Water heaters are wired this way, as are cooktops that don't have ovens. As long as you're working with something that only requires 220, like a water heater or a stick welder, this works well.

The third wire is for things like a range, where the heating elements are 220 and the clock is 110. The neutral wire allows you to power different parts of the range with the voltage they like best.

yes

Another homework question. Sure you can if you KNOW what you have with those 2 wires. There are not any stupid questions, but there are alot of dumb ones. I stopped being spoon-fed when I was about 2 years old. Read the book. Learn, Study, Dealing with electricity can save lives OR Kill...pkazsr

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.


Why is there no neutral on a 240 cooktop?

A 240V cooktop does not have a neutral wire because it operates on a 240V split-phase system, where 240V is supplied by two hot wires, with no need for a neutral wire. The two hot wires provide the necessary power for the cooktop to operate efficiently.


Can you use a 120v cord that will fit a 240v socket the appliance is 240 and the cord is thick?

120v and 240v cords usually have different end configurations and will not plug into the different recepticles. However, if you changed the plug end, and the cord has the proper size rating, then yes, you could use the same cord. But, it also depends on the cord too. Most 120v cords only have three wires in them. One "hot one "neutral" and one "ground" wire. A 240v cord would have FOUR wires, two "hot" wires, one neutral wire, and one ground wire. Therefore, if you changed the voltage from 120v to 240 using a 3 wire cord, you'd not have a ground wire and that could be VERY dangerous. Note that occasionally a 240v device (e.g. some motors) will only need three wires (red,black,green, no neutral) and can be wired with a 120v cord if the cord is rated for 240v.


How do you connect a 240V electric cooktop with four wires to the 120V services from the electric panel which is 2 wires?

If your electrical service is only 120 volts you have a problem. There is no way that you can connect a 240 volt cook top to that service. You have two options, one is to upgrade to a new 120/240 volt electrical service. Your other option is to find a 120 volt electrical cook top.


When connecting a 240V line with two hot wires and a ground does it make a difference if the red or black hot wires are connected to L1 or L2 for a jet pump pressure switch?

No, it does not matter which hot wire (red or black) is connected to L1 or L2 for a jet pump pressure switch in a 240V setup. The important thing is to ensure that each hot wire is connected to one of the two load terminals of the pressure switch. Make sure to also connect the ground wire for safety.

Why are you not getting 240v between the two hot wires?

Because they are "in-phase". In order to get 240v, you need two 120v Alternating Current lines that are 180° out of phase, that is, opposite phases. Only when one line is +120v and the other -120v will you see 240v between the wires.

Can you use one wire from the panel with 240v on it to wire a 240v water heater?

In North America it takes two "hot" wires to obtain 240 volts.


What is 2 wire plus ground 240V?

With one interpretation of this question, the answer would be two 120V wires and a ground.


How many wires do you need if you are stepping up single phase 120-240V to 480volts?

Five wires. Two on the primary side, connected to each 120V leg, giving a primary voltage of 240V. Two on the secondary side, one connected to neutral, and the other the new 480V hot. One connecting the frame of the transformer and the box containing it to ground. Note: you will only get one phase power out of this configuration - to get three phase output, you need three phase input, three transformers, and a lot more wires.

Can you join red and black wires to get 240V?

You should never trust any wiring without using a tester (get one at hardware or home improvement store. ) in USA, White/grey/bare wire is neutral, colored wire is hot (live). In a pure 240v connection, there are two hot wires and no neutral wire. Sometimes they still use black and white for this. If you are seeing black and red wires you might be looking at a split phase panel -- you'd best check that out


How do you properly wire a double pole breaker for 240v?

To properly wire a double pole breaker for 240V, connect the two hot wires to the breaker terminals, the neutral wire to the neutral bus bar, and the ground wire to the ground bus bar in the electrical panel. Make sure to follow the manufacturer's instructions and local electrical codes for safety.


How do you hook up a 3 wire water herter to 4 wire circut?

4 wire household wiring is black, red, (hot wires) white (neutral) and bare or green (ground wire). You say 3 wires. Is it 120v or 240v. If its 240v which is more common just use the two hots and the ground and cap off the neutral wire.
