Can you run 3 appliances 10-15 amps each through an extension cord with multiplug that is rated for 20 amps?
Not simultaneously because the total current must not exceed 20 amps.
Why are some appliances rated in watts and others 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
How much can a 20 kilowatt generator power a home's furnace and vital appliances?
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.
What appliances will a 5000 watt generator run?
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.
What size amp breaker you need for a ac and a heater unit?
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.
A Type of power used by appliances in the homes is what?
home appliances are rated by watts or amps
How many home appliances can be run using a 2.5 KVa generator?
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.
What is the VA rating for common appliances?
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.

How many amps are needed for 24hours?
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
How can you calculate which fuse to use for different appliances?
The basic equation is Watts divided by Volts equals Amps W/V = A

How do you decide which appliances can be used in a circuit without overloading it?
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
Can you use32amp circuit for a 15amp appliance?
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.
A 120 volt appliance requires 15 amps to operate - what is the resistance of the appliance?
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.
Can you use a toaster oven and a coffee pot on a single 20 amp circuit?
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.
