How installation of cartridges is carried out?

At first the cartridge case assort, having separated its parts, and extract the loose leaf. Then, having passed wires through an aperture in the top detail of a cartridge, do on them ringlets, isolate and attach screws to the loose leaf.

How switches are mounted?

Switches hapen two kinds: for the open and latent posting.

In the first case the assembly basis strengthen on a wall two screws, and on it two screws screw the switch.

In the second case the switch basis strengthen in a box for the drowned installation with the help raspornyih the pads strapped with an elastic band.

It is necessary to remember, that it is impossible to apply the big efforts at removal and installation of a key of the switch, and also to remove an elastic band strapping raspornyie pads. Wires should not touch keys.

How correctly to establish plug receptacles?

Let’s consider it on an example of a double plug receptacle for the latent posting. At first unscrew screws from apertures and remove a decorative cover. Then attach wires. The socket should not press a wire at all. Therefore in porcelain sockets for open installation under posting the aperture is made, and in covers of plastic sockets two thin membranes (them name podpressovkami) are possessed. Depending on from what party it is necessary to conduct wires, this or that podpressovka is broken out.

How to connect an electrodevice plug?

Plug assort, on wires do ringlets and attach them to plug pins. Collecting a plug, it is necessary to watch, that pins have strictly taken the places.

How installation of room electric calls is carried out?

The call and the button are attached directly to a network 127 or 220 V.Vse that is attached to the general electric network, should be mounted by the wires having isolation, calculated for pressure of a network. zvonkovyih, telephone wires to apply it is impossible: their isolation is insufficient. The button also should be calculated for pressure 220 Century

How installation of safety locks and knife switches is done?

Safety locks with back joining of wires are established on guards from an isolating material. Wires from a network attach to conclusions of the central contact, and load feed from conclusions which are connected to a safety lock sleeve. To knife switches pressure make so that on their mobile current carrying parts at the disconnected knife switch there was no pressure.

How the control metre is established?

In installation of the control metre very important that phase, instead of the zero wire passed through tokovuyu a winding of the metre.

The metre establish on a special guard together with safety devices in the places which are away from a zone of possible mechanical effects, from pipelines of heating, a gas pipeline and a waterpipe. The distance from them should be not less than 0,5 m.

Guard with the metre of 0,8-1,7 m in a dry premise with temperature during winter time not below 0 degrees possess at height. Posting from the introduction system to the metre execute a cable or the isolated wires without any mergings, a ration or other damages of integrity of isolation. Wires under a guard should not concern walls or it is necessary to put on isolating tubes them. Source: the Newspaper "Building" #42 (2004) heading «Stroyinform»
