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.
How many amps per phase would a machine rated at 460 amps over three phases take?
It depends on the internal circuit of the machine. If it is star operated its full load current will be same as rated current. If it is Delta operated its full load per phase current will be as given below : Phase current = Line Current / 1.732
Can you use 240v appliances on 110v current?
No, the pin configuration of the 240 volt receptacle is different from a 120 volt pin configuration. This is a safety factor to prevent the wrong voltage being applied to the wrong device. If the appliance is an electrical heater, then operating a 240 volt unit on 120 volts would give you a reduced wattage factor. By halving the rated operating voltage you will only receive one quarter of the rated wattage from the unit. A 3000 watt heater at 240 volts will be reduced to 750 watts on 120 volts.
What amp circuit breaker should be used for a 120v 2.5 amp appliance?
If the appliance is just to be plugged into a circuit with multiple outlets then you just need to make sure that the sum of currents for all devices on the circuit are less than the rated current. A rule of thumb is total current should be no greater than 80% of the rated current. So you might have a 20 A breaker and several 2.5 A appliances on this circuit. If you have a dedicated circuit for the appliance you would only need to size the breaker for the maximum current being drawn by the appliance. If the appliance contained a motor then there might be a start-up current that might be as high as 15 amps so you would likely go to a 20 amp breaker for a safety margin. As a practical matter a dedicated circuit for an appliance in the 2.5 amp range should have a 15 amp breaker. I always install a 20 amp breaker just for added margin and possible future applications.
Why the rating of lightning arrestor is less than its rated voltage eg for 400 kv system it is 360?
The MAXIMUM rated voltage is the voltage at which the electricity would arc across the insulators The usage voltage is lower than the rated voltage (usually somewhere around 80% The lightning arrestor voltage is in between. It will not pass current at the usage voltage, but will pass current when the voltage exceeds the arrestor threshhold
Electrical appliances are rated in what electrical terminology?
Appliances are rated in UL (Underwriters Laboratory) listing, which is a safety testing laboratory, and are rated in watts.
What kitchen appliances use least amount of energy?
I would suggest looking for EnergyStar rated appliances. These appliances can use up to 30% less energy than other appliances. Here's some info from Wikipedia: http://en.wikipedia.org/wiki/Energy_Star
A Type of power used by appliances in the homes is what?
home appliances are rated by watts or amps
How much electricity can bee rated appliances save?
40%

If a centre tap transformer rated as 12V-0-12V 1Athen what will be the secondary current of that perticular transformer?
The output voltage of a transformer is not connected to the maximum rated current. You state that the transformer is rated at 12-0-12 at a current of 1A, therefore the maximum (rated) current on the secondary would be 1A. Normally, transformers are rated in VA (volt amps) which is simply voltage x current, the voltage across the two 12v terminals would be 12+12 volts, making the rating of the transformer 24VA.
What is rated voltage and current in transformers and how to calculate them if given 50k VA?
Rated voltage is the voltage at primary side. Rated current can be found from the equation, Rated Current= Output KVA / Output rated voltage
What is the difference between nominal current and rated current of circit breaker?
They are the same.
Why do some appliances produce heat than others?
The heat produced by appliances is in direct relationship to the wattage that the appliance is rated at. W = A x V.
What is a set-up transformer?
it is type of transformer which is used to step up the voltage from low to high value in order to make it applicable for high rated appliances. asha not only for high rated appliances but also for transmission...ashu
Why aren't series circuts a convenient way to wire a home?
There are two reasons. Parallel circuits apply the same voltage (the supply voltage) across each branch, which ensures that every appliance in a residence shares the same voltage (their rated voltage) in order to operate at their rated power. With a series circuit, the voltage across each appliance would be less than the supply voltage, and the appliances would not be able to develop their rated power. The second reason is that, with a series circuit, if one appliances stops working, there will be a break in the circuit, so all the other appliances will stop working too!
Why do some appliances produce more heat than others?
The heat produced by appliances is in direct relationship to the wattage that the appliance is rated at. W = A x V.
