The total power of a household appliance is less than 2100W, and the appropriate meter is () A. 380V  5AB. 380V  10AC. 220V  5AD. 220V  10A

The total power of a household appliance is less than 2100W, and the appropriate meter is () A. 380V  5AB. 380V  10AC. 220V  5AD. 220V  10A


The voltage of the home circuit is 220 V, ∵ the total power of household appliances is not more than 2100 W, ∵ the minimum current of the electric energy meter in normal operation: I = Pu = 2100W, 220 V ≈ 9.5 a, ∵ the electric energy meter should choose "220 V 10A", so choose D



I have 18 motors and other electrical appliances with rated power of 1kW, and the total power is about 25kW. How large is the single-phase meter to be installed?
All my electrical appliances are 220 V, and the incoming line is single-phase


Using a three-phase four wire total meter, whether the number of 60A is scientific depends on whether your electrical appliances have more than 220 V voltage or 380 V voltage. The fuzzy power current is like this: for 380 V electrical appliances, the maximum current per kilowatt is calculated as 3a, for 200 V electrical appliances, the maximum current per kilowatt is calculated as 5A. Then you add the sum and divide it by 0.8, because it is related to the life and safety of the meter, In addition, it is unscientific to calculate the a number of watt hour meter and main switch according to the total power in the case of multiple types of transformer···



What do you think of this meter? I want to know how much power this meter can provide
5(60)A 220v 50hz 1200imp/kwh


5A (max. 60a). At 1100w-10kw



What does 1200 imp / kWh mean in digital meter (electronic meter)


Is the number of pulses per kilowatt hour
The pulse indicator of the electric energy meter will flash. When the pulse indicator flashes 1200 times, the value of each digit of the counter will enter one digit, indicating that you have used 1kwh
