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

How many amps does a 12 volt boat trolling motor use per hour?
You asked the wrong question. You need to know how many amps the motor uses. Then you can multiply amps times volts and get watts. Then you can multiply watts by hours and get watt hours. (For house electricity you pay for kilowatt hours.) A kilowatt is 1,000 watts.
What size fuse is needed for a 3kw heater?
A 13 Amp fuse (brown) is needed for a 3kw heater. <<>> Answer for USA, Canada and countries running a 60 Hz power supply service. 3000 watts at 120 volts = 25 amps, 3000 watts at 240 volts = 12.5 amps.
What volt circuit is needed for an 8.5 amp electric motor that uses 550 watts in 1 hour?
The time is immaterial. A 550-watt motor operating at 8.5 amps needs a voltage of 550/8.5 volts.
How many amps required to run 10 ton air conditioner?
Your question is incomplete, but given the information presented if your motor was 100 percent efficient the current drawn by each phase would be 8.97 amps. No motor is 100 percent efficient so this number will not be the real world representation of your motor. answer= (746 w * 10hp) / (480 volts * Root 3) = 8.97 amps
How do you work out how many amps a forty watt bulb uses?
figure out how many amps are in a watt and x by 40
What size of circuit breaker do you use for 25amperes induction 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 200 volts - 120 amps, 230 volts - 104 amps, 460 volts - 52 amps and 575 volts - 52 amps. A breaker for a motor has to be sized to 250% of the motors full load amps. Also the wire size for a motor has to be 125% of the motor full load amps.
How many amps in a Playstation 3?
It uses 2 amps

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.
A coffee maker uses 7 amps of current and 110 volts. How much power does it use?
770
How many amps does a toaster use?
a regular toaster uses about 12.5 amps
What size fuse is needed for a 3kw heater?
A 13 Amp fuse (brown) is needed for a 3kw heater. <<>> Answer for USA, Canada and countries running a 60 Hz power supply service. 3000 watts at 120 volts = 25 amps, 3000 watts at 240 volts = 12.5 amps.
How much energy does a 75kW motor use?
Multiply 75 kW by T hours of use = 75T kWh, which is how much energy the motor uses.
What amps did avenged sevenfold use on nightmare?
The only amps a7x uses is the Marshall jcm800
What is the three uses for energy?
the three uses of energy are voltage, amps, and resistanc
What volt circuit is needed for an 8.5 amp electric motor that uses 550 watts in 1 hour?
The time is immaterial. A 550-watt motor operating at 8.5 amps needs a voltage of 550/8.5 volts.
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 and .89 for the power factor of a standard 25 HP motor. Using the above answer's voltage, the motors amperage equals 32 amps. A motors starting current can reach 300% on start up. The starting current can reach 96 amps instantaneous until the motor amperage drops to its run amperage.
