What size wire and breaker for a 7.5 hp motor?
For a 7.5 hp motor operating at 240V, you would typically use a 14-gauge wire and a 40 amp breaker. However, it is best to consult the motor's specifications and the National Electrical Code to determine the exact wire size and breaker needed for your specific setup.
What size breaker for a 5 hp table saw motor?
20 amp should do ya.
What size breaker is needed for a 125 hp motor?
It depends on what the amperage of the motor is. The motors amperage depends on the voltage of the motor. The higher the voltage the motor operates on the lower the amperage. So unless the amperage from the motor's nameplate is stated an answer can not be given.Just remember that the feeder capacity to the motor has to be 125% of the motors full load amperage and the breaker protecting the conductors to the motor has to be rated at 250% of the motors FLA. This higher breaker size allows the motor to start without tripping a normal size breaker that is rated for the lower conductor size.
Is a one half HP motor sufficient to run a dehumidifier with 15 Amps and 115 Volts?
A 1/2 HP 115volt motor draws 9.8 amps. This is a nominal book amperage for a 1/2 HP motor, check the nameplate for an accurate value. A breaker, to protect this size motor, has to be rated at 250% of the motors full load amps. In this case a 25 amp breaker in needed. If using the actual nameplate amperage, multiply it by 250% to find the size of the breaker to use. If the motor used 230 volts as a supply a two pole 15 amp breaker would work.
How do you calculate breaker capacity of 10 hp three phase induction motor?
The first thing you have to do is find the full load amps of the motor. The wire size feeding the motor has to be 125% of the full load current. The breaker is usually 250% of the full load current. If the voltage and amperage had been added to the question the exact breaker size could have been calculated.
What size time delay fuse do you use on a 40 hp 230 volt 3 phase motor?
The electrical code book states that a 40 HP 230 volt three phase motor draws 104 amps. For that motor the wire must be rated for 131 amps, Non time delay fuses at 300 amps, time delay fuses at 175 amps or a 250 amp circuit breaker. When calculating wire sizes and motor protection the motor's full load amperage should be taken from the motor's nameplate.
What generator size is needed for 40 hp 480 volt 3 phase motor?
probably about 50 hp depending on how reliable the efficiency ratings of the various manufacturers are
How many amp circuit breaker for 3 hp 230 volt motor?
16A

What size breaker for a 20 horse power motor with 3 phase 208 volts?
The question is impossib;e to answer without knowing the supply voltage. <<>> What ever the motors full load amperage is, the breaker has to be sized to 250% of that FLA.
Looking for a basic standard type answer to how many circuit breaker amps are needed per motor horsepower on 3 phase?
The main breaker is not based on the HP of the motor it is based on the FLA of the motor. Many different motors have different characteristics and all of the different motors have different amperages Once you have the amperage of the motor the breaker is 250% times the FLA of the motor.
