Is the water and electricity loss fee legal?

The water and electricity losses are legal, as follows:

1. Whether it is reasonable for a property company to collect water and electricity losses from users depends on the form in which the property company collects water and electricity.

2. Collect some contracts between real estate property management companies and tap water, electricity, heat, water supply, power supply and heating. It's free. On the basis of the unification of the property management company, the water company, electricity and heating are summarized, and the water, electricity and heating are paid by the company, and then the owners of the property management company pay the relevant expenses.

Theoretically, the water, electricity and heating fees should be collected by the supplier, that is, the water collected from the owner belongs to the company, the electricity is collected by the power company, and the power company supplies heat to the heating company. However, in practice, the operation is convenient, and many residential buildings are often collected by property management companies for utilities and heating costs.

4. Some property management companies are entrusted by water supply companies, power companies and heating companies to collect relevant fees from each owner. The property management company accepts the entrustment of the water supply company, electric power company and heating company, and then transfers the collected fees to the water supply company, electric power company and heating company, and the water supply company, electric power company and heating company pay certain service fees to the property management company.

The calculation method of wire power loss is as follows:

1, calculated linear resistance: 20℃, aluminum resistivity: 0.0283 Ω mm2/m; When copper is 0.0175 Ω mm2/m, the total length of single-phase 220V circuit is 2*L, the total length of three-phase circuit is 1.7*L, and the cross-sectional area of conductor is s, then the line resistance R= resistivity * total length/s. ..

2. Line current: The current value can be measured or calculated. Single-phase 220V line current = equipment rated power /220, and three-phase line current = equipment rated power/rated voltage/1.732/ power factor.

3. Line loss: line loss power of single-phase 220V circuit = line current square *R, and line loss power of three-phase circuit = line current square *3* power factor square * R. ..

4, three-phase imbalance, calculated according to the maximum current.

To sum up, the owner is the end user, and only needs to pay the water and electricity fee according to the standard approved by the price department, and does not need to bear the water and electricity losses.
