A kw, or Killowatt = 8.7 amps. So, 30 x 8.7 = approximately 260 amps.
A wall Air conditioner draws about 12-15 amps. A refrigerator about 10-12 amps, a 100 watt light bulb .87 amps or less than 1 amp.
Houses typically have either a 100 amp main breaker or, 150 and up. In the old days, 60 amps was common.
Your answer is, as many houses as it takes to use 260 amps.
If it's for a generator, as backup, 4-8 houses to keep the required things working.
BUT use a large cable to run the power. 260 amp cable is about 3 ought size.
Good luck.

8 watts for 30 minutes is how many kilowatt hours?
30 minutes is 0.5 hours. 1 kilowatt = 1000 watts, so divide both sides by 1000 and you get .001 kilowatts = 1 watt So 8 watts x 30 minutes = .008 kilowatts x 0.5 hours = .004 kilowatt hours.
If you run a 100 W light bulb for 30 days continuously how many Joules of energy have been used?
100 watts = 0.1 kilowatts. 0.1 kilowatts for 24 hours a day for 30 days is 0.1 x 24 x 30 = 72 kilowatt-hours.1kWh (one kilowatt-hour) is 3.6 MegaJoules of energy. 3.6 x 72 = 259.2 MegaJoules of energy used.(This is assuming a pure, constant, clean flow of electricity, it's an incandescent bulb with no power factor or electronic ballast/transformer efficiency to take into account!)
How much does it cost to use a hair dryer for 30 minutes?
The price of electricity is usually quoted per kilowatt-hour. If your hair dryer uses 2,000 watts for 30 minutes, that is one kilowatt-hour.So take the wattage rating of your hair dryer and divide by 1000 to get kilowatts. You specified 30 minutes, which is 0.5 hours; multiply the kilowatts by the hours to get kilowatt-hours. Then multiply the price per kilowatt-hour of your electricity to get the total cost.For example: 1500-watt hair dryer for 30 minutes at $0.12/kW-h1500 watts ÷ 1000 = 1.5 kilowatts30 minutes = 0.5 hours1.5 kilowatts x 0.5 hours = 0.75 kW-h0.75 kW-h x $0.12/kW-h = $0.09
How many kilowatts does it take to run a thirty horsepower motor for one hour?
The Watt is the basic unit of electrical power. It has nothing to do with time. 1 kilowatt is 1000 watts. The conversion between electrical power and mechanical power is: 1 HP = 746 watts (0.746 kw). So it only takes 373 watts (0.373 kw) to run a 1/2 hp motor at the rated hp for as long as you want. Now, if you are wanting to know the amount of energy consumed by running this motor for 1 hour, simply multiply the 0.373 kw by 1 hour and you will see that it consumes .373 kwh (electrical energy is time-related, electrical power is not). Hope this helps...
How much work does a 100 watt light bulb do when it is lit for 30 second?
3000 joules(J)
77000 watts for 30 days is how many kilowatt hours?
Convert the watts to kilowatts, and the days to hours. Then multiply kilowatts x hours to get kWh.
How many kw are 30 Mgw?
1 Megawatt = 1000 Kilowatts so 30 Mw = 30*1000 kw = 30,000 kw.
How many houses in England?
About 30 million
8 watts for 30 minutes is how many kilowatt hours?
30 minutes is 0.5 hours. 1 kilowatt = 1000 watts, so divide both sides by 1000 and you get .001 kilowatts = 1 watt So 8 watts x 30 minutes = .008 kilowatts x 0.5 hours = .004 kilowatt hours.
How many kilowatts does it take to run 100 amp home?
A three wire home distribution service rated at 100 amps has a wattage capacity of;From L1 to L2 at 240 volts x 100 amps = 24000 watts or 24 kilowatts. From L1 to neutral at 120 volts x 100 amps = 12000 watts or 12 kilowatts. From L2 to neutral at 120 volts x 100 amps = 12000 watts or 12 kilowatts.

How many houses are in the Arizona state legislature?
The Senate and the House of Representatives.
A 100 watt light bulb left on for 24hrs how many kilowatts does it draw in a thirty day period?
1 kilowatt is equal to 1,000 watts, so a 100 watt bulb uses .1 kilowatt. Technically, your home or business meter base measures kilowatt hours, meaning that it measures both the kilowatts and the amount of time. If you turn on 10 100 watt bulbs for 1 second, that would be a kilowatt, but the amount of power use would be insignificant. So... To calculate the kilowatt hours: .1 kilowatts (from above, knowing the energy use of the bulb) Multiplied by 24 hours in a day Multiplied by 30 days... .1(kilowatts) * 24(hours)* 30(hours in a day) = 72 kilowatt hours
How many kilowatt hours - KWh - are used to light a 30 watt light bulb for 1 hour?
A kilowatt is 1,000 Watts. 30 Watts is equal to 0.03 kilowatts. A kWh or kilowatt-hour is the rate of electrical usage. It is a measure of kilowatts used per period of time (1 hour). 1 kWh is 1 kilowatt (1,000 watts) for 1 hour. So, multiply your 30 watts (0.03 kilowatts) by 1 hour to get kWh. =0.03 kWh In about 33 hours and 20 minutes, this lamp would use 1 kWh.
How long does it take for a new element to heat in a 30-gallon water tank?
This depends how many kilowatts are running through the element, but it can take anything from one to two hours.

24 houses have pumpkins. 6 houses don't have pumpkins. 24/30 = 80% have 6/30 = 20% have not
If 15 carpenters can restore 45 houses in 90 days At the same rate 5 carpenters can restore 30 houses in how many days?
15 carpenter, 45 houses, 90 days. Each carpenter restores 3 houses in 90 days. 5 carpenter restore 15 houses in 90 days. Therefore, 5 carpenters restore 30 houses in 180 days.
