An extension cord is a necessary thing in every home. It may be necessary in the case of connecting several devices to a single outlet or in a situation when vital household appliances are located too far from the connector. The second option is considered more dangerous, especially if the equipment is powerful and is connected in this way for a long time. Most often, apartment and house owners are concerned about whether it is possible to connect large household appliances through an extension cord, for example, a refrigerator. To answer it, you need to study the topic in more detail.

Which extension is suitable for the refrigerator: characteristics

Extension cord with four connectors and grounding

This variety is considered safer.

Among the various options for connecting household appliances to the network there are several main ones:

  • directly to the wall outlet;
  • ordinary extension cord;
  • network filter for the computer.

It happens that during the redevelopment of the kitchen or repair the refrigerator is removed from the outlet for too long a distance, which does not allow you to connect it directly. The best option is to use an extension cord, but how to choose it and which one is right for powerful hardware? When choosing an extension cord for a refrigerator, first of all you need to pay attention to the wire, the main unit with sockets, as well as the plug.

Wire and its characteristics

Two-core extension cord

The cross section of this wire is less than three-core, which means it can withstand less load

Before you buy an extension cord, you need to pay attention to its wire. We are interested in its three main characteristics:

  • length;
  • cross section;

As for the second parameter, the shorter the extension cord, the “weaker” its resistance. The flow of charged particles (electrons) will take less time to overcome the path. Therefore, the actual loss of electricity in a short cord will be less, which means that there will be no voltage drop. You also need to consider that too long extension cords interfere when working in the kitchen. If necessary, too long the wire can be shortened by yourself.

One of the main characteristics of the cable is its cross section. The greater its value, the greater the load will withstand the extension cord. The cross section depends on the diameter of the copper rod, which is under insulation, as well as on the number of wires. Electricians advise to use extension cords in which the diameter of the conductor is at least 2.5 mm.

An extension cord with a capacity of 2200W or higher is suitable for connecting a refrigerator.

Power socket

Extension cable with three lockable connectors

Such a product is suitable for a refrigerator, but on condition that the other two sockets remain free.

To connect the refrigerator, it is better to use an extension cord with a single outlet, so that there is no temptation to connect other equipment in parallel with the refrigerator - a mixer or the like. It is good if free sockets are closed with protective caps - in case of liquid getting on the extension cord they will protect against short circuit.

It should be noted that the more outlets occupied in the extension cord, the higher the load on it.


The plug must be securely fixed in the wall socket. In the case of chattering, the quality of the contact may deteriorate, this will lead to heating of the elements, and then to melting and even fire. There are several varieties (standards):

  • C1-b is the old type found on Soviet household appliances. There are no grounding contacts. Not always compatible with the sockets of the new sample. An adapter may be required.
  • C1-a - standard Russian plug, also without the possibility of grounding.
  • C2 ("Schuko") - plug with separate terminals for grounding. The most popular, reliable and safe form.

Grounding contact - a necessary component of the outlets in the extension cord. It is needed to protect against accidental increase in voltage in the power grid.

Safety device

Good extension cords have protection against short circuit (short circuit) and overload - a special device that automatically turns off the extension cord in dangerous situations. The protective device includes a safety element that cuts off power in case of short circuit and a thermal switch that reacts to the heating of the device. Most often, these components are part of a single unit and are equipped with a power button that is taken out.

Precautions in cases where the extension cord is not suitable

Back wall of the refrigerator

The use of extension cords and tees when turning on large household appliances by non-electricians is not welcome

Using an unusable extension cord is not recommended for a long time. If you still can not avoid the use of doubtful cord, it is recommended:

  • constantly check the device, if the wire or plug heats up during operation, it is better to immediately turn it off;
  • If sparks, traces of melting or the smell of burnt plastic appear, you must immediately turn off the refrigerator or the automatic machine in the dashboard.

Although electricians and security specialists from public utilities do not recommend using extension cords to connect household appliances, in some cases this cannot be done. It is important to ensure reliable connection of the refrigerator plugs and extension cord with the appropriate sockets. Then the operation of the devices will not cause any trouble for the owners.
