How many amps should a starter draw?
It depends on the size and type of the motor being started.
Can I use a 30 amp circuit with a 12 gauge wire to handle a tablesaw that runs at 13 amps under load but spikes above 30 amps on turning on as the 20 amp circuit kept tripping at turn on?
This is proper connection for a motor that has a full load amperage of 13 amps. The wire size for motors has to be 125% of the full load amperage from the nameplate on the motor. On a 13 amp motor this relates to 16.25 amps. The next wire size up from this current is #12 rated at 20 amps. If you are using a fractional motor starter switch to control this motor, the heater size for the switch should have a rating of 16.25 amps. The fusing for wire is 40 amps for non time delay fuses, 25 amps for time delay fuses or a 30 amp circuit breaker.
What size of wire and breaker do you need for a 10 KW electric furnace?
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.
What size Teck cable is required for a mini split heat pump that is 15 amps?
Two conductor and three conductor #12 Teck cables are rated at 20 amps. This size is one over from the 15 amp rated wire. This is because on motor loads the conductor size has to be 125% of the motors full load amps. Since all that was stated is 15 amps it is better to err on the larger size wire.
What is the start up amps on a 200 hp 3 phase 480 volt motor?
i have 200 hp motor what i need cable size in 100 feet distance
How do you size the circuit breaker feeding a soft starter for a 195A full load current induction motor?
Sizing circuit breakers for motors falls into a different category. Because of the inrush of current when the motor is in the stopped position, the breaker has to be sized to allow for this. Breakers usually are 250% of the nameplate full load amp rating. The wires that feed the motor are sized to 125% of the full load amps of the motor.
LRA is 134 AMPS. what size breaker should be used?
LRA (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.
For 225 kw motor what is the amps star and delte and what is the cable size required?
Need to know what the voltage of the motor is.

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.
Fuse size for 7.5 HP 3 Phase 440 Volt Motor?
The electrical code states that a 7.5 HP 460 volt three phase motor draws 11 amps. For fuse sizes, non time delay - 30 amps, time delay type D - 20 amps and if using a breaker it will be 30 amps. Minimum wire size is #12 and the maximum setting of overload devices will be 13.75 amps

What is the cable size for motor 15kw 440 volts connection?
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.
What size wire of suitable 13amp motor?
I would recommend you use AWG # 14 gauge which is rated at 15 amps.
Need to know wire size for 50 hp motor at 56.9 amps?
6 gauge if it is a very short distance.
