Question

Why do major appliances such as electric stoves and clothes dryers require 240 v circuits that have large current ratings?

please help me!!

Answer 1

YOU NEED A SEPARATE CIRCUIT BECAUSE OF THE AMPERAGE
PULLED WHEN ITEM IS IN USE, IF NOT YOUR CIRCUIT
WILL TRIP FROM OVERLOAD

Answer 2

Because they consume lots of power.

A typical 100W light bulb consumes 0.83A of electricity at 120 Volts AC. The heating elements in a stove or a dryer have to get much hotter than that light bulb in order to cook your food and dry your clothes.

Why 240V?
Because Power = Volts * Current, so you would need twice as many Amps of current if you were using 120V. (That's also why overhead power lines are stepped up to several thousand volts.)

You may also notice that these heavy-duty appliances have special 3 or 4 prong plugs that are a different shape from the other ones you're used to. That is because they use 3-phase current. (Most of the things in your house use 2 of the 3 phases.)

Answer 3

The major appliances you listed require more power.

As others have said, power (in watts) is the product of volts times ampers.

While you could keep everything at 120V and increase Amps, it's not practical nor economical. Why? Because to carry greater amps, you need a larger wire.

It is easier to double the power by doubling the voltage. Otherwise, you would have to increase the wire size all the way back to the source (junction box) to carry the extra load.

Answer 4

I have given this thought too, why increase the Voltage when really the Amperage is what is the driving force, they could have low voltage and high amperage instead.

One socket could be maybe with a red caution sign high amp socket only for use with high amp appliances

I do like the answer above me pretty informative, I just have to wonder why the standard wasn't high amps low voltage, I think Tesla .said pretty much the same thing I read someplace.

Answer 5

via fact volts cases amps supplies power then for a given power a greater physically powerful voltage demands much less amps. decreased amps potential that the wiring would properly be lighter and consequently greater low-fee. it is applicable to the motor additionally meaning that the copper windings would properly be lighter.

Answer 6

i rated on all of those questions and i think you better call an electrician before you end up dead!
