How to choose rating of contactor in star delta starter?
As well as motors, contactors also have kW and Ampere ratings. Have a look on the name plate of your motor and you will see its maximum current draw (amps). Select a contactor with a current rating greater than this.
How many wires to control a mechanically held contactor?
A contactor is a type of switch. However this switch uses electricity to power an electromagnetic coil to switch on or off power. Hence a contactor needs 2 wires - A live/hot wire and a neutral wire. Generally these are connected across the A1 and A2 terminals of the contactor.
How do you wire a three phase forward - reverse starter?
You start with a normal one way circuit consisting of a three phase contactor and an three phase overload in series for the forward circuit. Then you add the reverse contactor in parallel with the forward contactor but with line one and line two crossed over i.e. when the reverse contactor is made, line one of the supply will be connected to line two of the motor and line two of the supply to line one of the motor. The control circuit must also be interlocked to prevent forward and reverse being energized at the same time.
Will a 10 hp 220 volt motor draw large amounts of electricity?
A single phase 10 HP motor will draw aproximately 50 amps. A three phase 10 HP motor will draw aproximately 28 amps.
How many amps will a 24 volt dc motor draw if running at 12 volts?
Depends on how big the motor is. A stronger motor will draw more amps then a weaker or less efficient motor. For example a wiper motor draws far less then a starter motor.

Why does a slow motor create high amps?
Excessive resistance (drag), will cause motor to draw more amps (current flow) to operate.
If defective blower motor draws more current than a good motor because?
defective motor will not run, also cause the blower motor speed resistor to burn out and eventually blow the fuse. a motor with defective bearings will draw excessive current causing either the fuse to blow or cause the motor to overheat

What is the cause and solution of a 3year old can't draw?
It is natural that a 3 year old can’t draw. They don’t have the fine motor skills yet. They do scribble pictures and will try to write. Don’t push the child to draw because he/she is NOT developmentally ready to draw.

Can a 9 volt battery run a 12 volt fan motor?
Possibly but but not for long. The 12v motor will draw more current than the 9v battery can supply and the undervoltage will cause the motor to run hotter than normal thus shorting its usefull life.
What would happen if a 12 volt dc geared motor is run with 19 volts?
The motor would operate above its rated RPM. The motor would start to get hot as the current draw would be greater. This might eventually burn the insulation off of the windings and cause the motor to short circuit.
How do you connect float switches for a single phase motor through contactor and Over Load Relay?
you would wire a float switch into the control circuit i.e, the contactor coil (which is relatively low current but rated at least for the control voltage,, in most cases 120VAC). also in the same circuit would be the overload contacts. if the overload trips and/or the float switch opens then voltage is removed from the contactor coil
How many amps does a 15 hp motor draw?
To answer this question the voltage of the motor must be stated.
