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.

How do you add a 240 volt receptacle to 100 amp supply?
The 240 volt receptacle has to have an amperage rating. It is this rating that governs the wire size and breaker size to feed the circuit. The new two pole breaker will be inserted in the 100 amp distribution if space is available and connected to the new wiring that terminates at the new receptacle.
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 is the position of the ground pin on wall receptacle?
In North America on a 120/240 volt home electrical system, the ground pin on a duplex wall receptacle is on the bottom.
When is white wire hot?
In residential wiring, if it is used as a switch leg or in 3 wire 240 volt circuits.
Is red or white neutral for electrical work?
In residential wiring the white wire is neutral on the 120 volt circuits. On a 3way circuit the red is the traveler and the white is neutral. On a 240 volt 3 wire connection the white & black are hot. On a 240 volt 4 wire connection the black and red are hot and the white is neutral.
If a receptical outlet doesn't have neutral wire where is my problem?
The receptacle that you are looking at might be a 240 volt receptacle and that is the reason, there is no neutral needed. You should be able to tell by the configuration of the blade pattern if it is rated for 240 volt operation.
Can you put a 120 v receptacle on a 240 v circuit breaker?
No, the electrical insulation rating of a 15 amp duplex receptacle is only rated at 130 volts. The 15 amp 240 volt receptacle is rated at 250 volts. The 240 volt receptacle also has a tandem pin configuration instead of the parallel configuration of the 120 volt device. The different pin configuration is so that a 120 volt electrical device can not be plugged into a 240 voltage receptacle.
Can you install a 277 volt receptacle in place of a 240 volt receptacle?
No. To prevent this sort of thing from happening, the 277 volt device and receptacle is physically larger that a 240 volt receptacle and will not fit in a regular receptacle junction box. For a 277 volt system the proper size junction boxes have to be purchased.

Can a 240 volt receptacle go on a 15 amp circut breaker?
In North America you would need two 15 amp breakers to obtain 240 volts. The wire for a 15 amp circuit would be #14 AWG. So to answer the question, yes a 240 volt receptacle can go on a 15 amp circuit.
Can you install a receptacle that is rated for 240 volts to a 277 volt line?
No, the receptacle's rating is 240 volt and that is the maximum voltage allow to be applied to that device. To prevent this condition from happening 277 volt receptacles and switches have a larger box that they fit into. The retaining screws are set apart further that a 240 volt device which makes it impossible to install a 240 volt device in a 277 volt junction box.
Is a 220 volt electrical power wire the same as a 240 volt electrical power wire?
Yes 220 & 240 are considered the same.
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.
Can you wire a 240 volt window ac from a 277 volt feed?
no
Can you plug a 240 volt appliance into a 110 volt system?
The pin configuration of the 240 volt receptacle is different from a 120 volt pin configuration. This is a safety factor to prevent the wrong voltage being applied to the wrong devices.
