How do you wire a Bridgeport Mill running on 440 3ph to 240 3ph?
Dheaysman
Hi there are a few options. The one I chose was to use a VFD (variable frequency drive). First though if you want to run off true lower voltage you will need to check that the motors can be reconfigured to run as delta instead of star. If you look at the motor plate this should give you some idea. If you are lucky the motor terminals will have links that let you move them to reconfigure. If not you will have to research further on the net. If you use a vfd instead of a rotary or static inverter then you will have to connect the output of this directly to the motor ie with no switches in between. All the control like forward, reverse etc are them controlled as low voltage inputs to the inverter. With a rotary or static inverter it is possible to feed the output of these inverters to the supply of the existing wiring but motor voltages and contractors may not work on the reduced supply.

How much current at 240 volts passes through a wire with a resistance of 100 ohms?
current = voltage/resistanceAssuming the 240 volts is across the 100 ohm wire, 2.4 amperespower = current * voltageResulting in the wire dissipating 576 watts... One hot wire!
What wire do you use for 240 V 50 Hz?
You need to mention the current or connected load to define the size of the wire
Wiring a single phase 208 230V compressor to residential 240 using existing 6 3 wire B W R and a ground but compressor only has a two wire and ground requirement?
A 208/230 volt single phase motor only has two wires out. It sounds like you are trying to pick up a feed from a 120/240 source that needed a neutral wire to operate. The black and red wire will give you the voltage you need. Make sure that you use a starter and overload protection for the motor.See discuss question below.
Is there a voltage carrying limit of wire?
Yes it depends on many variables such as what the wire is made of the size of the wire whether the wire is a multi strand wire. What governs the amount of voltage a wire can carry is the insulation that is wrapped around the wire. Like wire with ratings of 300 volts, 600 volts and 1000 volts these are the highest allowable voltages that can be applied. A wire that is rated for 300 volts is good for 120 volts, 240 volts and 277 volts. At test research facilities, insulation is tested to destruction. The label that is given to the wire insulation as a result of the tests is the highest safest voltages that can be applied to that particular type.
How can you connect a 120 volt motor to run with 240 volt?
Answer for USA, Canada and countries running a 60 Hz supply service.Use one leg of the 240v and the neutral wire. Most electric dryers run the motor this way. The heating element is 240v but the motor is 120v.NO, THAT IS DANGEROUS ADVICE because a 240 volt service has a circuit breaker which is sized for the current draw of a large 240 volt appliance, so it would have a rated amperage that is too high to protect a 120 volt motor running on its own.Only 240 volt appliances such as dryers, air conditioners, etc. are safe to use on 240 volt circuits.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.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
Does 240 volt have a neutral wire?
Yes <<>> In North America, a three wire 120/240 volt system uses a neutral wire. For 240 volts two "hot" wires are used with no neutral.
What size wire for neutral in a 240v 30 amp circuit?
Answer for USA, Canada and countries running a 60 Hz supply service.240 volt two wire circuits loads do not need a neutral to operate. A three wire 240 volt circuit that needs a neutral, will have a neutral the same size as the current carrying conductors. In this case a #10.
Is a 220 volt electrical power wire the same as a 240 volt electrical power wire?
Yes 220 & 240 are considered the same.
How do you connect a 3 wire 120 outlet to a 4 wire 240 outlet?
You don't.
Why use 3 wire 240 volt receptacle instead of a 4 wire 240 volt receptacle?
Use the 4 wire if possible. You would only use a 3 wire for an old appliance.You shouldn't if possible. The 3 wire has no neutral wire as the 4 wire does. Som applications require the use of a 3 wire and some don't.

What size copper wire should you use for 240 volts 200 amps?
3/0 wire 3/0 wire
How many volts does 12-2 wire carry?
240
Can you use 600 volt wire for 240 volt appliance?
It depends on the voltage, but if you are using it on a 240 v system, it's quite OK to use wire that can take 600 v (if you had to buy the wire, you would be spending too much).
What is the running coolant temperature?
Anything below 240.
How do you change a 220 240 volt wire to a 110 120 volt wire?
Wire is wire - is doesn't matter what voltage you use. However, if you are changing the voltage on a device from 240 to 120, given the same power requirement, you may need bigger wires for the doubled current (and increased heat of resistivity).
Will 2.5mm wire conduct 240 volts?
You size wire by the current. Various insulations are rated for voltage, temperature and the medium where the wire will be run.
