How Many Amps Does A Dryer Use: A Comprehensive Analysis

Nowadays, almost every family around the globe possesses a hair dryer in their house, it’s a popular household appliance. However, people only care about the drying performance of the dryer and pay very little attention to its electric current along with energy rating. Do you know how many amps does a dryer use? In the case the issue never crosses your mind, this article could provide with the answer and some interesting information.

How Many Amps Does A Dryer Use

In most of the case, you should be able to find the rating of the dryer electric current on the information label of the appliance. Otherwise, you may have to do some conversions. Old dryers often use 15 – 20 amps but modern products could go as high as 30 amps. Generally speaking, hair dryers are surprisingly powerful and energy-hungry for their sizes. Therefore, it’s very unwise to underestimate the hair dryer influence on the house electrical system.

Before you buy a fryer, you must ensure that its handling characteristics and electric ratings are suitable for your house. It’s not exactly an expensive investment that requires thorough inspection but to buy an electric appliance without proper consideration is strongly ill-advised nonetheless. Beside the fact the dryer may be unable to satisfy your need, you would risk the integrity of the house wiring arrangement if you buy on a whim.

The Consequences Of Underestimating The Dyer Impact On The System

So you are in rush to get ready for work, you grab your dryer, plug it in and without warning, you are surrounded by darkness. There are many things that could cause power overload but if they often happen when you drying your hair, your dryer may be the culprit. In order to get rid of the constant outages or at least alleviate the situation somewhat, you could try out these methods below:

Check Out The Circuit Breaker

The circuit breaker job is to monitor the flow of electricity on a circuit and disconnects power when the current reach above the determined level. In order to avoid overheating and prevent electrical fire, it’s important not to choose a circuit breaker with a high rating. On the other hand, a breaker with a low rating is also inappropriate since it’s going to “trip” continuously which shall prove very frustrating for most people.

For example, if your dyer rating is 30 amps but your breaker is rated at 20 amps, the breaker would trip every time you use the dryer. In contrast, if you use a 40 amps breaker on a circuit that is designed to carry 30 amps, the current would be allowed to pass through undisturbed till it exceeds 40 amps. This is extremely dangerous since by the time the breaker could do its job, the entire system may overheat already.

Reduce The Number Of Appliances

One of the simplest ways to solve power outages caused by circuit overload is to reduce the number of appliances in use on one circuit. For instance, in the summer/winter, people often use many devices to keep the house temperature at an acceptable level. Leaving multiple appliances on at the same time may generate a load that exceeds the capacity of the electrical wiring.

For the solution, it’s recommended that you disperse all plugged in device across the house circuits. You could use extension so you don’t have to concentrate many appliances on a particular circuit. In order to figure out the number of the circuits you have in the house, you should check out the breaker box. If needed, you could call an electrician over and let him take a look at the breaker box as well as the house electrical system.

Increase The Circuit Power Rating

Homes that are built before the end of the 20th century often have circuits with a rather low power rating compared to modern day appliances. As a result, it could be difficult for you to use hair dryers with high power ratings in such houses. While it’s easy to buy a hair dryer that matches the power rating of the house circuits, you should consider updating the house wiring.

By getting new internal wiring, you would be able to increase the circuit power rating as well as solve a wide range of electrical problems. It’s always good to know that the electrical system of your house is safe, modern and up to date. Technically speaking, you could attempt to do the wiring on your own as long as you have the tools and know exactly what to do. If you need help, there are a lot of places that offer rewiring and maintenance service.

Give Your Dryer Its Own Circuit

If the above methods appear to be ineffective of not feasible to you, you could give your dryer its personal circuit with a proper rating. That should solve your overload issue or significantly reduce the number of times it happens.

“How Many Watts Does A Mini Fridge Use?”: A Detailed Answer

Compact refrigerators, or mini fridges, are primarily used to store foods and drinks in dorm rooms, game rooms, home offices, garages and alike. Thanks to the fridges humble profile, they have a very limited space requirement so you could conveniently place them anywhere you see fit. Nonetheless, you are in for a surprise if you assume that mini fridges use less energy compared to standard fridges simply because they are smaller.

Want to know how many watts does a mini fridge use? Then you could find the answer right down below along with a couple of important information on the side.

What is the cost of running the average mini fridges?

Here is an interesting fact: For most the time, mini fridges actually use more electricity per cubic feet than other standard size fridges. The cost of running a full-size refrigerator is only about twice as much as a compact fridge one-quarter of its size. As a result, a 4.4-cubic-feet compact refrigerator could cost you $27 a year while a much larger 20.6-cubic- feet fridge only cost you $47 in the same time period.

There are two reasons behind this: First, there isn’t a lot of room for insulation. Second, mini fridges have considerably more area per cubic feet to accommodate food and drink which require additional electricity to keep everything cool. Of course, there are many other contributing factors too such as the unit age, the room placement, the defrost setting and so on.

In general, provided that the setting is similar, mini fridges would have lower energy efficiency compare to full-size refrigerators. Most people don’t notice the slight difference in their utility bills though because compact refrigerators often cost you well below $5 per month. To have cold snacks and beverages in your hand while watching sport or playing games could easily justify the less than ideal efficiency.

You should be able to find an eye catchy yellow and black Energy Guide Label somewhere on the fridge body. It would tell you the estimated amount of energy the refrigerator could use in a year along with its projected c cost. Products with an Energy Star rating on their label tend to consume less energy compared to other models.

