There are at least 5 different definitions for slightly different BTUs.
One of them says that 1 kWh = 3412.14 BTUs. Let's use that one.
1 kWh = 3412.14 BTUs
12 kWh = 40,945.68 BTUs
2.2 gallons per hour at full load using Winco-Honda 12kw standby generator model PSS12H.
12kW equates to about 16.1hp

It depends on the voltage and on whether it's single-phase or three-phase.
There is no choice of what voltage that you are supplied for your home. You are governed by what the utility company in your area supplies.
The breaker protects the wiring not the boiler. 12,000 watts at 240 volts will require 50 amps. So, you will need a 60 amp breaker using AWG# 6 wire on a dedicated circuit.
To completely power everything you would need a 12KW generator. However in an emergency you can live with a 5.5KW generator. You will not however be able to run an electric oven at all. To run an electric water heater almost everything else will have to be shut off. You will have to ration the power.
Charges for power are mentioned in kilowatt hours. You need to know how much you are being charged for kWhr. 12kW hrs every day it comes on
This question is akin to "How many faucets can you put on a pipe?" You can put as many as you want on, but how many you can use is another story. Calculate how much power you can draw with these transformers. That will tell you how many you can connect.
Answer for USA, Canada and countries running a 60 Hz supply service.For dwellings: 21kWFor non-dwellings: 46.8kWAs always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
As with most items made in China, one of the premier advantages of buying a Chinese diesel generator is that it will be cheaper. The 12kw generator is actually the most popular choice at the moment. Also, Chinese generators are said to be more reliable because they are "over designed" (www.backuppowersystems.com).
a 1000 watt bulb used for 24 hours consumes 24,000 watt-hours of energy, or 24 kilowatt-hours or kWh. That is also described as 24 Units, each costing around £0.15. So the toal cost would be about £3.60.
