### Do you have to use a transformer if your device have 900 Watts 220 V and 60 Hz with 7.5 amps?

If your device uses 900 Watts at 7.5 Amps, then it requires 120
volts. If you want to use it where the supplied current is 220
volts, then you'll need a transformer - but only if the device can
operate on 50 Hz. Most places that use 220 Volts supply it at 50
Hz. If your device says it can operate on 50 Hz you can use a
transformer.

### How many watts can a 20 amp breaker handle?

Answer for USA, Canada and countries running a 60 Hz power
supply service. Watts= voltage X amps At 120 volt total watts would
be 2400 at 20 amps. The electrical code states that circuit
conductors that are fed by this breaker on a continuous load can
only be loaded to 80%. #12 wire rated at 20 amps, derated to 16
amps continuous = 16 x 120 = 1920 watts, #10 wire rated at 30 amps
derated to 24 amps continuous = 24 x 120 = 2880 watts. On load
calculations this derate should be taken into consideration. To
maintain the required wattage needed for the load the wire size
and/or the next size breaker may be needed.

### How many amps does a hair dryer use with 25 volts 60 hz and 1500 watts?

Amps = Watts / (Volts x Power Factor). Now a hair dryer has a
motor and a resistive heater so if we assume a PF = .8 the answer
is:
1500 / 20 = 75 amps.
Since it is unlikely that you have a 75 amp hair dryer you must
mean 125 volts. The answer for that would be 1500 / 100 = 15 amps
which is still high, but believable. If we assume a Power Factor of
1 and ignore the motor contribution to Power Factor we have 1500 /
125 = 12 amps.

### Is 50 Hz the same as 50W?

###### Asked in Home Electricity, New Electrical Work, Modification of Old Electrical Work

### How many watts is 60 Hz 5 amps?

That depends on how much voltage is applied, because Volts x
Amps = Watts. So find out your Voltage and multiply it by the
amperage to get your wattage.
60Hz is standard for AC (hence the term Alternating Current) and
used for long distance power transmissions and even household
currents. Usually what is coming out of the socket is around 120
Volts (240 for appliances and other countries). So applying this
formula to this is simple: 120Vx5A=600 Watts or 240Vx5A=1200 Watts.
So on so forth...
Simply multiplying volts times amps gives what's called
Volt-Amperes or apparent power. Volt-Amperes equal watts (real
power) in largely resistive circuits. Circuits with motors,
transformers and inductors have power factors that
must be taken into consideration when calculating watts. For
example, in a motor circuit with a power factor .6, the watts would
be Volts X Amps X .6

### Will an American electrical appliance get ruined if fed 100 watts by a converter in Europe?

The amount of watts AVAILABLE to an appliance is not so
significant as long as there are ENOUGH watts. Three things are
important when determining what U.S. appliances can be used in
Europe with converters: 1. Voltage. Most U.S. appliances operate on
110 volts. Your converter must be capable of delivering 110 volts
to your appliance. 2. Current. Volts X Amps = Watts. It's a simple
formula but it will determine whether your appliance will operate
on a converter or just be frustrating. While volts is the
"potential", Watts is a measurement of energy. It can be the energy
the appliance uses or the energy that the converter delivers. If
the appliance uses 200 Watts a 100 Watt converter will not work,
either the appliance or the converter will fail. 3. HZ. While most
appliances are not so fussy, some devices require that the
electrical source be 60 HZ. Europe is 50 HZ and as such will cause
some problems with appliances that require 60 HZ. FYI, HZ is the
number of times per second that an electrical source reverses
voltage. Commercial power is delivered as "alternating current",
since that is the only way transformers can function. Europe has a
different standard so make sure your appliance will operate on 50
HZ before you take it all the way over there. If the appliance does
not list the energy used in Watts, it should be there in Amps, so
you can use the formula above to figure out the Watts that you
need. Good luck, and have a nice time in Europe.

### I need to replace a pond pump which says its 115v and 80hz. the newer pumps are measured in amps and watts. How can I tell from this info how many amps or watts?

I have had success with Pondmaster magnetic pumps. I suspect
that your 80 Hz description is really 60 Hz. The important thing in
pond pumps is how many gallons per hour you want to pump and how
high you want to pump the water. Not knowing your application it is
hard to size a pump for you. The 115V tells us nothing. The
physical size of your pump may be a clue. You should be able to get
a submersible pump for under a hundred dollars. Make sure the
pre-wired cord is long enough to reach your power source.

### What size wire should be used for a 2000 watt 240v electric heater?

Answer for USA, Canada and countries running a 60 Hz supply
service.
Wire size is based on the amperage that the device draws. To
find the amperage of any device use the following equation, Amps =
Watts/Volts 2000/240 = 8.3 amps.
A #14 copper conductor with an insulation factor of 90 degrees C
is rated at 15 amps.
