The transformer should have identification on it. The H1 and H2 terminals are for the primary side of the transformer that connect to the supply voltage. The secondary terminals will be identified as X1 and X2 and these connect to supply the load with a voltage that it needs. This identification is regardless of whether the transformer is a step up or step down type of configuration.
The primary wires would attach to the outlet, while the secondary wires would attach to your device. If there are 3 secondary wires, that means they are center tapped, most likely at half voltage, and when you use the wire that's a different color from the rest with either of the other wires, you'd have 6 volt or whatever.
It is common practice in DC appliances that attach to the outlet to use two half-wave rectifier circuits to produce full-wave DC at half voltage. So a 6 volt clock radio may contain a 12-volt, center-tapped transformer, and a large stereo might contain a 24-volt, center-tapped transformer.

Why live and neutral wire essential for proper working of electrical circuit?
Two wires are always needed to supply electrical equipment so that the current has a complete circuit to flow in. One of the wires is earthed at the supply transformer, that one is called the neutral, and the other one is the live.
Connecting a 240v to 24v 40va transformer?
To connect a 240V to 24V 40VA transformer, you will typically have two input wires for the 240V side and two output wires for the 24V side. The 240V input wires will connect to your power source, while the 24V output wires will connect to the device or circuit that requires the lower voltage. Make sure to follow proper wiring guidelines and safety precautions to avoid any electrical hazards.
What will happen if you get the main power from two live wires instead of a live wire and a neutral wire?
If you connect the main power from two live wires instead of a live wire and a neutral wire, it can lead to a short circuit in the electrical system. This can cause damage to your appliances, risk of electric shock, and could potentially start a fire. It is important to always connect electrical wires properly to ensure safety.
Panel box with a 3 pole 4 wire 440 volts 3 phase electric and you need to pull 220 volt single phase with 2 pole 3 wires how do you do it?
You can install a 220V single-phase transformer to step down the 440V three-phase supply to a 220V single-phase output. Connect the transformer's primary winding to the 440V three-phase source using the three poles and four wires. Then, connect the secondary winding to your 220V single-phase load using the two poles and three wires. Make sure to follow local electrical codes and regulations when performing this setup.
How do you connect 4 wire timer model tmdf702zh2?
To connect a 4-wire timer model TMD-F702ZH2, first identify the wires: typically, two for the power supply (live and neutral) and two for the load (common and normally open or normally closed). Connect the live wire to the timer's live terminal and the neutral wire to the neutral terminal. Then, connect the load wires to the appropriate terminals based on your desired operation (NO or NC). Finally, ensure all connections are secure and power on the timer to test its functionality.
Why neutral is earthed always?
The two wires carrying a standard ac power supply are the live and the neutral. By convention one of the two wires is earthed at the transformer providing the supply. That then becomes the neutral and the other wire is the live.
If a centre tap transformer rated as 12V-0-12V 1Athen what will be the secondary current of that perticular transformer?
The output voltage of a transformer is not connected to the maximum rated current. You state that the transformer is rated at 12-0-12 at a current of 1A, therefore the maximum (rated) current on the secondary would be 1A. Normally, transformers are rated in VA (volt amps) which is simply voltage x current, the voltage across the two 12v terminals would be 12+12 volts, making the rating of the transformer 24VA.
Why live and neutral wire essential for proper working of electrical circuit?
Two wires are always needed to supply electrical equipment so that the current has a complete circuit to flow in. One of the wires is earthed at the supply transformer, that one is called the neutral, and the other one is the live.
How do you install 12V power outlet in ford winstar?
drill hole in dashboard, install outlet in hole, and run two wires to the battery
Why in center tapped transformer tap ground is used?
It is normal to ground the centre tap of a centre-tapped winding so that the live voltage on either end of the winding is minimised relative to earth. In North America the 240 v secondary of a supply transformer has a grounded centre tap so that a property can be supplied with two separate 120 v circuits for lighting and other low-power use, while a 240 v supply can be taken from the two live wires for high-power use for cookers, aircon etc. In Europe split-phase supplies are used in rural areas where a 460 v transformer-secondary is centre tapped and a 3-wire supply sent to a remote site with a neutral wire and two 230 v live wires. Alternate properties are connected to alternate live wires and if they all use the same current there is no current in the neutral wire going back to the transformer, and therefore no power is lost in the neutral wire.
Did in philippines have a 2 phase electricity line supply as of now specially in residential houses...?
Two-phase systems have not been in general use for about 100 years because they were replaced by three-phase systems worldwide. Another type of power that is still used is 'split-phase' which is a single-phase supply using a centre-tapped transformer. For example a supply transformer has a 240 v secondary with a grounded centre-tap, so that two separate 120 v live wires are connected to the property, along with the neutral. High-power appliances like cookers or aircon can be connected across the two live wires to work at 240 v. Split-phase is also used in Europe with a 460 v centre tapped transformer used to supply a relatively small remote community, with individual properties fed a 230 v supply from one or other of the two live wires plus the neutral. The advantage is that it reduces the current in the neutral wire, and if both live wires happen to supply equal currents the neutral current going back to the transformer is zero, thus reducing power lost in the wire.
Connecting a 240v to 24v 40va transformer?

Which of the four wires for the front speakers of a 1989 Chrysler Le Baron are hot?
I'm assuming you're referring to the 4-way Infinity connector. The center two wires (green and black on the speaker sitting on my shelf) are the + and - for the audio, repsectively, and the red and grey (outer two wires) are +12V and ground for the onboard amp in the Infinity speakers.
What happen when two live wires touch each other?
Sparks
How a simple transformer can be made?
The absolute simplest transformer would be two pieces of wire laid next to each other. Changing current in one wire would induce a magnetic field that in turn induced a current in the other wire. This would not be efficient though. Coiling the wires concentrically would increase their interaction and efficiency, but for a functional, simple transformer, wrapping the wires around a soft ferromagnetic materiel with a high magnetic permeability and high field saturation makes for a much more efficient transformer.
What is the difference between ordinary transformer an center tapped transformer?
An ordinary transformer has two input/output terminals but a center tapped transformer has 2 input and 3 output terminals. One is taken from the center for a ground connection. This causes it to get 50% of the actual value. And ordinary transformer contains 2 windings. An autotransformer has one.
