Amperage Management: A Comprehensive Guide to Understanding and Reducing Electrical Consumption for Every Appliance and Electronic in Your Home

Having information about the amperage drawn by the appliances and using it is very much beneficial to reduce electrical consumption. This article will guide to all about the electrical consumption by the commonly used home appliances, electric vehicles, RVs, welders, etc. also you should use the right wall outlets, circuit breaker, and gauge wire so that you may not suffer from overloading, fire hazards or damage to the appliance,

Power consumption by electric vehicle:

Before buying an electric vehicle you need to know about the power consumption by the vehicle whether it is a car, bike, bus, boat, train, scooter, etc.

Electric car:


Tesla model:


Lucid air: 

If you are selecting lucid air then you need to know about charging cost, amperage, time to charge the car, and kWh per mile so that you can decide which is better.



Electrical consumption for every appliance:

It is good to know about the electrical requirements of the appliances before you buy them as after spending your money to buy the appliances if you come to know that the electrical requirements are not sufficient for the appliances it will be a waste of money so following are some points to check in the appliances:


There are many types of fans and you should buy the fan after checking the power, amperage, voltage, and most efficient fan of each fan such as tower fan, table fan, box fan, ceiling fan, etc. 


Air conditioner:

  • Buying the air conditioner according to the power consumption and amperage is a good option. There are many types of air conditioners and each does have its own electrical requirements and components so you should check each type such as window ac, Portable ac, wall ac, etc.  
  • If you are having any confusion about which to buy, you can compare the window ac with the portable ac to find out the efficiency, cooling efficiency, amperage, and noise difference between them and buy accordingly. 
  • With an air conditioner, another option mostly everyone uses the heat pump but buying anything is not good as the heat pumps are used to heat a room Or home in winter and cool the room in summer. So you check which is the heat pump with the highest HSPF, amperage is drawn then buy the heat pump. 
  • If you are thinking of buying a generator to run the air conditioner in case of electric failure then you should first know about what size of generator you need and the amperage drawn by a specific generator. 


  • For a refrigerator, you need to know about the amperage used by different refrigerators such as normal refrigerators, small refrigerators, Fridges, freezers, etc.
  • You should buy it after checking which is the most efficient refrigerator as there are many types of refrigerators such as dual refrigerators, French doors, and mini-refrigerators. 

Other appliances:

Including the above-mentioned appliances, there are many appliances that are commonly used in houses such as dishwashers, coffee makers like dolce gusto, TV, computer, and laptop, if you are living in a cold place it is common to use an electric fireplace to warm themselves, microwave, using a roof heating cables in the location of cold weather is common, water heater, hot tub, electric stove, etc. All these appliances do require some amount of electricity to run and that you can easily find on the specifications on the application for example wattage and amperage required by a TV, if you are using a dryer to need to check all the electrical components such as amperage, voltage, wattage and the time taken by the dryer to dry the cloth so that the energy consumption is less. 

Wall outlet, gauge wire, amp circuit breaker:

For running the home appliances you should need to have knowledge about the wall outlet, gauge wire, and amp circuit breaker so that you can prevent yourself from causing any fire hazards or damage to the appliances. 

Wall outlet:

Basically, the wall outlet in the residential area is 120 volts with a 15 amp outlet which is used for small appliances, and a 20 amp outlet which is used for large appliances. You should buy the wall outlet according to your need and wall outlet is available in various types such as:

  • Combination outlet. 
  • 15 amp duplex receptacle. 
  • Ground fault circuit interrupter outlet. 
  • Arc fault outlet. 
  • Temper-resistant receptacle. 
  • Surge suppression outlet. 
  • Rotating outlet. 
  • Ungrounded outlet

You can choose them as each has its own specifications, function, and benefit. 


Gauge wire:

To protect your house and appliances to get damaged or catching fire you should know the amperage the wire can handle and use the gauge wire accordingly as there are many types of gauge wire and each wire carry a different amount of amps such as:

  • 4 gauge wire. 
  • 6 gauge wire. 
  • 8 gauge wire
  • 10 gauge wire. 

For example, a 4 gauge wire is able to handle the amperage of upto 70 amps depending on the wire type like copper wire or aluminum wire. 


Pole breaker:

in the case of the circuit breaker, they basically two types of breakers such as single-pole breakers and double-pole breakers but you should know about the amps a pole breaker is of so that you have knowledge of the amps and you don’t overload the circuit. the main function of the pole breaker is to trip the circuit in case of overload and prevent the circuit to catch fire and damage the appliances. for example a 30 amps double pole breaker will trip when the circuit gets continuous electricity of 100 watts.


Power supply faults:

there are many faults a person faces while playing games with a gaming console ps4 such as:

  • Shortage in the internal power supply.
  • The problem in fuse and power management.
  • A problem with the power button.
  • The problem is with the power cord.
  • A problem with connecting the ps4 with the power cord.
  • Fault in the power strip.

if you are having a ps4 you should learn how to repair the ps4 faults. the following are some ways to check the problem in ps4:

  • Check the Power strip.
  • Check the PS4 power cord.  
  • Check the power supply unit of the PS4.

Moisture maintaining appliances:

Using moisture-maintaining appliances is greatly seen by many people but they are not aware of how to use them effectively so that it does not add much to the electricity bill. The moisture-maintaining appliances such as a diffuser which ranges from 0.35 amps to 1 amp do not consume a lot of electricity but it doesn’t mean that you are using the diffuser 24 hours, air purifier, and dehumidifier does draw different amperage at different mode due to some components they draw more amperage like compressor, coils, fans, etc, a humidifier is also a moisture maintaining appliance which is used during winter and the amperage consumption vary according to the setting of the humidifier like low, medium, high.


Amperage consumed by welder:

For a person who does things to work as a welder or who is already working as a welder the amperage breaker for a welder is from 30 to 40 amps so before working they should know about various points such as:


Recreational vehicle:

Having a recreational vehicle and just traveling is not sufficient, you should have proper knowledge about the electrical components of the RV such as the amperage, wattage, etc. you should know about the amp hours an RV needs to run all appliances. The main appliance which consumes most of the power is an RV AC as the amperage drawn by the AC Is based on the BTU. For example, an RV AC having a capacity of 10000 BTU has a maximum running amperage of 8.70 amps, etc. You need to know about all this in case to protect the RV from any overloading.
