ONLY if you can run a single wire along side the 2-wires. If not, running a 3rd by itself will cause the magnetic field of the wire to overheat (when they're run together, the magnetic fields cancel each other out).
Short answer: Probably not.
You cannot run a separte wire all by itself if the 8-2 is in a cable assembly. It isn't allowed by code. Technically you could run 8-2 cable, and then a separate #8 within a conduit, overheating will not occur and the wires do not cancell each other out when considering magnetic fields. It is however true that Phase A and Phase B have completely opposite magnetic fields, but overheating still occurs, this is why wires are derated when they are all run in the same conduit.
It is more accurate, a 4 wire is more accurate than 3 wire and 3 wire is more accurate than 2 wire.
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.
put a resistance in one of the wire connecting.....put around 2 to 3 ohm resistance to obtain 3 v fron 6 v.....
any 2 of the 3 wires
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.
10 is the gauge of the wire, 2 and 3 are how many leads are in the wire. For instance 10-2 wire is 10 gauge with two leads, 10-3 is 10 gauge with three leads.
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.
Answer for USA, Canada and countries running a 60 Hz power supply service. Yes, but you will need to change the wire from a 2 wire cable to a 3 wire cable. This allows the neutral to be brought out to the load.
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.
30 amp duplex breaker...and you should use 10/3 wire, not 10/2. 10/2 is for water heaters.
2 wire.3 wire nd 4 wire...rtd... 3 wire rtd is widly used....hv good accuracy...
