service for the main house is going to be 1000A, there are 3 guest houses (1500 to 2000 sq ft) and a maintenance building that is 2400 sq ft. Each building has its own 200A service. The house has an indoor pool, 3 kitchens, home theater, gym, conference room, elevator, 2 fish ponds and a waterfall all indoors!!
A 60KW Diesel generator will supply the main house and a 25KW propane generator will feed the heating systems and refrigerators for the guest houses.
We met with the utility company and they are treating it like a subdivision, so far we have over 8000' of misc PVC conduits providing for UG service, CATV, phone, security and data.
The entire job is design build, cost plus, and we get to sell the customer the latest and greatest!!
