A wide variety of household appliances gives rise to the variability of their connection to the network. A new garden appliance may well not work if connected to a low power extension cord. A power strip is needed for electrical appliances whose power is so high that they cannot be installed directly into the outlet or through a standard extension cord.

As a rule, such a need arises during repairs: most power tools have a lot of power. The next aspect that attracts users in power extension cords is the length of the wire; without a wire of sufficient length, it is almost impossible to work in a summer cottage.

What is the difference between a household extension cord and a power cord?

Popular models of power extension cords are very different from their household counterparts:

  1. The power of the connected equipment - devices with a power of 3 kW or more can be connected to a power extension cord, such high rates are not required in everyday life, but will be very useful for repair or garden work;
  2. Cord length - a power extension cord can be moved away from a stationary power point even by 50 m, this is useless in an apartment, but for outdoor work, a long length becomes a real salvation;
  3. Reliability - the power extension cable is much better protected from the factor of external influences. With double-insulated cables and sockets with enhanced protection, the risk of electric shock is reduced to zero.

How to choose a power extension cord, taking into account individual characteristics

The first thing that the future owner of a power extension cord should pay attention to is the cross section of the wire and its marking. This factor will directly affect the possible load, the maximum allowable for a particular extension cord.

  • Wire with a cross section of 0.75 mm2 able to withstand loads up to 6 A, which is equivalent to 1.3 kW - such a cable will not withstand the load of powerful tools and is only suitable for household appliances;
  • Wire with a cross section of 1 mm2 withstand loads up to 10 A, which is equivalent to 2.2 kW - this cable will withstand the voltage from the operation of small tools;
  • Wire with a cross section of 1.5 mm2 withstand loads up to 16 A, which is equivalent to 3.5 kW - professional equipment remains beyond the capabilities of the cable, but it is best suited for any personal construction tools.

Subsequent sizes from 2.5 to 120 mm2 - the best options for people whose careers are related to construction and repair, in which powerful tools and equipment cannot be dispensed with. In order to determine which cable section will be ideal for a particular person, room and tasks, you can use a simple calculation scheme:

  1. Calculate the power of all electrical appliances in the apartment: the value will turn out to be impressive, and hardly anyone will use all the appliances at once, but you need to know the upper limit for safety reasons;
  2. Add the previous value and the sum of the powers of all lighting fixtures in the room. The final figure will reflect the maximum load limit. For example, the indicator is 10 kW;
  3. Use the table below, find the desired section, for an indicator of 10 kW, you can choose a cable with 4 mm copper conductors2 power 380 V.

Among the brands of wires, you can most often find PVA options, although their characteristics are far from ideal. A summary table will help you choose the brand of wire depending on your needs.
