Anonymous users2024-02-07The meter is a measuring instrument and will not significantly affect the measurement due to the size of the range.
It's just that the current is large, and the sensitivity is lower when the electricity is small.

Anonymous users2024-02-06There is a difference, that is, the total amount of electricity in your home exceeds 40a, your meter will burn out, easy to cause fire accidents, 40A meter and 100A meter metering is the same, but now the household with 40A meter is a bit small, home appliances are more, with 100A meter is better.

Anonymous users2024-02-05The allowable current is not the same, according to the previous situation, the meter with high current, in the case of small current, the number of meters will be small, but now the technology has been improved, generally speaking, it will not be affected.

Anonymous users2024-02-04To be precise, a 40A is more accurate, because it can detect current that 100A can't detect! It can be understood that the electronic scale can be called "gram", the larger one can be called "catty", and the larger one is calculated in "tons", of course, the use is different, for example, 40a can be used in the office area, and 100a can be used for plant machinery and equipment. When the 40A meter is used on the circuit that exceeds 40A, the error will increase geometrically) The power supply bureau will not install the meter for you casually, they will calculate according to your actual electricity consumption, and the 40A meter household low-power electrical equipment will also be measured very accurately!

Anonymous users2024-02-03Hello: Select the watt-hour meterWhichever is suitableIt is not appropriate to be too big or too small.
The dial of the watt-hour meter will appear [SneakPhenomenon, that is, after the load is powered off, the aluminum turntable will rotate very slowly, no more than one turn.
You know, although it's all a circle, butPower consumptionIt's different, so blindly choose a high-capacity watt-hour meterNot necessarilyTake advantage!

Anonymous users2024-02-02The difference between 10 and 100 is in the amount of current used with electrical appliances!
Ordinary electrical appliances 32 are almost the same, and 100A are almost all used for high-power motors.

Anonymous users2024-02-01Summary. 40A or 60A refers to the maximum load capacity installed by the power supplier to the customer. If the capacity of the electric energy meter fails to meet the power needs of the user; Requests can be made to the power supply department to increase the capacity of a larger single or three phase to meet the demand.
The maximum load capacity of the 220V voltage 40A electric energy meter is that the maximum power consumption of the user is 8800W, if the power supply party installs a current limiting device; If the user exceeds this power load, the power supply will be disconnected to protect the safe operation of the electric energy meter.
The maximum load capacity of the 220V voltage 60A electric energy meter is that the maximum power consumption of the user is 13200W, and what is the difference between the electric meter 40A and 60A.
40A or 60A refers to the maximum load capacity installed by the power supplier to the customer.

The maximum load capacity of the 220V voltage 40A electric energy meter is the maximum power consumption of the user, which is 8800W for the empty trouser chain, if the power supply party installs a current limiting device; If the user exceeds the pure brightness, the power of the electric load will be disconnected from the power supply to protect the safe operation of the electric energy meter.
The maximum load capacity of the 220V voltage 60A electric energy meter is that the maximum power of the user is 13200W, I open a small restaurant, the electricity bill for three months is more than 7,000 fast, the 20A meter used, if you change a 60A meter, will the electricity bill be less.
How not. Hello in.
No, it won't. The meter is only recorded.
Your electricity bill is for your electrical appliances.
The 20 amp meter is small, and the power at home is large, so the meter will not go faster.
No, it won't. Meter records are the same.

1. The ingredients are different. Engineering paint is also a kind of latex paint, the difference between engineering paint and "commercial paint" is that in engineering paint, the content of acrylic emulsion and titanium dioxide and other main raw materials is less, the quality of raw materials is slightly inferior, and the grinding mesh is not enough, that is to say, the fineness is not enough, the surface of the paint film is not delicate and smooth, and the feeling of painting is not very soft during construction. Therefore, when you buy, you can read the ingredient manual to distinguish between engineering paint and latex paint. >>>More
