How about choosing too many meters?

When many residents choose to buy electric meters, they are not sure how big they should buy at home, so there will be electric meters with larger rated current and voltage than their home lines. Then, how about buying a bigger meter? How about choosing too many meters? Today, Bian Xiao will introduce you to the purchase of electric meters.

1. What are the consequences of choosing rice?

If the selected ammeter is greater than the rated voltage of its own circuit, parts or lines of the ammeter may be burnt out during power consumption, and the data reading of the ammeter will have great errors. Therefore, when choosing an ammeter, we must first understand the specifications of current and voltage, because the ammeter voltage is divided into high and low, low voltage is 220 volts and 380 volts, and high voltage is 100 volts and 57.7 volts.

Second, what should I do if I choose the meter?

The easiest way is to take the meter to the store you bought and change it to a suitable one. Under normal circumstances, there will be no wrong choice of meters, because the power supply company will measure the voltage and current in residents' homes before installing meters, and then calculate the appropriate meters according to the calculation method of electricity.

3. What size of rice is suitable for ordinary families to buy?

It depends on the electricity of an ordinary family. If the electric power is 13200 watts, it is enough to choose a 60-year single-phase meter. If the total electric power exceeds 13200 watts, you can choose 100a single-phase meter.

If you live in a villa, try to choose a three-phase meter, because there are many lines in the villa and the current and voltage are relatively large. When choosing a three-phase electric meter, you can choose it according to the current. For example, when the current is greater than 100a, choose the three-phase voltage as 100A.

4. What are the normal current specifications of single-phase and three-phase meters?

Common current specifications of single-phase meters are 1.5a, 2.5a, 5a, 10a, 15a, 20a, 30a.

Common current specifications of three-phase meters are 0.3a, 1a, 1.5a, 10a, 20a, 30a.
