What size breaker for a 208 volt single phase motor that pulls 1.4 amps?

208 volts is not a common single phase voltage but you could just size your breaker to the capabilities of the conductor. 208 is normally a phase to phase voltage

Many 230 volt motors can be connected to lower voltage supplies. These motors can be connected to supplies of 208 and 200 volts. The code requirement is that the 230 volt full load amperage of the motor be increased by 10% and 15% respectively for wire sizing and breaker selection. To answer the question you will need a two pole 15 amp breaker.

For a 208 volt single phase motor that pulls 1.4 amps, you would typically use a 2 amp breaker for proper protection. This allows for a small safety margin above the motor's operating current to prevent nuisance tripping. Be sure to consult the motor's manufacturer specifications for the most accurate breaker size.

When are Capacitors used with single phase motors?
The capacitor is used to produce a phase shift to create a rotating magnetic field so the motor will start turning. 3-phase motors do not need one because of the phase difference inherent between the phases.While a capacitor connected external to the motor does affect the power factor of the overall system (as mentioned below), an internal start capacitor is not used for that reason in a single-phase motor.Another answerThere is inductive reactance and capacitive reactance. (Look these terms up, it is good stuff). Think of them as opposites in a sense. The operation of the induction motor is inefficient in a power factor sense due to electro magnetic field properties that affect the power factor in an inductive sense. The capacitor is an "offset" to the inductive reactance which, when sized accordingly, affects the power factor as a correction towards unity.
How many amp does a stock fan motor pulls on an 86 Pontiac fiero?
The stock fan motor on an 86 Pontiac Fiero typically pulls around 10-15 amps of current when operational. It's always best to consult the specific technical specifications or manual for precise information.
If an electrician have a circuit that pulls a load of 10 amps what size breaker must that circuit be protected by?
For a circuit with a load of 10 amps, a breaker of 15 amps should be used for adequate protection. It is important to choose a breaker size that is slightly higher than the load to prevent frequent tripping and ensure safety.
Would replacing an old 15 amp breaker stop the air conditioner and fan from throwing the breaker?
It is possible that replacing the old 15 amp breaker with a new one could resolve the issue of the air conditioner and fan causing the breaker to trip. However, it's also important to ensure that the electrical load from the air conditioner and fan is not exceeding the capacity of the circuit. If the problem persists after replacing the breaker, it may be necessary to consult with an electrician to assess the electrical system.
What size breaker should be used for a fridge?
A standard household refrigerator usually requires a dedicated circuit with a 15-amp breaker. Larger refrigerators or ones with additional features may require a 20-amp breaker. Always consult the manufacturer's specifications for the specific model to determine the appropriate breaker size.
What is the amperage of a 20 HP 240v single phase motor?
Typically single phase motors go up to 10hp. Wouldn't be very efficient at about 100 amps. A 20hp 3 phase motor at 230v pulls 52 amps. The 10hp single phase 230v pulls 50 amps.
Is there a square d with 2 pulls that will replace a single pull that is one half inch wide as you are out of room in your box?
Yes, Sq D makes a tandem mini breaker that will fit into a standard Sq D breaker slot.

How to change the speed of a three phase motor?
A typical 2 speed three phase motor will have 6 leads on the motor windings which will require 3 contactors to incorperate both the "high" and the "low" speeps. Inorder for the motor to run on "low" speed you need to have a contactor (c1) that pulls in for the L1, L2,L3 leads... that should achieve the "low" speed of the motor.. To achieve the "high" speed you will need a contactor (c2) to shun or short L1,L2,L3 together... and another contactor (c3) to pull in the L4,L5,L6 leads... to recap ... Low speed will requrie c1= L1,L2,L3 powered by phase 1, phase 2, phase 3 of the primary source voltage. High speed requires c2 to short or shun L1,L2,L3 together while c3= L4,L5,L6 to be powered by Phase 1, Phase 2, Phase 3 fo the primary source voltages. Be sure to check for proper rotation of the motor and by reversing any 2 leads of the primary source voltage you will change the rotation for the motor. This can also be done using two contactors by having L1,L2,L3 connected to the first contactor and also the additional contacts mounted on top of the second contactor. L4,L5,L6 are connected to the second contactor. The important thing to remember is to use an interlock which fits into both contactors when they are clipped together. This stops both contactors operating at the same time!!! ( the additional contacts mount on top of a contactor and are mechanically connected to it so that they act together)

What size amp circuit breaker should be used for a geyser?
Depends on how many amps it pulls and the size of the wire in the circuit.
Building wired for 120 60 Hz 1 phase you are looking at a grinder that is rated 360208-230460 Will this grinder work or will you need a dedicated lineput in?
Your building is definitely wired for 220v 60Hz 1 phase. The power company sends you two 110v lines that are 180 degrees out of phase. In your breaker box you've got two bus bars; one 110v line is wired to the left bar, the other to the right. If you want some 220v power for something like a water heater, you use a two-pole breaker. That pulls power off both bus bars. The grinder you're looking at is designed to run on three-phase power. If your property is zoned commercial or industrial, the power company will have to bring you the third phase, but it's not all that hard for them. You will also have to install a breaker panel for three-phase power, and that's not hard for an electrician. If you're in a residential area, you generally can't get three-phase power...the reason, of course, is that they're afraid you'll install a machine shop in your garage.
