How many volts does it take to make 4000 watts?

There is not enough information to answer your question directly... In order to determine how many volts it takes to make 4000 watts, you also need to know how many amperes there are. That is because watts is volts times amperes. For example, if you had a 120V system, you could divide 4000 watts by 120 volts to get 33 1/3 amperes.


What type of home appliances will a 4000 watt generator run?

At 120 volts the generator will operate any appliance up to 4000 watts. If your generator has the ability to output 240 volts it will also output up to an maximum of 4000 watts. Amperage wise 120 volts at 4000 watts will equal, I = W/E, Amps = 4000/120 = 33 amps. Likewise 240 volts at 4000 watts will equal I = W/E, Amps = 4000/240 = 16.6 amps.Check the appliances that you would like to plug into the generator for either amperage or wattage. These values will be found on the appliances manufacture's nameplate.
