∙ 10y agoLRA (locked rotor amps) is not used to calculate the breaker size. Breaker's are used to protect the size of the conductor that is connected to it. Motor calculations are based on the motor's FLA (full load amps).Conductor size is 125% of the motor's FLA.Breaker size is 250% of the motor's FLA.This is the only occasion when the breaker is sized larger that the conductors maximum amperage rating. This is due to the motor drawing up to 300 to 600% of its FLA when starting.If you state the motor's wattage, voltage or amperage this calculation can be calculated here.
AWG 10.
6 AWG.
As an electrician I can give you a vague answer with the information given. You need more specifics to do the calculations for the load amps and the supply voltage.The particular motor I looked at is a .6hp fan motor -4.0 Amps @ 230V(2650 x Full load amps ) divided by supply Voltage = MFDExample 2650 x 4amps = 10600 divided by 230volts = 46 MFDBut this is a general statement. The proper cap should be determined by researching the particular model you have.
The current draw is about 27 amps. A motor feeder has to be 125% of the motors full load amperage. 27 x 125% = 33 amps. A #8 copper conductor with an insulation factor of 90 degrees C is rated at 40 amps.
Need to know what the voltage of the motor is.
Its been a while since ive brushed up on my electricity knowledge, but im fairly certain that breaker capacities are based on amps. I think you would have to know the amperage of the motor before you were able to conclude what size you need.
The amperage drawn by a trolling motor will depend on the specific model and its power rating. To calculate the amperage per hour, you would need to know the wattage of the motor. You can use the formula: Amps = Watts / Volts.
i have 200 hp motor what i need cable size in 100 feet distance
To answer this question, wire size is rated in the amount of amperage that it can legally carry. The formula to find amperage when the HP is known is I = HP x 746/1.73 x E x %eff x pf. 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. Amps = 10 x 746 = 7460 = 7460/1.73 x 220 x .84 x .86 = 7460/275 = 27.1 amps. The electrical code states that a motor conductor has to be rated at 125% of the motors full load amperage. 27.1 x 125% = 33.8 A #8 copper conductor with an insulation factor of 60, 75 or 90 degrees C is rated at 40, 50 and 55 amps respectively.
If it's 120 v 4.8 amps that is about 450 watts.
Need to know what year and size the engine is that you are working on.

i do not know the size but the ampage is 10-25 amps
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.
A typical garage door motor uses about 3-5 amps while operating. This may vary depending on the specific model and size of the motor. It's important to check the motor's specifications for precise information.
A 60 horsepower motor typically requires a minimum breaker size of 100 Amps for normal operation. It is important to consult the motor's specifications or a licensed electrician to ensure the correct breaker size for safe and efficient operation.
