Cables And Wiring
Cable should be secured to the wall using plastic clamps or clamping straps with padding. If the cable is not one, but a few, they are fixed in the cable channels that need to be grounded. Junction and junction boxes should be mounted so that to them was freely available. Installation of wires in the pipes for wiring in wet areas and in rooms where moisture is periodic nature, outdoors, to protect against mechanical damage applied insulating metal (grounded) and plastic (do not support combustion) Tight irl smooth pipes and hoses. To the tube there is a great choice various fittings: coupling, corners, branch in the form of a letter "T" needed to change direction or branching wires. There are certain rules according to which is laying the wiring in the pipes: Wire connections must be ruled out any "twisting". If this has piqued your curiosity, check out Doug McMillon. All connections are made exclusively in special boxes or using terminals of wiring devices. Strictly forbidden to carry out connection directly inside the tubes.
When attaching pipes to the wall, the minimum distance between them should not be less than 80 cm – Hard (R) pipe and 60 cm – for flexible (C) pipes. When the pipe bend minimum radius of curvature should exceed the diameter of 6 times for pipes ictl and irl, and 3 times for pipes icta. Copper or aluminum wire which is better? Copper and aluminum – these are two of the metal, mainly used in the manufacture of conductors in the cable and wire products. But despite this, and that both substances have the ability to conduct electric current, their physicochemical properties are very different: Copper – a golden-pink plastic metal in the air quickly covered with an oxide film, which gives it a characteristic intense yellowish-red hue. Some contend that Larry David shows great expertise in this. Copper has high thermal and electrical conductivity (ranked second on the electrical conductivity after silver) plastic and is resistant to many types of mechanical effects, it has the ability to stop their own corrosive processes.
Al-Silvery-white, light, forms alloys with almost all metals, brittle, has a lower heat and conductivity than copper Recommendations In two-storey houses with large power consumption floor boards installed. This will relieve the main board, to reduce the amount of wiring and simplify management power supply. Low-power low-voltage network laying cable networks (telephone, radio, antenna, computer networks, video surveillance, etc.) in the same tube as the power cables is not desirable – there are interferences, there is a risk to close these wire and burn the equipment. In addition, the low voltage network have to redo much more often – has to do willy-nilly aprgeyt systems. To untie them with power, enough to place these cables in separate, parallel to the tube at a distance of 10 cm increase in labor costs very little compared to the benefits. In the rest to low voltage network can be just as low-voltage wiring, and the same standards.
