All electric appliances use amps. Amps are a measure of current.
Not simultaneously because the total current must not exceed 20 amps.
When they give you WATTS the also give you VOLTS. Using some very simple math you can then figure out AMPS. WATTS = Amps x Volts
The formula to use is I = W/E. Amps = 20000/240 = 83 amps. Check the nameplate of the equipment that you want to connect to the generator. You can add equipment up to the total of 20000 watts or 83 amps.
To answer this question, you will have to add up the wattage's of the appliances that you think need to be run on emergency power. Keep in mind that an appliance with an electric motor will need more power to start the motor than what it operates at. Some amp ratings for fractional HP motors at 115 volts are 1/6 = 4.4 amps, 1/4 = 5.8 amps, 1/3 = 7.2 amps, 1/2 = 9.8 amps and 3/4 = 13.8. If the motors are 230 volts divide each amperage in half. To convert these motor amperage's into watts use the following formula. Watts = Amps x Volts. Starting an appliance with a motor on this size of generator will definitely drag the voltage down momentarily. The closer that you get to the generators capacity, the more the generator struggles to keep the voltage up. When the generator gets to this amount of overloading usually the generator breaker will trip. With too much load you can actually stall the generator and it will stop turning.
The sizing of a breaker is dependant upon the size of the wire it protects. The size of the wire is dependant upon what the load current in amps is. Without the amperage and wattage and the voltage of the appliances an answer can not be given. W = A x V, Amps = Watts/ Volts.
home appliances are rated by watts or amps
It depends on the amperage's of the appliances. You should be able to draw, Amps = Watts/Volts, 2500/120 = 20.8 amps at 120 volts.
For all intents and purposed the VA rating is the same as the wattage rating of appliances. VA is an electrical classification for Volt Amps. The formula for watts is, Watts = Amps x Volts.
Not simultaneously because the total current must not exceed 20 amps.
When they give you WATTS the also give you VOLTS. Using some very simple math you can then figure out AMPS. WATTS = Amps x Volts
Depends on how many, and what electrical appliances you have. If you are on 110volts, the current (amps) at any time are the kiloWatts you are running times 1000 (=watts) divided by 110
The basic equation is Watts divided by Volts equals Amps W/V = A
The formula to use is I = W/E. Amps = 20000/240 = 83 amps. Check the nameplate of the equipment that you want to connect to the generator. You can add equipment up to the total of 20000 watts or 83 amps.
each appliance should have a rating label showing the amps or watts used, Add up these figures to see if they exceed the capacity of the circuit. Amps =watts/voltage
If it is a 32-amp circuit you can use any appliance that takes less than 32 amps. That includes a 15-amp appliance. All appliances fed from that circuit must use 32 amps or less in total.
For calculation purposes R = E/I. R = 120/15. R = 8 ohms. This is hypothetical because of the internal components that make up most appliances.
It depends on the appliances themselves. If you use Ohm's Law, 120 volts multiplied by 20 amps you get 2400 watts. If these appliances are constantly used at the same time it is best to calculate your loads at 80%, in this case it would be 1920 watts. Look at the name plates on the appliances, the wattage on each will be listed.
