Wiring of pressure switch on an air compressor
Take a wire from one of the line terminals L1 to one side of the contactor coil. Take another wire from the second line terminal L2 and put it to one side of a N.C. contact on the overload block. From the other side of the N.C. contact on the O/L block take a wire to the N.C. terminal on the pressure switch. From the other side of the N.C. contact on the pressure switch terminal connect the wire to the other side of the coil. This configuration will be using the same coil voltage on the contactor as that of the supply voltage.
Connect the motor leads to T1 and T2 on the bottom end of the overload block.

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

∙ 10y agoWiring a 230 volt single phase outlet requires aligning the proper color wires. Regardless of the voltage a ground is always prudent to use. In addition, a box and end caps should be used for safety.

∙ 12y agoA rather confusing question, as you do not make clear what you are asking!
However, if you mean, "How do you connect a single-phase, 230 V, load to a three-phase supply?", then you connect the load between any one of the three line conductors and the neutral conductor.
If you mean, "How do you connect a load to a 230-V supply?", then you connect it between the available line conductor and the neutral.
Any earth connection should be connected to the protective (earth) conductor. Only the line conductor should be protected using a fuse or circuit breaker.

How many amps will a 3 hp motor pull on 230 volts?
It depends on the voltage of the motor, and whether it is single-phase or 3-phase. A 120 VAC 2HP single phase motor draws almost 20 amps, a 240 VAC single-phase 2HP motor draws about 10 amps. A 480 VAC 2HP three-phase motor only draws about 6 amps.
HOW and Why there is 440v supply in three phase and 230v supply in single phase?
because all over the world there is an standard rate of voltage
How many amps is 2 hp at 230V 3 phase?
6,25AnswerWithout knowing the efficiency of the motor, it's impossible to tell. The horsepower rating of a motor describes its output power; you need to know its input power in order to calculate its current.
Why is mains voltage 230V?
Yes 230 volts is classed as single phase but it is not the only single phase voltage. If you take any two legs from a three phase system, the voltage from these legs is also classed as single phase. The 230 volt single phase is the output of a transformer whose primary is one leg of a three phase primary high voltage system. The 230 volt secondary is center tapped to give 115 volts before the tap and 115 volts after the tap, hence the common voltage of 115/230 that is used in North America.
Can you hook up 208 volts on a 230 volt motor?
Yes, a 230 volt electric motor can run on 208 volts. The horsepower will be lowered by .9 or to 90% of the nameplate rating. e.g. A 230 volt 10 HP motor will only produce 9 HP at 208 volts. Note: If motor sees a load equal to its' rated HP it will over amp and shorten the live of the motor and/or trip out on internal overload.
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.
How many amps will a 3 hp motor pull on 230 volts?
It depends on the voltage of the motor, and whether it is single-phase or 3-phase. A 120 VAC 2HP single phase motor draws almost 20 amps, a 240 VAC single-phase 2HP motor draws about 10 amps. A 480 VAC 2HP three-phase motor only draws about 6 amps.
What is the type of motor used in running a lathe spindle?
230V/1Ph/50Hz 1HP (0.75 kW)Motor Capacitor start induction motor ( single phase)

Can you convert 415v 3 phase to 230v single phase?
415V 3 phase is the line to line voltage. The line to neutral of this supply is 230V single phase. Therefore you use one of the phases and the neutral.
What is the Single phase voltage in India?
The single phase voltage in India is 230v when we check with the phase and the nutral single line
What is 3 phase voltage in Germany?
Three-phase voltage in Germany is 400V, single-phase voltage is 230V.
You have 230v 3 phase power can you plug a 230v single phase motor into it?
Any two legs of a three phase system are classed as single phase. So yes a single phase motor will operate when connected. Be sure to use the proper motor protection devices to control the motor.
Can a 230 460 volt 3 phase motor be connected to a 277 480 volt 3 phase circuit?
Yes, that's possible, but only for low-powered motor. You know that in order to start, the stator must be supplied with voltages that are shows shift phase between them, so the trick is to use a capacitor (since it shifts phase current) to simulate a 3-phase source. As indicated in the following picture: http://freecircuitdiagram.com/wp-content/uploads/2010/10/Enabling-3-Phase-Motor-Operates-with-Single-Phase-Supply.gif
What voltage you get at home in India?
The single phase voltage in India is 230v when we check with the phase and the nutral single line
HOW and Why there is 440v supply in three phase and 230v supply in single phase?
because all over the world there is an standard rate of voltage
The motor states 120v single phase to operate.can you use it using 230v supply in Singapore?
Absolutely not. In the U.S. all power is 120v on a single line (one hot, one neutral, one ground) overseas all power is 230v on a single line. Will fry your unit. You can however by a step down or up transformer fairly cheaply at radio shack.
