To answer this question the voltage of the motor must be stated.
The wiring should allow for 115 amps.
To start a 15 hp motor, you typically need a transformer that can handle the motor's starting current, which can be significantly higher than its running current. Generally, the starting current can be 6 to 8 times the full-load current of the motor. For a 15 hp motor, the full-load current is about 18-20 amps at 230V or 10-12 amps at 460V, so the transformer should be rated to handle at least 100-160 amps. Additionally, it's advisable to consult the motor's specifications and consider factors like starting method and application to determine the exact transformer size.
A 15 amp circuit breaker should trip at 15 amps regardless of the load voltages or impedances. If you have 277 volts and 7 ohms, the current would be 39.5 amps and a 15 amp circuit breaker should trip.
The formula you are looking for is I = kW x 1000/1.73 x E x pf. I = 1.5 x 1000 = 1500. 1500/1.73 x 400 x .86 = 1500/595 = 2.5 amps. A standard motor's efficiency between 5 to 100 HP is .84 to .91. A standard motor's power factor between 10 to 100 HP is .86 to .92. A feeder for a motor has to be rated at 125% of the motors full load amps 2.5 x 125% = 3.1 amps A #14 copper conductor with an insulation rating of 90 degrees C is rated at 15 amps.
At 600 volts the rule of thumb is one amp per horsepower. So a 20 HP motor would need 20 amp wire. The code book states that a 20 HP motor at 575 volts draws 22 amps. The conductor for a motor has to be 125% rating of the motors FLA (full load amps). 22 x 125% = 27.5 amps. A #10 copper conductor with a insulation factor of 60,75 or 90 degrees C is rated at 30 amps.
The current draw of a window motor typically ranges from 5 to 20 amps, depending on the vehicle and the specific motor design. During normal operation, the motor may draw around 10-15 amps, but it can draw more during initial activation or under load, such as when the window is stuck. It's important to check the manufacturer's specifications for the exact amperage of a specific window motor.
A 240V well pump typically draws around 10-15 amps.
The wiring should allow for 115 amps.
The amperage draw of a forced hot air furnace typically ranges between 5 to 15 amps, depending on the size and type of the unit. Smaller residential systems may use around 5-10 amps, while larger systems can draw closer to 15 amps or more. It's essential to check the manufacturer's specifications for the exact amperage of a specific model, as factors like blower motor size and additional features can influence the total draw.
Presuming single phase and 1500 rpm. Normal running current would nearly 10 Amps but varies considerably. A real cheap one running at 3000/3600 rpm could exceed 12 amps. At 240 volt, all should be run off 15 Amp line.
The amp draw for a Skil Saw, or circular saw, typically ranges from 10 to 15 amps, depending on the model and its motor power. Most standard models operate around 13 amps. Always check the specific manufacturer's specifications for your saw to ensure you have the correct information.
I have a single phase induction motor. It draws 8 amps on start up and climbs to 14-15 amps when I put a load on it. When I don't have a load it runs at 1 and climbs to 2-3 amps. It is normal operation for this motor to run at the lower number of amps with a load. But I don't know what is wrong.
The amperage draw of an iron typically ranges from 5 to 15 amps, depending on its wattage and design. Most household irons operate between 1000 to 1800 watts, which translates to approximately 8 to 15 amps on a standard 120-volt circuit. Always check the manufacturer's specifications for the exact amperage of a specific model.
A typical blower on high speed can draw around 10-15 amps, but this can vary depending on the size and type of blower. It's important to check the specific product specifications for accurate information.
The amp draw of a DeWalt compressor can vary depending on the model and specifications. However, most DeWalt compressors for residential use typically draw between 10-15 amps. It's important to check the specific model's manual or specifications for accurate information.
It's the amps that are controlled by the breaker not the volts. You can have a 600 volt 15 amp breaker, you can have a 347 volt 15 amp breaker. The breaker will trip when you exceed 15 AMPS.
