If you are referring to a.c. three-phase systems, then a three-wire system is associated with a delta-connected system, while a four-wire system is associated with a star, or wye, system. The conductors being three line conductors and a neutral conductor.

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 are the different RTD types?
2 wire.3 wire nd 4 wire...rtd... 3 wire rtd is widly used....hv good accuracy...
How do you Calculate MF in 3-Ph 4 wire energy meter?
how to calculate m.f. of energy meter 3 phase 4 wire h.t. & l.t.
How do you write abbreviation for 3-phase 4-wire?
It is written 3 ph 4 w.
What cable size of wire if the machine is 50hp?
If it is a 480v 3 pH machine, #4 wire will be fine.
Explain the comparison between dc 2 wire system and ac single phase 2 wire system and ac 3 phase 3 wire system and ac 3 phase 4 wire system?
of all of dem 3 phase 3 wire is most economical as it uses less conductor dan in 4 wire system, 3 phase 3 wire is used in transmission and 4 wire in distribution as it has 3 live and one neutral wire. 3 phase needs lesser conductor size than 2 phase 4 wire for the same power. 3 wire dc feeder is more economical than 2 wire dc feeder for the same power. that was all i cud get..... hope u find it a lil helpful.
Is there a neutral conductor in a 3 phase 4 wire wye system?
no
How do you wire a 220 3 wire breaker to 4 wire dyer?
Buy a 3 wire cord for your dryer.

Can delta connection be used on 3 phase 4 wire system?
A delta connected appliance can be connected to a 3-phase system by leaving the neutral unconnected. The appliance must be properly earthed.
How many oxygen sensors on a 2004 silverado?
It has 4 and there all screwed into the exhaust system/pipes. They are about 3 to 4 inches long with an electric wire going to them.
What is the Advantages of 3 wire rtd over 2 wire rtd?
It is more accurate, a 4 wire is more accurate than 3 wire and 3 wire is more accurate than 2 wire.
What are the procedures for the connection of single and 3 phase circuits?
Single phase connection has 1 phase wire and a neutral wire. Another wire for protective earth. In three phase system, motor can be connected in star or delta. Most AC induction motors are in Delta. Power distribution system is generally 3 phase 4 wire. Transmission system is 3 phase high voltage. Industry uses 3 phase system, where as 1 phase is for domestic, commercial applications. Both 1 and 3 phase system has a frequency. It is either 50 Hz or 60 Hz, depending upon the country or region.
Which connection is best suit for 3 phase 4 wire service and why?
STAR connection is best suit for 3 phase 4 wire seviceas there is a neautral wire is there in this connection
Why is an insulated ground wire used in a 3 phase 4 wire system?
A three-phase 4-wire system has three live wires and a neutral, which is earthed at at least one point at the transformer. All current-carrying wires are insulated in this system, for safety. The voltage on the neutral might be zero or only a volt or two, but under fault conditions its voltage could be much higher.
Is it safe to use an oven that has a dryer plug put on?
It will work if, the dryer plug you are using is the same electrical voltage as the oven. If your oven is electric, it is 220 - 240v, if gas, 110 - 120v. A 220 plug has either 3 or 4 prongs, depending on your appliance being a 3 or 4 wire system. A 4-wire system will have a red wire (110v power), black wire (110v power), white wire (neutral/common), green wire (ground). A 3-wire system will be missing the white or green wire. 110v system (gas oven or dryer) will have a black (power), white (neutral), green (ground). It will work, but be limited. Dryer circuits are 30A, whereas oven circuits are 50A. You cannot just upgrade the dryer wiring to 50A as it is not rated for that and will start a fire. To use the oven properly you need to install a properly rated circuit. Do it right or don't do it at all. Negligence is fatal with electricity.
