Tools for working with the electrician in private buildings and apartments of new construction, wiringwhich is constructed using a three-core wiring, grounding problem typically is solved easily.But how to connect a grounded outlet in the homes of old buildings, known not to everyone.
In such houses wiring is designed as a two-wire line, because this problem is somewhat more complicated.To solve it you'll need to spend some additional steps.These operations are usually reduced to the organization of another (grounding) wires stretched from the panel to the apartment driveway grounded electrical panel.
Mounting grounding cable
For electrical maintenance, can be easily connected to a network outlet with a ground following options:
- Electric panel Laying more tires made of copper wire of a certain diameter and stretched from the premises to the access distribution panel with free ground terminals.
- Construction of the so-called "zeroing", the essence of which is to connect the earthing contact outlet for "zero" wire.The professional electricians consider such a way to connect more preferable because in this case it is possible to use the line circuit breakers.
If you have a flat junction box connection may be made directly to them (in the presence of a third grounding conductor, of course).
immediately before the plug socket with grounding, you have to do the following preliminary tasks:
- clean up the ends of the wires, the connecting power to the outlet;
- remove mounted items decorative cover;
- loosen the fastening screws on the terminals, which will be subsequently connected electrical wires.
Connection distribution box Further manipulations associated with connecting sockets, are reduced, as a rule, to the following operations:
- ends of the wires, a plastic derived from the landing box are applied to contacts and are filled to the appropriate terminal holes.Phase and neutral wires can be connected without regard to their functionality (ie, they can be interchanged).In contrast, the grounding conductor must be connected to the terminal block with a special designation, which is a symbol of the earth.
- After wiring socket housing without a cover attached with screws to the mounting plastic box (Enclosures);while the leads neatly tucked into his body.
- Female old-style products are equipped with special tabs that allow you to fix the casing by tightening the screws.
- After fixing the socket in podrozetnik should again check the tightness of the bolts on the terminal, and only then replace the decorative cover.
In conclusion, we must warn you that before the whole complex of measures on the outlet connection, be sure to remove the power supply from all over the apartment.Such a trip is usually made by switching off the corresponding machine or twisting tubes.
