LIFE SAFETY WARNING! [disclaimer] Electricity is dangerous! You can be injured or killed! Improper installations can cause fire, injury and death! The H1 and H4 are the primary connection terminals on a transformer and the X1 and X4 are the secondary connection terminals. This transformer is a dual voltage primary and a dual voltage secondary. Full terminals will be H1,H3,H2,H4 and X1,X3,X2,X4. Jumpers between H3 and H2 for high voltage primary, jumpers between X3 and X2 for high voltage secondary. For low voltage primary, jumpers across H1 and H3 and H2 and H4. For low voltage secondary, jumpers across X1 and X3 and X2 and X4. See related links for connections. National Electrical Code definition, NFPA 70 2005 Article 100 I: Qualified Person. "One who has skills and knowledge related to the construction and operation of the electrical equipment and installations and has received safety training on the hazards involved." <><><> This is not an amateur level project. Call a professional electrician. <><><>
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.

The Kansas barbed wire museum has over 2000 different types of barbed wire on display and barbed wire collecting is a popular hobby.
who invented electric wire
Barbed Wire Soul was created in 1997.
Bouquet of Barbed Wire was created in 1976.
Yes, first find out how many volts you need on the output. For example, I'll go with 240V for a step up transformer. You would want to put some 10-14 guage wire on the secondary of the transformer, at around 240-250 turns on the transformer. If you can fit thicker wire, then it'll handle more current, but it may blow a fuse once you get such a big transformer.
That could only happen if the neutral wire (white) becomes disconnected at either the panel, the meter base or the transformer.
The wire size you are looking for is #1 copper with an insulation factor of 90 degrees C. This wire is rated at 140 amp but with a voltage drop correction it will give you 100 amps at the load. The wire for transformer feeders at 125% is included in the sizing.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-energizedIF YOU ARE NOT REALLY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
In North America it takes two "hot" wires to obtain 240 volts.
Shield is ground. White is Neutral, center tap of the transformer from the power company.
Yes, it is called back-feeding and should only be done by a qualified electrician who has actual experience with this type of installation. Look up buck and boost transformer connections.
Don't!
K is the ratio of the number of secondary winding turns of wire around the transformer core verses the number of turns on the primary.
why does have to short-circuit secondary wire of current transformer ?
If the 240V 3-phase service is 240V phase-to-phase, then you can get 240V single-phase by simply picking two phases (poles, as used in the question) and connecting the load across them. This is simply one third of a standard delta connection. If you need 120V/240V split phase, i.e. with a neutral, as used in residential services, you will need a transformer. If the service is actually a four wire "quadraplex" service, however, you will probably already have that 120V/240V with neutral connection phase available. In this case, you will need to pick the two phases correctly in order to get the proper 120V service half.
In a transformer it is known as the transformer core.
you could possibly design a fix for it but it would be a lot of trouble. the American dryer has internal components that run off 110v and that 110v is available from the three wire 220v circuit in the typical usa residence. this is because of the third wire, the neutral. the Korean 220 would be 2 wire. you would have to go inside the dryer, add a 220/110 transformer and rewire the dryer so that the 110v loads come off that transformer. it would then no longer be ul listed and would have to be evaluated by the authority having jurisdiction in Korea and back here in the usa.
