No. The National Electrical Code does not allow line to neutral loads on a 240 volt line. Besides that the line to the air conditioner will not have a neutral for the 120 volt line anyway. If you cheat and use the equipment ground that is another very dangerous code violation.

Can you take 120V off a 240V circuit?

If I read your question correctly, you want to both have 120V and 240V outlets coming off of the same tandem breaker. The code compliant way to do this is to add a sub-panel at the end of the 240V feed and then have separate breakers feeding the 240V and 120V outlets.

Can you split a 220v line into 2 110v lines?





You can convert a receptacle from 220 volts to 110 volts in one of two ways. The first is to use a 220 to 110 adapter. The other is to rewire the receptacle or install a new receptacle next to the old one and connect it to the 220-volt wiring.

Can an air conditioner share an outlet?

Even if the AC does cause a current drop when it kicks in (like my printer does), it shouldn’t be a problem. The UPS will just kick in for a second. Typical house receptacle is 15 amps.

How do I go from 240V to 120V?

Quote from the video:
Quote from Youtube video: First. There you go 120. Here in the box. Itself grounded good and now between both should give 240.. And there you have it 240 volts if you have a 240 volt circuit that you want to convert to 120.

Can you wire a 120V outlet to 240V?

IF the outlet is the ONLY outlet on the circuit, it’s perfectly fine to change it to a 240V outlet (or disconnect, given it’s for a heat pump) and change the breaker to a two-pole 240V 15A breaker – all your 120V wiring is already rated for 250V if not 600V.

Can I pull 120V outlets from a 220v box with no neutral?





NO! That would be a National Electrical Code violation and a dangerous practice. That would energize the the ground wire and someone could be electrocuted from a wire they can normally expect to be safe.

Can I run 110 outlet off 220V outlet?

You can convert a receptacle from 220 volts to 110 volts in one of two ways. The first is to use a 220 to 110 adapter. The other is to rewire the receptacle or install a new receptacle next to the old one and connect it to the 220-volt wiring.

Can you use half of 220 breaker for 110?

The answer to question one is “Yes”. It’s perfectly possible. Every other 110V circuit in your house is powered by splitting this same three-phase 220V AC into sub-circuits. If you look at your panel, the circuit breakers are arrayed like this (Yay for ASCII art!)

Can you reduce 220V to 110V?

Converting 220 volts to 110 volts is possible. You can convert 220 volts to 110 volts by either using an adapter plug or removing the existing 220 receptacle from the outlet box.

Can I convert 240V to 110V?



240V to 110V Transformers – What do they do? Transformers, when plugged into a standard 240 volt power supply, drop the voltage to a safer 110V so you don’t have to use expensive circuit breakers. They are made up of 2 x 55V lines to form 110V.

Can you combine two 120V to 240V?

With long enough cords, you can combine the two and get 240V, but you will still be limited by the circuit breakers behind them…

Can I plug 120V to 220V?

Do not plug a 120V device directly into a 220V wall socket, even if the plug shape and size are identical. Although goods sold in the U.S. but available around the world sometimes accommodate 220V voltages — iPods, for example — other devices can be destroyed by such high voltages. When in doubt, use a plug adapter.

What happens when you plug a 120V into a 220V outlet?



It is current that is your enemy, a piece wire that is warm at 110V (120v) will turn into a fuse at 220V (230v, 240v), all other things being equal. Determining the wattage/load is usually performed by the design engineer to meet the performance specs set by the electrical engineer.

How do I convert 220V to 120V?

Quote from the video:
Quote from Youtube video: And what we're going to do is is we would turn this breaker off of course there should be no power to the panel. Anyways. Then we're going to remove these two wires right here.

Will a 120V motor run on 240V?

Yes, but it will have a much lower power output, probably maximum of 1/10 hp power delivery. If you try running it directly from 120V, keep an eye on it to make sure it doesn’t overheat. You really should keep the voltage to frequency ratio the same as what it was designed for.

What is advantage of using 240 volts over 120 volts?

When it comes down to it, the main advantage of 240-volt power over 120-volt power boils down to one simple point, and it is referred to as Joule’s Law, which is : Power is equal to voltage times current. Twice the voltage will transfer twice the power.

Is 240V more efficient than 120V?



240V is most common for electrical appliances which require more power, such as a dryer, electric stove, or hot tub. There is no difference in efficiency in our heaters between 120V and 240V (or any other voltage). The reason why 240V is advantageous for appliances and heaters in a home has to do with amperage.

Is a 240V motor more efficient than 120V?

The performance of our 120V and 240V motors are identical. Our ¾ and 1hp units are available in 120V or 240V and the pattern size is the same for either option and there is no difference in the efficiency of either motor. If you already have 120V power available, go with that.

Is it cheaper to run a 110 or 220 air conditioner?

A quick answer: Probably nothing. This is a common misunderstanding about how electricity works and how the power companies charge you for it. The point often noted for the money saving argument is that the amperage is half as much when running grow lights on 220 volts instead of 110 volts.

Why does America use 120V?

Now, historically speaking, one of the main reasons why the US stuck with 120V as its standard power supply largely has to do with the fact that it was initially tied to carbon filament lighting.
