Canada and US - Visualize it the other way around. The transformer that feeds your house has a primary of 7200 volts. The secondary voltage is 240 volts. This secondary voltage is a split voltage. There are 3 bushings coming out of the transformer on the secondary side. The two outside bushings have the 240 volts on them. The position of the center bushing splits the 240 in to two 120 volts. This center tap is then grounded and becomes the neutral of your house wiring service. L1 to N = 120 volts, N to L2 = 120 volts, and L1 to L2 = 240 volts.

When two 120 volt lines from the power grid are joined together, they are 180 degrees out of phase with each other. This means that when one line is at its peak voltage, the other is at its minimum voltage. By combining these two lines, the potential difference between them adds up to 240 volts, resulting in a 240 volt supply.

∙ 11y agoDo you mean tying two breakers together or tying two 120v wire together. You can tie two breakers together with a breaker tie bar if they are each on seperate legs of the panel and yes you will then have 240. If you are talking about tying 2 120v WIRES together BE CAREFUL! If those two wires come from different 120v legs of the panel you will have a direct short and a pretty serious spark to put it mildly. You should only tie 2 120v wires together that are on the same circuit. And you'll still have 120 at that point

What is made of two or more cells together in electricity?
A battery is made of two or more cells joined together in electricity. Each cell contains chemicals that react to generate electricity. When cells are connected in a battery, their combined electrical potential can be used to power devices.
What holds up power lines?
Power lines are held up by tall metal structures called transmission towers or poles. These structures are designed to support the weight of the power lines and withstand environmental factors like wind and weather. The power lines are typically attached to insulators on the towers to prevent electricity from traveling down the structure.
Why is flying a kite near a pylon dangerous?
Flying a kite near a pylon is dangerous because the kite string can conduct electricity from the power lines, leading to electric shock or injury. Additionally, the kite may get entangled in the power lines, causing damage to the lines and potential power outages. It's best to fly kites in open, clear areas away from any overhead power lines.
How much snow does it take to cause a power outage?
It can vary, but generally when snow accumulates over power lines in significant amounts, it can cause power outages. Wet, heavy snow can weigh down power lines and tree branches, leading to equipment failure and disruptions in power supply.
Why do blizzard's lose power?
Blizzards lose power because some power lines freeze and other get knocked over with harsh winds.
What are those orange balls that are on some power lines?
In some areas they are for preventing the power lines from hitting together and starting a fire. They also increase the visibility of the lines to helicopters etc.
Why was the Montgomery bus boycott a tremendous victory for African American?
The Boycott proved the power they has if they joined together
How crow does not get electrocuted when it sit on the electric power lines?
Birds perching on power lines do not get electrocuted because they are not completing a circuit by touching another conductor. The power lines are insulated and the birds' legs are not close enough together to create a path for electricity to flow through their bodies.
What were the major causes of the victory of the Medes and the Persians?
The two peoples joined together under Cyrus, and so had the power to overcome their neighbours.
What leader left the axis power and joined the allied powers?
Italy joined the Allies during WWI, but no Axis Power joined the Allies during WWII.
Are there power lines in heaven?
there are no power lines in heaven
Why has electricity become unstable?
Electricity became unstable when there is a defect on its power lines, or there is an interruption and less production from its source.
Why did Adolf Hitler become a soldier?
He believed in Germany, he believed that it could be a world super power, this is why he joined the German army even though he was not a German himself.

Can California and Nevada be joined and become a state?
California and Nevada could be joined and become a state. Yes it is possible. Will it happen? No. Both now have two senators. If they joined they would lose two senators. They would lose power. That will not happen. California is now broke. If Nevada joined California the people of Nevada would need to help pay debts they had no part in creating. A number of California retirees receive much larger pensions than their equivalents in Nevada. The people of Nevada would not want to pay them.
Why is a power line more likely to break in winter than in Summer even if it is loaded with the same weight?
In winter, power lines can become more brittle due to colder temperatures, making them more susceptible to breaking under the same weight load. Additionally, winter conditions like ice and snow accumulation can add extra weight to the power line, increasing the risk of breakage.
Can birds touch one another when there on power lines?
The answer is yes they can touch one another when there on power lines
