The motor states it is 230V single phase to operate. Does that mean you need two 120V lines in and just a ground with no neutral?

Answer for USA, Canada and countries running a 60 Hz power supply service. The proper terminology is L1,L2,N. N is for neutral and it is this wire that is grounded. The voltage measurement from the L1 to N will give you 120 volts. Also from L2 to N will give you 120 volts and from L1 to L2 will give you 240 volts. Single pole breakers in the panel board starting at the top, alternate between L1 and L2 all the way down to the bottom. These breakers all have 120 volt outputs. If you plug a 2 pole breaker into two slots then you get a 240 volt output because L1 and L2 are adjacent to one another. <><><> If the rating plate on this motor says 230V and it has a brown wire (the 230V "hot" or live"), a blue wire (the "neutral") and a yellow/green wire (the "earth" or "ground") it was designed for use in Europe or other world areas which use a 50Hz supply. Those wires mean it requires just one "hot", running at 230V and a neutral. In 50Hz areas that neutral is connected to earth (ground) back at the breaker panel. If you are planning to use it in a 60Hz area, such as US or Canada, it would be wise to determine exactly how the ground wire is wired inside the motor. Check it by using a test meter: if it was made in the past 30 years or so the earth/ground wire should be connected only to the frame of the motor and should not be connected to the neutral wire in any way. If you are sure that is the case, then you can use the motor but only if you do not use the 60Hz supply's neutral, which is the white wire. Connect the motor's brown wire to one of the 60Hz supply's "hots" - say the red. Then connect its blue wire to the 60Hz supply's other "hot" - say the black. (It doesn't actually matter which hot goes to which.) Be sure to connect its ground wire to the 60Hz supply's ground, which is green or bare wire, and do not connect the 60Hz supply's white neutral at all. Just leave it blanked off inside an insulated connector or wire nut.
If it is an old type of 50Hz motor it might have a red (or, in newer models a brown) 230V hot wire with a black (or, in newer models a blue) neutral wire with plain green (or yellow/green) ground wire. If, using a meter, you find the motor's ground wire is linked both to the frame of the motor and to its neutral wire, that link to the neutral will have to be cut before you try to use the motor. Leave the ground wire connected only to the motor's frame. If you don't make sure that link is cut so that the neutral is no longer connected to the ground wire, you will have big problems when you hook up the motor because, back at the breaker panel, the 60Hz supply's neutral is connected to the ground, so if that link within the motor had not been removed, it would cause a short to whichever 60Hz hot (red or black) you connected to the motor's neutral wire! Note: if the motor does not have brushes running on an armature then it is a squirrel cage or similar type induction motor, which means that, running on 60Hz, it will spin at a speed 60/50 of its rated design running speed. That is 20% faster than it would spin at 50Hz, so it would be wise to check that the higher speed is suitable for the equipment you want to use the motor for.

on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

Do you have to be 18 to operate a baler?
Most states require you be 18 to operate a baler. Some states require that you are only 16.
Do you use ground as neutral?
Answer for USA, Canada and countries running a 60 Hz power supply service.Once upon a time, this was legal and routinely done, especially on electric dryers. It is no longer legal anywhere that I know of. If your equipment is grounded using a separate ground wire, and the neutral wire breaks, the appliance may not function, but no one will be hurt.If, on the other hand, you use the ground wire as the neutral, and it breaks, IF THE APPLIANCE HAS A METAL CHASSIS AND/OR CASING CONNECTED TO THE GROUND WIRE IT WILL BECOME LIVE!Anyone touching it could be killed!It's just not worth saving a few dollars over. Buy and install the proper 4-conductor cable (called 3-wire with ground) and be safe.A different take from a professional appliance installer and electrician:Up until the mid to late 1980's the ground and neutral were tied to the same bar in the panel. So unless someone who has a house built prior to this has had a complete electrical service rebuild the ground and neutral of all of the circuits are connected to the same place.If you have an older home and there are only three wires feeding a 220v appliance the ground and neutral are interchangable. In fact, if the unit had two hots, a neutral and a ground, the ground and neutral were tied together. This is still acceptable practice and is diagrammed in the specifications for every appliance appliance that I am aware of. (Only Miele for a time was particular about not mixing the ground and neutral, although they could never tell me why it mattered. They have since dropped that requirement).There are a lot of new 220v appliances that have only three wires. Usually two hots and a ground. It would be perfectly fine to hook the ground to the neutral if that was all you had.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.
Why doesn't current flow through the neutral to earth?
The 'hot' wire delivers current from the power station into the load, which could be any electrical appliance such as, for example, a fridge, a light or a motor.The 'neutral' wire is there for the specific purpose of carrying the current coming out of the load back to the power station. If the neutral wire was not there, there would not be a complete electrical circuit from the source (power station) to the load and back to the source.In normal operating conditions the connection from the neutral wire to the Earth does not carry any current.There should always be 0 V (zero volts) between the neutral wire and the Earth. i.e. no potential difference should ever exist between the neutral wire and the Earth.The "neutral to earth" connecting wire is fitted to ensure that no part the neutral side of the circuit can develop a high voltage above Earth. If that connecting wire wasn't in place and the circuit had no other protection device (such as a GFCI or RCD) fitted, a very dangerous electrical shock hazard could be present which could electrocute the people using the appliance.That is why any grounding wires, fitted either to the appliance or to the breaker box, should never ever be cut or removed.
What is 208 - 230 volt three phase?
In the United States, 208v can be either. It is generally the voltage supplied by a 120/208v 3 phase system. However, using 2 legs of this 3 phase system is called single phase. I won't go into the reasons for that but just understand that 208v can be either single phase or 3 phase.
A complete electric circuit includes a voltage source current wires and something to ground the flow of current?
If you ground the flow of current like the last part of your question states you will not have a complete circuit as the circuit will open on a short circuit. To make a complete circuit operate you need a power source, an overload device to protect the conductors of the circuit, conductors to carry the current and a load across the power source which causes the current to flow in the circuit. Leave any one of these things out and you will not have a complete circuit.

Can neutral and ground wires be connected to the same buss bar in a service panel?
No. The sub panel is wired that same as an ordinary three wire load. The three wire is connected the sub panels terminal points as red to L1, black to L2, white to the neutral bar and the ground wire in the cable set to the ground bar. The one thing that has to be done is the bonding screw that bonds the neutral bus to the panels metallic enclosure has to be removed. The electrical code states that there is only one place that the ground is joined to the neutral bar and that is at the service entrance point into the main distribution panel.
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.
