In addition, grounding reduces the effects of electrical noise on devices connected to the network. It is recommended to purchase a grounded carrier if it will constantly be used to operate a computer, refrigerator or other similar equipment. If only a temporary connection of devices is supposed, then you can buy a simple copy that does not have grounding.

Before connecting home appliances, the user should make sure that their appliances will not exceed the maximum allowable carrying parameters. If an extension cord for an electric drill is required, then a specimen of 1.3 watts is enough. For a washing machine, you will need a model with a more impressive indicator - 2, 2 kW.

- Condition of cable insulation materials … Extension cords can have either multi-layer or single-layer cables. Versions with only one insulation layer can be operated in environments where there is no high temperature and normal humidity levels. Two-layer models can be used in more extreme conditions, where there is a high humidity level and high temperatures. Similar products will work in cold weather without any problems.
