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 run a 110v heater on 220v circuit?
No.It'll overload and fail just about immediately.It's possible - but not recommended - to run two 110 v heaters in series from a 220v circuit.
What are the two most popular operating voltages for residences?
120v and 240v
What happens when you connect a 110 volt motor to 220 volts?
On a three wire supply system if you connect the two 110V wires together and they are across the phase they will short out and trip the breaker. If the two 110V wires are supplied from across the phase and connected to a motor then the motor will run. If the 110V wires are on the same phase nothing will happen.
How do you wire a 240V 60Hz 20A convection oven?
two hot one ground
IS there an adapter for a 240V heater that will allow you to plug it into two 110V outlets?
No. Sounds like a fairly hazardous thing to try as well. If it's to use a heater in the US, then buy a US heater at a lower cost than any adaptor that might do the job for you. If it's to use on a UK building site that has 110V but doesn't have 240V, it breaks all the rules because you end up with 240V where you shouldn't.
Single phase 4 pole Gen alt w 240V 60hz output no neutral. you check from each lead to ground and get 50-70V How do you get a neutral for connecting Gen to a standard breaker box having 240V and 120V?
If the generator does not have a neutral wire, one option is to create a artificial neutral by bonding one of the hot wires to ground. This should only be done if the generator is designed for this application and in line with local electrical codes. It is recommended to consult with a qualified electrician to ensure this is done safely and in compliance with regulations.
What adapters do you need to plug your 240V Ac plug into a 110V AC supply?
You would need a step-up transformer or voltage converter to plug a device with a 240V AC plug into a 110V AC supply. Make sure the converter can handle the wattage of your device and has the correct plug type for your country.
Do you need a neutral when running a BLK Red and ground from a panel directly to a 240V 4800W 20A heater outlet?
Yes, you don't need a neutral wire for a 240V circuit, but you do need to connect the black (hot) and red (hot) wires to the appropriate terminals on the 240V outlet. Make sure to ground the outlet properly for safety.
How is the power supply in Europe delivered with two wires and still 220 volts?
Oh yes. They do provide 2-wire 220V and even 2-Wire 240V service in Europe. We went a different way in the States early on when we attached a center-tap wire in those same service transformers to provide 2 x 110V services, along with one 220V service. It is worthy to mention that 110V (220V) services in the US progressed to 115 (230V) and now stand at 120V (240V).
If you have a 240V dryer and installed 30A breakers on both sides of the line reads 120 and 120 how do you get 240 and you have a receptacle that reads 30A 125250 and still does not work?
you do NOT put two 110v breakers in. you put 1 two pole breaker in. the panel is designed to give you 220v off one side OR the other side if you use a 2 pole breaker on one side or the other side. If you look at both 120V lines on an oscilloscope you will notice that they are both 120V to the neutral, but they are 180 degrees out of phase. This means that when one hot is at +120V the other is at -120V. So between the two you have 240V. If you put your meter across both hots you should see 240V. If you do not see 240V across both hots you (or an unlicenced electrician) has wired the outlet without using a proper 220V breaker. You do not see 240V because the hots are in phase, to the voltage differential is 0V, not 240V. 220V breakers cannot do this, unless forcebly installed in the wrong type panel. More than likely someone tried to wire it with 110V breakers.
How do you wire 240V straight blade outlet when both screws are brass?
Both screws are brass because in the US you need two hots to get 220V. In a 220V only circuit you do not connect the neutral, only two hots and a ground. This is why 220V breakers are twice as wide as 110V and have two terminals instead of one.
What two items are needed to make a generator?
A wire and a magnet
In the event of a city power cut can you use a single-phase 240V generator to connect across the two 120V phases supplying the house and would you still get 120V to neutral on each side?
AnswerYes you can BUT because you asked this question you should have a pro show you how to do it. Just to give you a worst case example, transformers work in both directions so if you feed the "city" with 220v your neighbors will enjoy your power until your generator burns up. Maybe 2-3 seconds! Another thoughtYes, IF you have a neutral connection at your generator. If you do not connect the neutral you will not have 110v from hot to neutral. This is because your house must be perfectly balanced across the neutral to have the correct voltage divider to split 220V into 110V. This is near impossible in a residential situation. You need the neutral for 110V. Also, buy a generator transfer panel if you plan to power your house off a generator. It's the law.MoreNot because it's the law, but if you don't have a transfer panel and you connect it directly to your panel you'll also be putting current to the lines coming into your house. This is real scary for the electricians that come out to repair the power. The (city) power is off and they don't expect to see (feel!) any on your end. You could end up electrocuting someone.
What causes a 220v wire to pull only 110v?
A common reason for a 220V wire to only have 110V is that the circuit is wired in a split-phase configuration, where each conductor is carrying 110V with respect to a neutral wire. This configuration is typical in residential electrical systems where 220V appliances use two 110V legs. It's important to ensure proper wiring and connections to avoid safety hazards or damage to electrical devices.
Can you plug two appliances a 120v and a 110v on the same line which is a 110v?
Should be ok provided you do not draw too much current.
Is it feasible to change two 240v 10 amp outlets on your 5.5 kva generator to two 15amp outlets?
Since it's your generator, you can do as you please; HOWEVER...you should understand that the 10 amp breakers that were installed when you received the generator are there to protect the generator from damage. The larger capacity breakers could result in damage to the generator.Two 15 amp circuits at 240 volts can pull up to 7.2 KVA from a 5.5 KVA generator... which will destroy it.Probably not. So long as you do not draw more than 5.5 kva at any one time, or 22.9 amps at 240v, the actual generator, that is, the part of your equipment that actually produces electricity, can handle about anything. But your generator is probably wired such that it cannot safely provide 15 amps to any one outlet.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.
