As a professional supplier of intelligent voltage protectors, we are well aware that different household appliances have different requirements for current.
12A household appliances
Small electric heaters: The intelligent voltage protector supplier tells you that some small electric heaters with lower power have a power of about 2600 watts. According to the power formula P=UI (P is power, U is voltage, I is current, and the household voltage is generally 220V), the current can be calculated to be about 12A.
13A household appliances
Washing machines: The power of ordinary household washing machines is generally around 200-500 watts. Some washing machines with larger capacity or more functions may have a power of 1000-1500 watts, and the corresponding current is below 10A to about 7A. Although the current of washing machines is usually less than 13A, there may be a large current shock when some special functions are running or the motor starts. Therefore, when choosing fuses or circuit protection, the large instantaneous current will be taken into consideration, and the 13A specification will be adopted.
Refrigerators: The power of ordinary household refrigerators is between 100-300 watts, and the current is about 0.5A – 1.4A, but the refrigerator compressor has a larger current when starting, usually 5-10 times the normal operating current, and the instantaneous current may be close to or exceed 10A, so it may also be adapted to 13A circuit protection or socket.
15A household appliances
Microwave oven: Common household microwave ovens have a power of 600-1500 watts, and the corresponding current is about 3A-7A. The supplier of smart voltage protector tells you that when the microwave oven is working, due to the characteristics of its magnetron and other components, the instantaneous current at startup is large, which may be close to 15A, so its circuit design and socket selection generally consider adapting to 15A specifications.
Oven: Small household ovens generally have a power of 800-1800 watts and a current of about 4A-8A, while some larger professional ovens may have a higher power, may generate a larger current during startup and heating, and may require 15A current support.
20A household appliances
Wall-mounted air conditioners (2P): The cooling power of 2P wall-mounted air conditioners is generally around 1500-2500 watts. The heating power plus the auxiliary electric heating power may reach about 3000-4000 watts. According to the power formula, its operating current is about 7A-18A, and it usually needs to be equipped with a 16A or 20A socket.
30A household appliances
Floor-mounted air conditioners (3P and above): The cooling power of floor-mounted air conditioners of 3P and above is generally around 2500-4500 watts. The heating power plus the auxiliary electric heating may reach 5000-8000 watts or even higher, and the operating current is around 11A-36A. The supplier of intelligent voltage protectors tells you that some high-power floor-mounted air conditioners may need to be equipped with 30A sockets or dedicated circuits.
For some small electrical appliances, the current specification is often around 12A, such as some exquisite and small electric heaters, which can bring you just the right warmth in winter; and washing machines and refrigerators that are frequently used in daily life, considering special working conditions such as the moment of motor starting, are mostly adapted to the 13A specification, stable operation to ensure home convenience; microwave ovens, ovens and other kitchen assistants, due to their working characteristics, have a larger instantaneous current, usually corresponding to 15A, helping you to easily cook delicious meals; the current carrying capacity of 20A is often used by 2P wall-mounted air conditioners to ensure comfort in hot summer and cold winter; as for 30A, it is the standard configuration of high-power appliances such as 3P and above cabinet air conditioners, creating a pleasant home environment for you in all seasons.
