Does anyone know how to figure out?

The problem isn't so much how many watts but what will you be running at one time.

I have a 5500 watt generator and a transfer box that has 6 lines/circuits on it. Window air conditioners likely will pull a bit of power but if it isnt running the same time as the freezer kicks in and the refrig., you'll be ok.

Start up on most appliances use more initially. My unit will run all the lights and outlets, as well as the sump pump, furnace blower and indoor refrig and microwave. Unfortunately, the furnace blower, microwave, and refrig are on the same circuit so if those units kick in at the same time, it will likely open a breaker. I can take care of the problem by moving the microwave to another circuit.

Since we are talking emergency up to 2 weeks, I'd make sure there was a transfer box installed so power wouldnt feed back into the house when the power is restored. Electrical company employees do not like to see generators running because they could get fried. I would also try to run the items only about 45 minutes and then shut items off for an hour or two. This will keep your fuel from being used up too quick.

5 gallons basically will only last about 8 hrs on 50 percent load, maybe a little more. I'd speak with an electrician for sure and he will give you better ideas. My set-up cost about 1100 dollars 8-10 years ago but that included an electrician installing a transfer box.

Wish you luck on this project. It is worth it and people in need will appreciate it, if you are willing to help others out.

Look at the power requirements of every electrically powered item that you intend to use during a time that public power supply will not be available. Notice that the items that use a lot of power may not be a necessity. Electric clothes dryers, toasters, electric cook stoves, electric heaters and other high end users of electricity should be avoided. Add the watts required for the operation of each unit that is a necessity. You will not ordinarily operate all of the units on your list at the same time.

Your local electricity provider can assist you with a reasonable estimate.

There are too many variants to really be able to tell you. You need to look at the tags on all the appliances, etc. that you might want to be running all at the same time, find out what they each draw for power even during initial start up(electric motors draw more power during initial start up than they do while running), and then take all that information with you or call Lows or somewhere. They will be able to figure what you need.

ask some body at Home Depot or Lowe's. I have a 6500 watt generator and I run my sump pump, freezer, refrigerator, TV and a light. We don't have an air conditioner, so you might need a bigger one

since i life in the eye of the storm for over 25 years in louisiana i always used this theory == have a big cook out when the storm enters the gulf drink all the beer in the fridge and than pack and haul butt!!! but if you insist i would go with at 10000 watts and have and automatic kick in installed -- you will have to test and service the generator monthly to keep it in running order!!!

Go with a 10,000 watt unit. It will use less gas per watt than 2 -5,000 watt units. Buy you're gas before you anticipate outage. Stored gas can go bad within a month. The window AC will use most of the wattage.

Good question I was wondering the same thing? We are going to buy one also. After no power during Ike we want one. Food spoilage was the big issue.

Hourglass is while the bust and hips are the comparable length and the waist is critically smaller than the hips. seems such as you are able to properly be extra pear formed. Examples: Hourglass: 36-26-36 Pear: 34-26-37

I think you will buy two, I know people who have generators, and they run their ice box and a light on one generator. Talk to the people at the home store and see if they can advise you.

And don't forget to fill up extra gas gans before the prices skyrocket and the lines at the pumps are around the block. Fill them up as soon as you get the gennies in. You can add Sta-bil to preserve the gas.
