Sockets with grounding are used to power most devices with high power. Computer equipment, refrigerators, dishwashers and washing machines, heating devices( kettles, irons, heaters) - in the operating instructions for all these devices, there is an item obliging users to use a grounded outlet for electricity supply. Otherwise, the obligation to guarantee the repair of equipment will not be fulfilled.
how to connect a socket with grounding
What type of socket with grounding to choose?
In Russia, an F-type socket is used - an outlet with two round holes 4.8 mm in diameter and grounded in the form of protective plates or staples.
The choice of euro-sockets is great enough. Sockets with a protective curtain, with a timer with an ejector, with an indicator of the presence of current, for rooms with high humidity - the choice depends on the conditions of future operation. The choice of the type of outlet depends on the wiring device: for outdoor use external( overhead) sockets, for internal - built-in.
Installation of earthing sockets - internal wiring
Normally, the sockets are installed at a height of about 30 cm from the floor. But for the convenience of using the outlets, another height of their installation is permissible( the height of the installation of the outlet in the kitchen apron is 1 m).
Required tools and materials: level, pencil, punch( if necessary strobleniya), pliers, sharp knife, cross and flat screwdrivers, nippers, gypsum plaster mixture for freezing.
Mounting the
pad The plastic holder is used to fix the wall outlet and usually has a diameter of 68 mm. According to the method of installation there are two types: for gypsum board and for concrete.
Important! Before starting work, it is necessary to de-energize the room!
Drywall from
Drywall covers for gypsum board are fixed with screws and plastic clips. When installing such a juniper it is important to remember that the wires must be stretched to the right place before starting the installation of drywall. Using a level and a pencil, determine the center of the future outlet and drill a circle with a diameter of 68 mm( an electric drill with a crown or a conventional drill, but drilling a number of holes in a circle).
The dashboard is placed in the hole, pulling out the wires and tightening the screws, fixing the clamps.
Concrete wall( bricks)
The concrete pads are frozen into the prepared holes for them with alabaster or other plasters.
The most optimal procedure for installing the subgrid into concrete:
· Shtroblenie walls for wiring( at home use a perforator or bolgarku) - Stroby perform strictly vertically or horizontally. The width and depth of the strog is not more than 25 mm, the length is not more than 3 m.
· Shrinkage of the hole under the jar( it must freely enter the hole).
· Wiring and freezing of electrical wiring( leave free end at least 10 cm).
· Installation of the podrozetnik and setting of wires to it, freezing of the podzhezetnik.
Important! When building walls for wiring, SNiP 3.05.06-85 should be used.
Assembly of the
outlet The installation of the socket base starts after finishing works and operates in the following order:
- Strip the insulation from the insulation of the wire from the back wall( no more than 1 cm).
- Remove the cover from the base, unscrewing the central screw, and insert it into the jar and level the sockets horizontally. Mark holes for the side screws.
Remove the socket base and screw the wires to the base terminals. If there is only an incoming wire, then it consists of three wires( yellow-green color - ground, blue color - "zero", the third wire can be any color - this is the "phase").First, connect the ground, then "zero" and the remaining "phase".
Wire connection for grounding
If there is an input and output wire, the wires are connected in pairs.
Installation of the socket in the groove
· Lay the wires in the receptacle and, clamping the base of the socket, tighten the screws of the latches.
Installing the
outlet It only remains to put the cover back on the socket base. And the decorative frame is best to install after finishing the walls.
If several outlets are planned in a row, then they perform the same work.
Installation of sockets with earthing - open wiring
Open wiring is used in wooden houses or in rooms where stonework is considered impractical.
Stages of work:
· Identify the location of the future outlet.
· Route the wiring to the desired location.
· Screw the base of the socket, wire into it and fix it in the same way as in the case of an internal outlet.
· Install the socket cover, wiring harness in the protective box.
So it looks like an already installed socket with grounding
After completing all works check the correct connection of the outlet - supply electricity and measure the presence of current indicator( if available).
If the theoretical part of installing a grounded outlet is understandable, but there remains uncertainty and indecision, then it is best to entrust this work to a specialist.
