In private buildings and apartments of new buildings, the wiring of which is made using three-conductor wiring, the problem of grounding is usually solved easily. But how to connect an outlet with grounding in the houses of old buildings, not everyone knows.
In such houses, the wiring is made in the form of a two-wire line, because of this the task is somewhat more complicated. To solve it, you will need to take a number of additional actions. These operations usually boil down to the organization of another (grounding) core, stretched from the flat panel to the grounded electrical access shield.
Installation of a grounding cable
When carrying out electrical work, allowing you to easily connect to the network outlet with grounding, the following options are possible:
The isolation of the wires supplied to the apartment for the convenience of the connection is made in different colors. The ground wire in accordance with the standard has a mixed yellow-green insulation, while the phase conductor is usually made of brown or red sheath. The “zero” wire in most cases is performed in blue or blue insulation.
If there are junction boxes in the apartment, the connection can be made directly to them (if there is a third grounding conductor, of course).
Types of sockets
Directly Before connecting a double grounded outlet, you will have to perform the following preparatory operations:
Connecting to a switchboard Further manipulations related to connecting the outlet are usually reduced to the following operations:
In conclusion, it is necessary to warn you that before carrying out the full range of measures for connecting the outlet, be sure to remove the power supply from the entire apartment. Such a shutdown is usually done by turning off the corresponding automaton or unscrewing the plugs.