The estimate electricity usage and associated cost of mini fridges from popular brands

Do remember that the cost could vary a lot in reality, depending on the local utility rates as well as well individual preferences. The products down below are simply examples, there are more products on the market for you to choose. Nonetheless, these examples should offer you a general idea of what to expect when it comes to mini fridges electricity usage and operation cost.

How many amps does a mini fridge use?

The refrigerator ampere is often listed in the manual or on the fridge front/back labels, you could even look for it online. It’s also simple to manually calculate the ampere of a mini fridge, you only need to use this formula: Amperage = Watts/Volts. For example, if you have a 120 Voltage and 240 Wattage then your mini fridge shall have an Amperage of 2.

How many watts does it take to run a refrigerator on a generator?

As a rule of thumb, the generator wattage must be 1.5 times higher than the refrigerator running wattage to start the unit. This is due to the fact that fridge requires an extra jolt of electricity to jump-start its compressor motor. Take a good look at the output rating of the generator in order to make sure it can handle the fridge electricity requirement.

How to take care of your mini fridge?

  • It’s recommended that you keep the fridge away from direct sunlight and heat sources.
  • When you first plug in the fridge, set it at a medium-cold setting
  • Don’t try to squeeze too many things into the fridge. That would leave no room for the cold air to circulate and chill the items.
  • Clean the fridge and vacuum its coil on a monthly basis to maintain an ideal performance.
  • Get rid of all perishable item if you intend to go away for a couple of months.

What Is The Difference Between 220 And 240 Volt Outlets ?

Whenever you want to move your electric appliances, you must have a clear understanding of the difference between 220 and 240-volt outlets. Each appliance needs to be plugged into an outlet that matches its voltage; otherwise, the appliance would not work correctly. As a result, if you intend to relocate your washing machine, microwave, refrigerator and alike, you must ensure that proper outlets are around. Using the right outlet for the right appliance is the key to preserve the appliance quality and avoid potential hazards. In the case you want to know more, down below is additional information about the outlets characteristic and associated issues.

The plug

There are about 15 types of plug currently in use nowadays, each of them come with a letter for convenient identification. The name of the plug has no special meaning so you don’t really have to worry too much about it. Certain plugs could be compatible with both 220 and 240-volt arrangements so do remember to exam the outlet and appliance voltage beforehand. Act carelessly here and you could run into trouble: At best, the appliance would not work as designed which is ill efficient. At worst, the conductor would overheat and that would lead to significant fire hazard.

Important note

As mentioned above, depending on the manufacturer wish, one plug type could have different voltage in different appliances. Therefore, the list of 220V and 240V plugs down below is compiled using both the plug capability and country voltage as references.

There are approximately 13 types of plugs that could be seen on 220V electric appliances base on the plug capability. They are C, D, E, F, G, H, I, J, K, L, M, N and O. Some of these plugs are used across the globe but there are country exclusive plugs as well.  Base on country voltage, there are 12 plugs: A, B, C, D, E, F, G, I, K, L, M and N

What does a 240v plug look like?

There are also 13 types of plug currently in circulation that could be seen on 240V electric appliances base on the plug capability. The 240v plug list is pretty much the same as the 220v one. Similar to their 220V counterparts, some of these plugs could only be found on remote corners of the world. However, base on country voltage, there are only 3 240v plugs which are G, I and D.

The outlet

What does a 220v outlet look like?

220v outlets mostly correspond to their plugs but there are some outlets that are able to accept more than one type of plug. The examples include:

  •  Type B is compatible with Type A and B plugs
  • Type D is partially compatible with Type C, E and F plugs, unsafe
  • Type E is compatible with Type C, E and F plugs
  • Type F is compatible with Type C, E and F plugs
  • Type K is partially compatible with Type E and F plugs, unsafe
  • Type L(16A)  is compatible with Type C plug
  • Type N is compatible with Type C plug

 What does a 240v outlet look like?

The 240v outlet’s compatibility with the appliances is also similar to their 220v cousin. It’s advised that you should connect the appliance plug with an outlet that matches its type just to be on the safe side

The design of the outlet

The average 220/ 240v appliances utilize 3 wires

  • A hot wire: Carries the current to the fixture
  • star
    Another hot wire: Also carries the current to the fixture
  • star
    A copper wire: Ensure user safety

There is no neutral wire here but when one of the hot wire is positive, the other is negative. That arrangement complete the circuit.  However, there is another wire scheme that is employed by appliances like clothes dryers and so on. It consists of 4 wires

  • A hot wire: Carries the current to the fixture
  • Another hot wire: Also carries the current to the fixture
  • A neutral wire: Completes the electrical circuit
  • A copper wire: Ensure user safety

As a result, certain appliances could have up to 4 prongs instead of the usual 3 in their plug.


That is most of what you should know about the differences between 220 and 240-volt outlets, not too hard to take in, right? It could be a bit confusing at first but as long as you get the hang of it then you should have no trouble identifying the outlet. This knowledge would help you a lot when it comes to remodeling the house and rearranging your electric appliance.

The type of clothes washer you have plays a major role in whether or not it should be replaced.

2 Types of Washing Machine

1) Top loading washing machine

This is the type where you load the clothes from the top of the machine. There is a cover that you have to open to load or unload the clothes into the tub that functions as the washing vessel, rinser and drier, as well, if it is a fully automatic clothes washer.

2) Front loading washing machine

Top loading washing machines are also classified as: fully automatic and semi automatic. With this type of washer, the clothes are loaded from the front opening.  Front loading washing machines are very economical to use, because this type consume less water, detergent and electric energy. Compared to the top loading type of clothes washer, studies show that front loading machines produce better washing results.
