Extension cord for refrigerator washing machine

Hello! And where did you see such "13 amperes". All extension cords that are now sold are designed for 16A, and less often for 10A. In principle, this can be done, but what kind of boiler is plugged into the socket? Most likely, the problem will be that the boiler and the washing machine are in the same outlet is a lot, do they turn on at the same time or do you turn off the boiler while the washing machine is running? Do you have machines for other outlet groups in the electrical panel? Here it is rational even through an extension cord, even though an outlet to lay from another line - then it will be correct.

If this is not possible, then you may well use it. The washing machine at its peak consumes from 1000-2500 watts (household). This is from 5 to 10 Amperes. What refrigerator? Old or new? Drip defrost system or no-frost? It consumes about 200-300 watts on average during operation. But at the time of start-up, it consumes a fairly large current (if the refrigerator is not an inverter). This means that a maximum power of 2500 + 300 = 2800 watts will be connected through the extension cord. This is 12A.

That is, the answer to your question is - yes, you can connect the refrigerator and the washing machine through an extension cord, but watch the heating of the plugs and sockets, as well as their condition.

But, again, what kind of boiler do you have? If the wiring is laid normally, and there is an automatic machine on the sockets as it should be for 16A, then everything will not be able to work at the same time.
