# Is a motor that uses 17 amps to much on 20 amp fuse?

yes

for continuous duty it must be at least 10% larger than the normal load

they usually get you on water heaters that take 28 amps need to put those on a 40A with #8 wire not good on the 30A

now if a motor rated fuse and nothing else will ever be on the circuit you can probably be correct with a 17 amp fuse and that is suitable for all the motor overload and locked rotor protection

and it will provide 80 amps for starting

### What size circuit breaker do you need for a 40HP motor?

Read the specification plate on the motor to determine the amount of current that the motor uses, as well as the voltage and phase. Most likely, it will be a 3 phase motor, so you can't simply connect it to your house wiring, but without sufficient information, it is impossible to tell you all of the specifics. <<>> The code book rates the amperage of a three phase 40 HP motor by different voltages. at…

### How many amps does a 1998 ford fuel pump use?

The factory pump uses 6 to 9 amps depending on the condition of the pump. A worn pump uses more power of course. I don't know what problems if any you are having but if you blow a 10amp fuse then change the fuel filter, a pluged filter will make your pump work much harder. Still blows? Then time for a new pump. Aftermarket pumps such as a Walbro pulls almost 15 amps.

### How much more electric will you use with a 1000amp motor vs a 750 amp motor?

Assuming the same voltage and power factor for the two motors. Watts = Volts x Amps x PF so the power of 1000 A motor is Watts = 1000 x V x PF and the 750 A motor is Watts = 750 x V x PF. So (Watts for 1000A) / (Watts for 750A) = 1.33 This means the 1000 A motor uses about 33% more electricity than the 750 A motor.

### What is a time delay fuse used for?

A standard fuse will blow in just milliseconds when excess current flow or a short is detected. A time delay fuse on the other hand may take 5-10 seconds to blow under the same conditions. You would want to use a time delay fuse in a device that uses lots of current at startup but then uses less after it is started. An electric motor or compressor is an example.

### What size wire and breaker is needed for a single phase 240 volt 5 hp well pump?

Answer for UK, Europe and countries running a 50 Hz supply service. 5 HP is equal to 3730 watts. Assuming that the motor is 90% efficient it uses 3730/0.9 or 4144 watts of power. If its power factor is 0.75 it uses 4144/0.75 or 5526 VA so the current is 5526/240 = 23 amps. The wire size would be 4 sq. mm. and the breaker should be set to at least 30 amps. <<>> Answer…

### Where is the fusible link in a 1996 Ford Contour and how hard is it to replace?

If there were fuse links on the car, there would not be just one, there would be several, but the Contour doesn't use any "fuse links." It uses fuse link cartriges. These are large fuses in the engine compartment fuse box that have clear windows on top. To replace the lower amp fuse cartridges, simply pull them out. The high ampere fuse cartridges(80 amps and above) are held in with screws on each blade terminal.

### How do you work out how much electricity an appliance uses?

There should be a label on the appliance that gives the amount of energy/wattage it uses. it could be on the bottom, side, inside, etc. If the only thing listed is "amps" you can multiply the number of amps x 120 to find out the wattage. The wattage number listed is the maximum amount the appliance uses, a refrigerator listing 500 indicates that is the amount expended when the compressor is operating.

### Difference between s type and t type fuse?

Your "T" type fuse (aka Edison type) has a base similar in appearance to a standard light bulb. Used mainly in older houses. The "S" type fuse (aka Tamper proof) has a smaller base and uses various sized adapters for the different fuse amperage ratings. In other words, a "S" type fuse rated at 20 amps would not fit into a socket that requires a 15 amp rated fuse.

### How many amps does a 3 phase 25 hp motor use?

it uses 45A at 415V in pakistan and starting current might be near 60A. <<>> The equation you are looking for is, Amperage when horsepower is shown; HP x 746/1.73 x V x %eff x pf. As you can see that an answer can not be given without the voltage of the motor being stated. Once you have the voltage use the formula. Use .89.5 for the % eff of a standard 25 HP motor…

### How many watts does a 54 inch television have?

you have to know how much voltage it is plugged into and how many amps it consumes. voltage x amps = watts. Look on the electrical plate on the back of the TV. for example in the US it might be 120 volts x 5 amps = 600 watts or .6 kilowatt hour (about 6 cents per hour). This tells you how much electricity the TV uses, not how many it has.

### How much is the maximum power for an iron?

If you mean an ironing board iron then you have to consider its a household item. The manufacturer isn't going to make something that will be blowing fuses. The typical outlet is 110 volts and the typical fuse is 15 or 20 amps. So in order not to blow a 15 amp fuse the power used by the household item has to be less then the power that would blow the fuse. You get this…

### Are electric baseboard heaters efficient?

Amps and Watts measure different things. An Amp is a measure of electrical current and a Watt is a measure of Power. Which ever device draws the higher amperage will be the one that uses more electricity! Hence the 240 watt heater draw less amps even though it uses more watts: Volts Watts/Electical Current Amps/Power example heater 240 volt draws 2000/1000 watts - but uses 8.3/4.2 amps example heater 120 volt draws 1500/750 watts…

### How much kilowatts of power does a 1.1kw motor use per hour?

If the "kilowatt" is something the motor uses whenever it's running, then the same unit can't measure something that gets tallied up over time. The kilowatt is the unit of power. Power is the rate at which energy is used. The motor uses energy at the rate of 1.1 kilowatts. You're asking for the amount of energy the motor uses in one hour. The unit you want is the "kilowatt-hour". That's the total amount of…

### How much does an amp energy cosT?

Amps are only a measure of electric current and not energy. The energy is equal to the power times the time, and the power is equal to the volts times the amps. So to find out the cost, you need the voltage, the current and the time. As an example 240 volts at 10 amps is 2.4 kW, and when run for one hour that uses 2.4 kWh (or Units) of energy.
