Snip tool? What's that? I have Prt Scrn which puts the screen image on my clipboard. When I paste it to Word, it becomes a .doc file.

If running Windows I think it is already an included app with Windows 8 and higher. If you don't have it it is a free app in the app store. Allows you to capture a portion of or the entire screen and convert to an image file.

I am using an old computer, pre Windows 8.
I know there is a way to do it on this machine, but IIRC, it's kind of a PITA.

Looks like it is included with all Windows versions Vista and later.

Look at the free MWSnap. I've found it superb; I know it works with XP and 7. Creator's website, http://www.mirekw.com/winfreeware/mwsnap.html does not address 98 or ME.

I figured out how to do it with PS.

That still doesn't show demand. The number of kWh used in an hour will not show a momentary spike in demand when (for example) a large motor starts up. For that you'd have to have data with much higher resolution.
What you really need is continuous current and load traces.

I totally agree. My peak showed about 700 watts for one hour. I know a 700 watt generator wouldn't start up my shallow well pump or my 10,000 btu air conditioner. I would even consider 7000 watts to be conservative for a whole house generator here.

I thought I would give you guys an update on the generator situation. I suggested to the GC that we do a study to see how much power is actually being used and then add some for the new additions. Instead, GC decided to consult Kohler's website where they have a handy dandy generator sizing calculator. Based on that we are buying a 48Kw liquid-cooled beast. That's 200 amps on a 225 amp service. No doubt all power requirements will be covered in spades. No worries about the neighbors walking over with extension cords. I haven't heard what the total onsite propane capacity will be. I expect it to be huge as well.
It's going to be fun to wire.

makes perfect sense to let the company selling the generator tell you how big a one you need :slaphead:

Kohler: How big is the service?
Contractor: 200
Kohler: You need a 48kw
Contractor: But I haven't told you what's connected..
Kohler: Forty. Eight.

I'm having a hard time getting any answers from the county planning people. Can anybody tell me what the usually setback from property lines for a generator is? How about height of the pad? The property is on a lake. It's in a 500 year flood zone. Does it need to be elevated for flooding purposes?

set backs are usually determined by the town/city. lots of local municipalities provide their rules/by-laws on municode. you can use the ctrl+f function of your web browser to search. might be worth checking there. :thumbsup:

I finally got an answer today. I had to go down to the permit office (downtown, metered parking) and wait for a zoning person to talk to me. Apparently, they can ignore emailed requests for information. She showed where the regulations were and then interpreted them for me. It varies by town and zoning. In my case 15 feet from the side property lines, and 50 feet from the front and back property lines. Rules are the same for the buried propane tank(s).

I think some places you basically can be same distance from back property line as the sides, and can be nearly right up to the line with some things.
Front is usually is 50 feet or so.

Is there a max size for a tank, whether above ground or buried? If the property were large enough to accommodate a 10,000 gallon tank, someone is bound to express some concern.

Yes, often there is maximum size for such tanks, especially on residential property. Non residential - distance to other structures may a big factor but often is less restrictions on size otherwise.Is there a max size for a tank, whether above ground or buried? If the property were large enough to accommodate a 10,000 gallon tank, someone is bound to express some concern.
We had a fire several years ago now at a tank at a plant in a City in this region not sure how big the tank was - probably bigger then 10,000 though. Fire was at a point in piping that was discharging gas for whatever reason - and it was right under one of the end caps of a horizontally placed tank.
This was a city of ~25000 people and they immediately started evacuating about 1/3 of the main portion of the city - just in case.
Was a really cold day on top of everything - they kept spraying water on the end of the tank just to keep it cooled, finally got a firefighter to crawl up to the tank and close a valve to end the main excitement of this incident.

Luckily for me, the propane tank is not in my scope of work. I would assume the gas contractor would know the rules for that and not install something that would fail inspection.
