When choosing a machine, it is important to consider the total power of the connected devices.
For example, a machine is needed to connect malta email list 149912 contact leads kitchen appliances to the power supply. Let’s say a coffee maker (1000 W), a refrigerator (500 W), an oven (2000 W), a microwave oven (2000 W), and an electric kettle (1000 W) will be connected to the socket. The total power will be 1000+500+2000+2000+1000=6500 (W) or 6.5 kW.
It should be taken into account
That a higher power consumption may be required, since during operation it may be necessary that were not initially taken into account. To provide for this why is online reputation so important? situation, an increasing coefficient is used in the calculations of total consumption.
Let’s say that by adding additional electrical equipment, the power needed to be increased by 1.5 kW. Then you need to take the coefficient 1.5 and multiply it by the calculated power obtained.
In calculations it is sometimes advisable to use a reduction factor. It is used when the simultaneous use of several devices is impossible.
Let’s say the total power of the kitchen wiring is 3.1 kW. Then the reduction factor is 1, since the minimum number of devices connected simultaneously is taken into account.
If one of the devices cannot be connected to the others, then the reduction factor is taken to be less than one.
Calculation of the rated power of a circuit breaker
The nominal power is the power at philippines numbers which the wiring does not disconnect.
It is calculated using the formula: To connect other
·CT – current strength that can pass through the circuit breaker (Ampere);
· cos(φ) – the value of the cosine of the angle that takes the value of the phase shift angle and voltage.
The value of the cosine is usually equal to 1, since there is practically no shift between the phases of the current and voltage.
From the formula we express the ST: To connect other
CT = M/N,
We have already determined the power, and the network voltage is usually 220 volts.
