In USA, Canada - and other countries where a 60 Hz standard electricity supply service is used - small air-conditioning units, intended for mounting below windows, are available for use on regular 110 - 120 volt outlets. They use either up to 1,800 watts or up to 2,400 watts.
A North-American 120 volt receptacle (socket outlet) is a 'duplex' (twin) outlet with a combined rating of 15 amps unless a link arrangement at the back of the receptacle is broken, in which case, the two 'halves' of the receptacle would be supplied from individual 15 amp circuits from the supply panel, allowing 15 A each.
The design of the duplex receptacle is such that the two outlets are arranged vertically. Because of this, both outlets can only be used simultaneously if appliances having cables fitted with "in-line" plugs are used.
If a grounded 3-pin plug with a cable exiting from it at 90-degrees (like British 13 amp plugs) is fitted to the cable of a relatively high-current appliance - such as an air-conditioner unit - then only one such appliance can be used if it is plugged into one of the duplex receptacles because the appliance's cable covers the other receptacle!
For this reason, air-conditioning units are supplied with cables whose plug is at right-angles to the cable (called an 'AC cable') - meaning that only ONE receptacle outlet can be used.
That scheme prevents the duplex outlet from becoming overloaded (i.e. exceeding 15 A).
So, the simple answer is that an AC unit can only be used with a normal 120 volt 15 amp receptacle if it is connected with an AC cable and not a regular cable ("'regular" meaning a cable with an in-line plug). Otherwise, there is the possibility of overloading the receptacle.
To be able to let the sales person know which kind of air-conditioner you want - so that you don't buy a unit that would overload your wiring - before you buy one it is best to find out for sure if the regular outlet you want to plug it into can safely support a continuous current draw of 15 amps - as would be the maximum amperage used by 1,800 watts 120 volt air conditioning units - or 20 amps, as would be the maximum amperage taken by the 2,400 watts 120 volt units.
Safety Warning
If you use one of those small air-conditioners you must take care not to overload the house wiring by using any other large home appliances plugged into other receptacles that are wired into the same circuit.
Using a small electric light, hi-fi unit or television may be ok, but don't try to use a powerful hair dryer or vacuum cleaner at the same time as the air-conditioner is running.
Most likely the resulting current overload would cause the circuit breaker to trip - to cut off the power before anything catches on fire - but it is wiser not to do it!
Note: Large air-conditioners take a lot more power so they can only be used on a 240 volt branch circuit. (It must have the right kind of outlet, wiring and circuit breakers for 240 volts.)
An earlier answer that does not really answer the actual question:
Air-conditioners are devices with higher consumption of electricity
if it is plugged in a normal house plug it will intake large amount of current which will pass through Power Meter and the filament (element) present in it will burn out. (No, it is the house wiring which might catch on fire if the circuit breaker failed to trip to cut off the current.)
This may even affect the internal wire connections..which may cause fire due to electrical sparks.It is highly dangerious to plug it in plug. (???)
If, over the next 7 days, no changes are made to improve the above earlier answer, it will be moved over to the Discussion page.
If you are lucky the fuse will blow. If not the refrigerator might catch fire.
It is not recommended to rewire a regular plug to a hairdryer as it can be unsafe and may void the warranty. It is best to purchase the correct plug for your hairdryer or consult a professional electrician for assistance.
It may work but will probably surge it...power coming in from both directions
If you are talking about the standard cigarette lighter socket in an automobile, you can only use devices that can run on 12 volts DC ((most modern cars) within the rated AMP load capacity. A standard house outlet is designed for 110 volt AC devices that have a 110 volt AC source
Different plugs are designed so that you can't plug an appliance into the wrong voltage. A dryer is usually 220-240 Volts and your standard outlet is 110-120 Volts. You can't do what you suggest.
It is generally not safe to plug a refrigerator into an extension cord because it can overload the circuit and pose a fire hazard. It is recommended to plug the refrigerator directly into a wall outlet to ensure safety.
The recommended height for installing a refrigerator plug is typically around 4 to 6 inches above the floor.
An energy efficient refrigerator is a better choice than a regular refrigerator and is not too expensive. Matter fact it is around the same price as a regular refrigerator.
because you didn't plug it in, or you broke it.
Everything they use a regular refrigerator for. Subzero is a type of refrigerator, but it is also a brand of refrigerator. They are basically what they sound like, a refrigerator/freezer that reaches and hold subzero temperatures.
If you are lucky the fuse will blow. If not the refrigerator might catch fire.
No, it is not recommended to use a regular light bulb in a refrigerator because the heat generated by the bulb can affect the temperature inside the refrigerator and potentially spoil the food. It is best to use a refrigerator-specific light bulb that produces less heat.
You should be able to plug it right in, unless there is something wrong with it.
To reset a refrigerator compressor, unplug the refrigerator for about 5 minutes and then plug it back in. This can help reset the compressor and potentially resolve any issues it may be experiencing.
Need to know what type of dryer.
The dimensions of a regular size refrigerator typically range from 28 to 36 inches in width, 60 to 69 inches in height, and 28 to 34 inches in depth.
It is generally not safe to use an extension cord with a refrigerator because it can overload the circuit and pose a fire hazard. It is recommended to plug the refrigerator directly into a wall outlet.
