As it should be choose a suitable electric extension cord for domestic use?
First of all, there are a few questions to answer:
What power should the device be connected to the extension cord
? How many devices will we connect? What will it be
the distance between the socket and the appliance
? Under what conditions will the extension cord work? Usually, in domestic conditions, extension cords with conductor cross-sections smaller than 1.5 mm2 are sufficient. For example, a cable with a cross-section of 1.0 mm2 will allow us to safely connect electrical devices with a total power of up to approx. 2300 W, and a cable with a cross-section of 1.5 mm2 will allow us to safely connect electrical devices with a total power of up to approx. 3500 W. Remember that it is advisable to
distance between the socket and the connected device
did not exceed 50 m.
