Your house must be wired according to the regulations in your country and in most countries that would need 3 wires for each circuit - live and neutral carrying the current plus an earth wire properly connected for safety.
Yes, you can use 10-3 wire instead of 10-2 wire for basic wiring. The extra conductor in the 10-3 wire is typically used for grounding or carrying an additional circuit, providing more flexibility for future electrical needs. Just make sure to properly connect and terminate the wires according to the electrical code requirements.
It is more accurate, a 4 wire is more accurate than 3 wire and 3 wire is more accurate than 2 wire.
To answer this question fully the type of appliance has to be stated and its voltage.
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.
The only way to change a 14-2 wire into a 14-3 wire is to physically remove the 14-2 and replace it with a 14-3.
A 2-pole wire will not work on a 3-pole plug. You will need to use a 3-pole wire on a 3-pole plug.
The main difference between 10-2 and 10-3 wire is the number of conductors they have. 10-2 wire has two conductors, typically used for a hot wire and a neutral wire. 10-3 wire has three conductors, typically used for a hot wire, a neutral wire, and a ground wire.
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.
2 wire pumps have the start controls inside the motor, 3 wire have a separate start panel that needs to be mounted in a dry location above ground. If there is a problem with capacitors or relays, the 3 wire panel can be repaired easily. Not so much with the 2 wire. 2 wire can be cheaper and quicker to install.
2 wire.3 wire nd 4 wire...rtd... 3 wire rtd is widly used....hv good accuracy...
Yes, you can connect a 3-wire fan to a 2-wire supply, but you will lose the functionality of one of the wires. Typically, the third wire on a fan is used for speed control or monitoring purposes. If you connect a 3-wire fan to a 2-wire supply, the fan will run at full speed without the ability to adjust it.
If you have some coils of wire and a house that needs rewiring, an electrician is needed to complete the job. He/she would also know if the wire you have is the correct wire to use in the rewiring.
