How many amps do most appliances use?
James Olson
Updated on March 25, 2026
An amp is the amount of electrical current that flows through a circuit. In most homes, lighting and small appliance circuits are 15 or 20 amps, and major appliances are on 20, 50 or even 60 amp circuits.
How do you determine how many amps an appliance uses?
To determine the number of amps any one device pulls, you must know the wattage of the device, and the device’s voltage.
- Determine the number of volts and watts required by each device to be added to the circuit.
- Divide the number of watts required by the volts to determine the needed amperage.
Which appliance has the highest electrical rating?
These are the top 5 electrical appliances that use the most electricity:
- Refrigerator: consumes a third of all the electricity you use.
- Washing machine: control it with the Happy rate.
- TV: the goggle box gets smart.
- Oven: better if you keep it clean and closed.
- Computers: not as innocent as you might imagine.
What appliances use 13 amps?
Plugs for appliances rated between about 700 watts and 3000 watts (the maximum rating of a wall socket) should be fitted with a 13-amp fuse (coloured brown). For example: 13A Fuse – Washing machine, dishwasher, microwave, kettle, toaster, iron.
How many amps does a 65 inch TV use?
At maximum capacity, that number jumps to 195W. Samsung 65″ Class Q90T QLED 4K Smart TV: The Q90T consumes 120W under normal circumstances, but at maximum, can run up to 295W, well beyond the TU-8,000.
How many amps does a 55 inch TV use?
TV Wattage: How Many Watts and Amps Does a TV Use
| Screen Size (Inches) | LED | LCD |
|---|---|---|
| 42 | 57 | 120 |
| 50 | 72 | 150 |
| 55 | 80 | 180 |
| 60 | 88 | 200 |
How many amps does a fridge use?
Ratings of commonly used household appliances
| Domestic Portable Appliance | Amps Used | Watts Used |
|---|---|---|
| Fridge | 0.65 | 150 |
| Freezer | 0.86 | 200 |
| Mini Fridge | <0.5 | 100 |

How many amps does a small fan use?
Low settings use less amperage while higher settings use more. For example, an average ceiling fan set on low speed uses about 0.25 amp, on medium speed about 0.4 amp, and on high speed about 0.6 amp.
How much amperage does an appliance need?
You should know just how much amperage each appliance draws when it is in operation and the table below is a good quick reference for the most common appliances and how much Amps they can draw. Note that the Amps below are typical. Some appliances may require more or less depending on their efficiency and size.
Where can I find amperage ratings on appliances?
If you need to know exact amperage ratings you can check the data plate on any motors, appliances, or electronic equipment you are using. If you can’t locate a data plate with this information, check the appliance or electronic equipment owner’s manual.
How many amps does a portable air conditioner need?
The best battery-powered unit – the Zero Breeze Mark 2 – can deliver 2,300 BTU of cooling power with just 24V electrical potential. That means it needs 27 amps to power the whole AC unit. That is, in comparison, higher amperage than it’s needed to power an 18,000 BTU portable air conditioner (about 13-19 amps).
How to calculate the maximum current from an appliance?
When you see an appliance with a label that only lists the wattage, you may need to figure out the actual maximum current it will draw. There is a simple formula for converting the maximum wattage rating of an appliance to a maximum current number. A = W/V Current (A or amps) equals watts (W) divided by voltage (V), or more simply, A=W/V.
