How to calculate the load on an electrical outlet?

Question

Physics

Hello,
There is a socket (double), it comes with: a laptop, a refrigerator, a kettle and a lamp. I want to replace my laptop with a computer + monitor, but it seems that I turn on too much anyway (there is no other outlet nearby). Where can I find information about what load the sockets can withstand, as well as the power of the connected devices (I'm not sure that the documentation on the devices has been preserved)?

Answer 1

Usually sockets are designed for 10 Amperes, 10 * 220 = 2200 watts of power, but it's not even about the sockets, but the cross section of the conductor to which the socket is connected. If the outlet is double, then most likely one line comes. If the house is not old, then there should be a section of 2.5 square meters. mm. copper cable, provided that the installation was correct and all connections are reliable, then a cable with such a cross section should calmly and for a long time withstand a current of 20 amperes, 20 * 220 \u003d 4400 watts of power. To accurately understand the load on the sockets, you can buy current clamps and measure the power in the shield, after turning off all unnecessary sources of consumption.
